I am using checkbox in a gridview:
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox ID="chkhdr" runat="server" AutoPostBack="true" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox CssClass="gridrownormal3" ID="chkChild" runat="server" />
</ItemTemplate>
</asp:TemplateField>
Button click for binding grid:
protected void Button1_Click(object sender, EventArgs e)
{
/*
* Clear All Data in Grid By Calling Empty_GridView
* */
if (this.IsValid)
{
Empty_GridView(grdDocList_Summary);
List<SearchEngineEO> doc = Docs;
var query18 = (from c in doc
select new { c.DocNO, c.DocType, c.Title, c.Padid,
c.PublisherName, c.PublishedDate,
c.Rade }).Distinct().ToList();
grdDocList_Summary.DataSource = query18;
grdDocList_Summary.DataBind();
}
}
I select the checkbox at run time, I want to show some details of these rows.
I use this code:
for (int i = 0; i < grdDocList_Summary.Rows.Count; i++)
{
GridViewRow row = grdDocList_Summary.Rows[i];
bool isChecked = ((CheckBox)row.FindControl("chkChild")).Checked;
if(isChecked)
{
String str = row.Cells[1].Text;
DocNos.Add(str);
}
}
Suppose I have 10 rows in grdDocList_Summary. When I select one checkbox, for all iteration of for above variable ischecked is true. Why does this happen?

Hi from this field in my gridview, I'd like to pass the id value when the select command field is clicked, but i don't want to have the id field visible so I have the visible property set to false; however, when I pass it on the SelectedIndexChanged event the value is "" yet when the visible property is set to "true" the text value passes fine. What is the correct way to do this?
<asp:BoundField DataField="Project_ID" Visible="false"/>
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
String ProjID = GridView1.SelectedRow.Cells[10].Text;
}
Try this:
.aspx
<asp:Gridview id="GridView1" runat="server" DataKeyNames="Project_ID" />
.cs
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
if(gridView.SelectedDataKey != null)
{
var selectedId = GridView1.SelectedDataKey.Value;
}
}
Here you'll find more info about DataKeys in Gridviews: http://msdn.microsoft.com/de-de/library/system.web.ui.webcontrols.gridview.selecteddatakey(v=vs.110).aspx
I have done something like this in winform maybe can help you. That is what i used
int rowindex = dataGridView1.CurrentRow.Index;
string ProjID= dataGridView1.Rows[rowindex].Cells[10].Value.ToString();
you could use HiddenField inside your gridView ItemTemplate to keep the ID and use it in onrowcommand event, like below:
.aspx
<asp:GridView ID="gridProject" runat="server"
onrowcommand="gridProject_RowCommand">
<Columns>
<ItemTemplate>
<asp:HiddenField ID="hidProjectID" runat="server"
Value='<%# ((DataRowView)Container.DataItem)["Project_ID"] %>' />
<asp:Button ID="btnProject" runat="server" Text="use pro id"
CommandArgument="<%# ((GridViewRow) Container).RowIndex %>"
CommandName="DoSomething"></asp:Button>
</ItemTemplate>
</Columns>
</asp:GridView>
aspx.cs
protected void gridProject_RowCommand(object sender, GridViewCommandEventArgs e)
{
int index = 0;
GridViewRow gridRow;
GridView grid = sender as GridView;
try
{
switch (e.CommandName)
{
case "DoSomething":
index = Convert.ToInt32(e.CommandArgument);
row= gridProject.Rows[index];
string Id = ((HiddenField)row.FindControl("hidProjectID")).Value;
//do whatever you want here
break;
// and you can have as many commands as you want here
}
}
catch { //display error }
}
if anyone can help me, I have problems with gridview, when I use OnRowEditing and OnRowDeleting and inside asp: TemplateField, ItemTemplate I am using a checkbox, when checked the checkbox in checkbox.checked value is never true,
below is my C # script
<asp: Button ID = "Button1" runat = "server" BackColor = "# EFF1F1" BorderStyle = "None"
onclick = "Button1_Click" Text = "Submit Work Program" />
<asp: GridView ID = "GV_program" runat = "server" AutoGenerateColumns = "False"
Its DataKeyNames = "KD_BIDANG" Width = "100%" AutoGenerateEditButton = "True"
AutoGenerateDeleteButton = "true" OnRowEditing = "GV_program_RowEditing"
OnRowDeleting = "GV_program_RowDeleting" OnRowDataBound = "GV_kegiatan_RowDataBound"
BackColor = "White" EmptyDataText = "No Data Activity" AllowPaging = "True">
<EmptyDataRowStyle BackColor="#FF9900" />
<Columns> <asp:TemplateField HeaderStyle-Width="20px"> <ItemTemplate>
<asp:CheckBox ID="cbSelect" runat="server" /> </ItemTemplate> </asp:TemplateField>
</ Columns> </ asp: GridView>
C #
protected void Button1_Click (object sender, EventArgs e)
{
foreach (GridViewRow row in GV_program.Rows)
{
if (((CheckBox) row.FindControl ("cbSelect")). Checked)
{
// Delete something (never get here)
}
}
}
take it one step at a time until you get it working......
Try this:
/* put this value at the "class level" */
public static readonly int GRID_VIEW_COLUMN_ORDINAL_chkBoxSELECT = 3; /* Your number may be different, its the ordinal column number. A static readonly or const value makes your code more readable IMHO */
/*Then in your method */
if (null != this.GV_program)
{
Control cntl = null;
foreach (GridViewRow gvr in this.GV_program.Rows)
{
cntl = gvr.Cells[GRID_VIEW_COLUMN_ORDINAL_chkBoxSELECT].FindControl("cbSelect");
CheckBox cbIsApproved = cntl as CheckBox;
if (null != cbIsApproved)
{
bool myValue = cbIsApproved.Checked;
}
}
}
I just ran this code, and it worked for me.
protected void imgbutSave_Click(object sender, ImageClickEventArgs e)
{
if (null != this.gvMain)
{
Control cntl = null;
string finalMsg = string.Empty;
int counter = 0;
StringBuilder sb = new StringBuilder();
foreach (GridViewRow gvr in this.gvMain.Rows)
{
counter++;
cntl = gvr.Cells[GRID_VIEW_COLUMN_ORDINAL_chkBoxIsApproved].FindControl("chkBoxIsApproved");
CheckBox cbIsApproved = cntl as CheckBox;
if (null != cbIsApproved)
{
sb.Append(string.Format("Row '{0}' (chkBoxIsApproved.Checked) = '{1}'", counter, cbIsApproved.Checked) + System.Environment.NewLine);
}
}
finalMsg = sb.ToString();
}
}
and my aspx code
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkBoxIsApproved" runat="server" Checked='<%#Eval("IsApproved")%>'>
</asp:CheckBox>
</ItemTemplate>
</asp:TemplateField>
My StringBuilder had all of the checkboxes on my page, with the correct .Checked value.
I have a gridView with 5 columns with Edit and Delete button on each row of GridView. Once an Edit button a particular row is clicked , I want to disable the edit and delete buttons on rest of the rows.
Below is my aspx
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" ShowFooter="True" EnableModelValidation="True" onrowdatabound="GridView1_RowDataBound" onrowcommand="GridView1_RowCommand" onrowdeleting="GridView1_RowDeleting" EditRowStyle-ForeColor="Aqua" onrowediting="GridView1_RowEditing" >

</ItemTemplate>
</asp:TemplateField>
</Columns>
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
int x = Convert.ToInt32(e.CommandArgument.ToString());
txtLineItemNumber.Text = (x + 1).ToString();
}
else
{
int x = Convert.ToInt32(e.CommandArgument.ToString());
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowIndex != x)
{
Button editButton = (Button)row.FindControl("btnEdit");
editButton.Enabled = false;
Button deleteButton = (Button)row.FindControl("btnDelete");
deleteButton.Enabled = false;
}
else
{
Button deleteButton = (Button)row.FindControl("btnDelete");
deleteButton.Text = "Cancel";
e.CommandName = "Cancel"; --- This is not possible...what should I do so that the Command Name is changed to Cancel and it does the cancel operation.
}
} }
}
Please help me to get it working.....
The approach you are taking will work fine. However the CommandArgument which is set in your markup CommandArgument='<%# DataBinder.Eval(Container, "RowIndex") %>' is not a reference to the Button itsself but the index of the GridView row the Button resides in.
You will need to retrieve the index from the CommandArgument in the RowCommand event and then enable/disable all buttons on other rows like so:
void gridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
switch (e.CommandName.ToLower())
{
case "edit":
{
int rowIndex = Convert.ToInt32(e.CommandArgument);
foreach (GridViewRow row in gridView1.Rows)
{
if (row.RowIndex != rowIndex)
{
Button editButton = (Button)row.FindControl("btnEdit");
editButton.Enabled = false;
Button deleteButton = (Button)row.FindControl("btnDelete");
deleteButton.Enabled = false;
}
}
}break;
}
}
Edit (based on comment)
Try moving the code that modifies the delete button to the RowEditing event handler like so:
void gridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
gridView1.EditIndex = e.NewEditIndex;
DataBind();
Button deleteButton = (Button)gridView1.Rows[e.NewEditIndex].FindControl("btnDelete");
deleteButton.Text = "Cancel";
deleteButton.CommandName = "Cancel";
}
void gridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
gridView1.EditIndex = -1;
DataBind();
}
Hope this helps.
You could use javascript, outlined here, http://www.krissteele.net/blogdetails.aspx?id=92 . Add logic to not disable for the current row.
Environment: ASP NET 2.0 - Production Server does not have Ajax Control Toolkit so no real Control toolkit to use here.
3 RadioButtons List:
List one loads, after postback, the item from list one is used to select a Lab value.
Once a lab value is selected a 3rd radiobuttonlist will populate. There are some textboxes but they are not shown in example. The textboxes postback themselves on changes. If both textboxes are
not empty, a record is created for the session.
Now if the 3rd radiobuttonlist is changed from the default a series of 3 hidden user controls appear which represent 3 levels of reasons for the change ( child/parent records in database ).
The problem I am having is when I select a different item on the radiobuttonlist the radiobutton 3 OnSelectedIndex is firing after my user controls fire. My user controls need the value of the 3rd list to go to the database and get the correct set of records associated with the lab.
The problem is because the last radiobuttonlist is not processed until after the web controls loads, the code to mount the user controls never happens.
Here is the basic HTML code:
<asp:RadioButtonList ID="rdoLab" runat="server" OnSelectedIndexChanged="rdoLab_OnSelectedIndexChange">
</asp:RadioButtonList>
<asp:TextBox ID="textbox1" runat="server" OnTextChanged="TextBoxProcess" />
<asp:TextBox ID="textbox2" runat="server" OnTextChanged="TextBoxProcess" />
<asp:RadioButtonList ID="rdoPrimary" RepeatColumns="3" OnSelectedIndexChanged="rdoPrimary_OnSelectedIndexChanged" runat="server" ToolTip="Select Normal, Hypo or Hyper - Normal is default value." AutoPostBack="True" >
<asp:ListItem Value="3" Text="Normal" Selected="true"/>
<asp:ListItem Value="1" Text="Hypo" />
<asp:ListItem Value="2" Text="Hyper" />
</asp:RadioButtonList>
<asp:Panel ID="UpdLab" runat="server" Visible="true" EnableViewState="true">
<asp:Table ID="tblAdmin" runat="server">
<asp:TableRow>
<asp:TableCell runat="server" id="tblCell1" Visible="false" CssClass="tdCell" VerticalAlign="top">
<uc1:Lab ID="Lab1" runat="server" EnableViewState="true" EnableTheming="true" />
</asp:TableCell>
<asp:TableCell runat="server" ID="tblCell2" Visible="false" CssClass="tdCell" VerticalAlign="top">
<uc1:Lab ID="Lab2" runat="server" EnableViewState="true" EnableTheming="true" />
</asp:TableCell>
<asp:TableCell runat="server" ID="tblCell3" Visible="false" CssClass="tdCell" VerticalAlign="top">
<uc1:Lab ID="Lab3" runat="server" EnableViewState="true" EnableTheming="true" />
</asp:TableCell>
</asp:TableRow>

{
// data in data base for this user, lab, doc identifier...
if (Convert.ToInt32(Session["rdoPrimary"]) > 0
{
// have user hdr data - see if item data is mapped...
// do some stuff here
}
}
}
}
I hope this is clear. I've att
---*--- Since original posting:
added simple javascript/OnDataBound
function Primary(object)
{
alert("Value Clicked :" + object);
}
protected void rdoPrimary_DataBound(object sender, EventArgs e)
{
RadioButtonList rdlPrimary = (RadioButtonList)sender;
foreach (ListItem li in rdlPrimary.Items)

li.Attributes.Add("onclick", "javascript:Primary('" + li.Value + "')");
}

Store and retrieve the values you want to retain in SaveViewState and LoadViewState methods and see if that works for you? Also look to the earlier and later lifecycle events for handling the logic - Init and OnPreRender. This has worked for me in the past.
I have a GridView that includes BoundField and TemplateField elements. Some of the TemplateField elements are dynamically generated. For the sake of reference, here is the GridView that I am using
<asp:GridView ID="myGridView" runat="server" AutoGenerateColumns="False"

</asp:GridView>
When the GridView initially loads, everything is loaded properly. However, anytime I perform a command (edit, insert, delete), all of the data goes away. Oddly, the BoundField values still appear correctly. However, any TemplateField does not seem to get rendered. The code that I am using to work with this GridView is here:

{

container.Controls.Add(textBox);
}
else if (listItemType == ListItemType.Header)
{
Literal literal = new Literal();
literal.Text = value1;
container.Controls.Add(literal);
}
else if (listItemType == ListItemType.Footer)
{

container.Controls.Add(textBox);
}
}

{
TextBox textBox = (TextBox)(sender);
GridViewRow row = (GridViewRow)(textBox.NamingContainer);

}
}
How do I use commands in a GridView with Dynamically added columns? What is wrong with my code?
Thank you!
Dynamically added controls must be added on each post, you can't just add these controls on the first page load. Try removing your BindGridData() from within the Page.IsPostBack == false.
