i want to know status is active or not in check box. how to bind check box with database data. while editing im lossing previous data. data is not showing in check box
code behind updating event
cmd.Parameters.AddWithValue("#LeadsAccess", ChkLeads.Checked);
<asp:TemplateField HeaderText="Leads">
<ItemTemplate>
<asp:CheckBox ID="ChkLeads" runat="server" />
</ItemTemplate>
</asp:TemplateField>
db column- [Leads]
You can try like this
<asp:CheckBox ID="ChkLeads" runat="server"
Checked='<%#bool.Parse(Eval("columnName").ToString())%>' />
try this..
you can bind the db value like this..
<asp:CheckBox ID="ChkLeads" runat="server" AutoPostBack="true" Checked='<%#Convert.ToBoolean(Eval("LeadsAccess"))%>'/>

I use PNM Sequence. And I need to make one grid column as the mandatory field.
I know how to make it with any separate control. E.g. I can type:
<sq8:GridBoundColumn DataField="txtField" HeaderText="txtField"
SortExpression="txtField" UniqueName="txtField" FilterControlAltText="">
<ColumnValidationSettings>
<RequiredFieldValidator ForeColor=""></RequiredFieldValidator>
</ColumnValidationSettings>
</sq8:GridBoundColumn>
And I can use this Validator for the TextBox:
<sq8:Label runat="server" Text="Field:" ID="Label1" Width="100%"></sq8:Label>
<nobr>
<sq8:TextBox runat="server" ID="txtField" Width="100%"></sq8:TextBox>
<sq8:RequiredFieldValidator runat="server"
ErrorMessage="RequiredFieldValidator"
ID="RequiredFieldValidator4"
ControlToValidate="txtField"
SetFocusOnError="True">*</sq8:RequiredFieldValidator>
</nobr>
<sq:BindableControl runat="server" TargetControlID="txtField"
DataField="txtField"></sq:BindableControl>
And it works. User can't send the form because he gets an error - the field is empty.
But I need to do the same with grid.
When I open "Edit columns" in Grid Wizard I can't see any property as "mandatory" or something like this.
And the code with RequiredFieldValidator doesn't work with a grid column. If I try to use it:
<Columns>
<sq8:GridBoundColumn DataField="txtFieldGrid" HeaderText="txtFieldGrid"
SortExpression="txtFieldGrid" UniqueName="txtFieldGrid"
FilterControlAltText="">
<sq8:RequiredFieldValidator runat="server"
ErrorMessage="RequiredFieldValidator"
ID="RequiredFieldValidator4"
ControlToValidate="txtFieldGrid"
SetFocusOnError="True">*</sq8:RequiredFieldValidator>
<sq:BindableControl runat="server" TargetControlID="txtFieldGrid"
DataField="txtFieldGrid"></sq:BindableControl>
</sq8:GridBoundColumn>
</Columns>
In this case, I have an error:
Is there some method for grid column validation? Or it's impossible with a grid?
Maybe I can use some javascript?
In my code I have this bind set up to a textbox
<asp:TextBox ID="CompanyTextBox" runat="server" Text='<%# Bind("Company") %>' CssClass="txtbox" />
Is there a way a way to access the "Company" value and change it programmatically, or do I simply change the value of the textbox and It will update accordingly?

I have an asp.net web page where i have a checkbox control inside gridview control as under
<asp:GridView ID="grdMergeCoverage" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<input type="checkbox" id="chkSelectStream" onclick="OnSelectionChanged(this);"
testrunid='<%#DataBinder.Eval(Container.DataItem,"TestRunId") %>'
checked='<%#DataBinder.Eval(Container.DataItem,"CodeCoverageRequired") %>'
servername='<%#DataBinder.Eval(Container.DataItem,"ServerName") %>'
runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
And the OnSelectionChanged function is as under
function OnSelectionChanged(id)
{
alert(id.testrunid);
alert(id.servername);
alert(id.checked);
}
In IE8 , I am able to get the value for testrunid,servername while in IE 9, it is coming as NULL.
What is the problem and how can i get the value in all the cases?
To get custom attributes you should use the getAttribute method.
Like so: id.getAttribute("servername").
The way you used to get the value before is non-standard and not always supported.
you can add the asp checkbox and add the attribute to it on the gridview rowitembound event. it will fire....
i'm loosing my mind. Using ASP.NET in a GridView, amongst other controls, I have the following:
<asp:TemplateField HeaderText="Intention">
<EditItemTemplate>
<asp:TextBox ID="IntentionInfo" Enabled="true" TextMode="MultiLine" Wrap="true" runat="server" />
</EditItemTemplate>
<ItemTemplate>
<asp:TextBox ID="IntentionInfo" Enabled="false" TextMode="MultiLine" runat="server" />
</ItemTemplate>
</asp:TemplateField>
I would like to take the value out of this textarea and save in a database. However, server side, I try to pull the value out, like such:
string txt = (TextBox)DonationResultsTable.Rows[e.RowIndex].Cells[6].Controls[1].Text;
... but I keep getting the value that was SENT to the Client.
I wrote this javascript and I can see the values change in the DOM, but still the server keeps taking the old value.
$("textarea").change(function()
{
var txt = $(this).val();
$(this).html(txt).text(txt);
});
So my guess was ViewState, but I disabled it for those controls, like this:
<asp:TextBox ID="IntentionInfo" ViewStateMode="Disabled" Enabled="false" TextMode="MultiLine" runat="server" />
Still nothing! Any ideas?
One option could be to use a hidden field and update it on text changed for the text area. You could do this with jQuery like this:
$("textarea[id$=tbTest]").change(function () {
$("input[id$=hdnVal]").val($("textarea[id$=tbTest]").val());
});
Then on the server side, you can retrieve the hidden field's value and save it to your database.
So in this gridview, there is a column for status and I want to have a drop down list with Pass, Pending, Fail appear when the edit button is clicked. These values are already in a table, so I need to somehow bind from this table to each ddl for every row.
Here is the column from the gridview. As you can see, I would like to just have a label showing when not in edit mode, and a ddl when the edit button is pressed
<asp:TemplateField HeaderText="During Production Status" SortExpression="DuringProductionStatus">
<EditItemTemplate>
<asp:DropDownList ID="ddlStatus" runat="server" datavaluefield="Name"
datatextfield="Name" DataSource="*What goes here?*"> />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblStatus" runat="server"
Text='I don't understand how to get this from the ddl' />
</ItemTemplate>
</asp:TemplateField>
For clarity's sake, my table is named Status, and the database is named DirectImport
There's a few steps to go through here - none of them are particularly difficult, but they can be a bit fiddly (IMHO). The good news is once you've got this working once, it gets easier to do it again!
I'm assuming you've got a <asp:*DataSource> control on your page - my preference is for an ObjectDataSource but I don't think it matters, I think a SqlDataSource works equally well. I've never tried doing this with GridView.DataSource = MyDataSet in code-behind, so I don't know whether that would work or not, but my assumption is that it wouldn't as you wouldn't get the proper two-way binding that you want. This data source feeds your grid with your main data. The key point here is that your database query must return both the Status text field and the Status id.
So your gridview will now look something like:
<asp:objectdatasource runat="server" id="MainDataSource" ... />
<asp:gridview runat="server" id="MyGridView" DataSourceID="MainDataSource">
<Columns>
<asp:TemplateField HeaderText="During Production Status" SortExpression="DuringProductionStatus">
<ItemTemplate>
<asp:Label ID="lblStatus" runat="server"
Text="<%# Bind('Status') %>" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:gridview>
The Text="<%# Bind('Status') %>" is the bit you're missing to get the status text into the grid.
Now add a second data source into your markup that reads in the set of values from the Status table.
<asp:objectdatasource runat="server" id="StatusObjectDataSource" ... />
And add the EditItemTemplate into the GridView, which is bound to the Status DataSource.
<EditItemTemplate>
<asp:DropDownList ID="ddlStatus" runat="server" datavaluefield="StatusID"
datatextfield="Status" DataSourceID="StatusObjectDataSource"
SelectedValue="<%# Bind('StatusId') %>" />
</EditItemTemplate>
The SelectedValue="<%# Bind('StatusId') %>" is what connects up the two datasets so that when you flip a row into Edit mode, the dropdownlist has the correct item already selected, and when you then save it you've got the Status ID to put into your database.
And you're done.
I have used the RowDataBound event. Here is a small code snippet. HTH
you would have an ItemTemplate in your aspx/ascx
<asp:TemplateField HeaderText="Column Headings">
<ItemTemplate>
<asp:DropDownList ID="ddlName" runat="server" Width="150"></asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
and in your code behind, you will have
protected void grdDataMap_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddl = (DropDownList)e.Row.FindControl("ddlName");
ddl.DataSource = someList;//the source of your dropdown
ddl.DataBind();
}
}
so when you bind your grid with grdDataMap.Databind (assuming your grid id is grdDataMap), row databound event will be called for each row (including header/footer, and thats the reason you check RowType)
so you can probably decide what controls/columns to hide/show/bind inside this row databound event
In the winforms world I pull my objects from the DB into a List(Of Whatever) and use the list as the datasource.
This also lets me add extra "convenience" fields in the object so that I can populate it with stuff from other tables.
I don't know asp.net at all so if you can do something similar, it might help.
A really quick solution is to create a custom web control for the status dropdown. The control will always contain the same data. When it renders you populate the datasource. When it gets added to the gridview, the data will be in the drop down. Hope that helps!
