Need value of gridview row onrowdeleting - asp.net

I can't get the value. What I do get is a blank value or videoName = " ". How can I get the value of videoName? In the rowdeleting event, I am using Rows(e.Index).Cells(2).Text to get the value but it is blank. Is there another way to get the field, "videoname"?
Protected Sub GridView1_RowDeleting(sender As Object, e As GridViewDeleteEventArgs)
Dim videoName As String = gridview1.Rows(e.RowIndex).Cells(2).Text
Dim val As String = videoName
If File.Exists(HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ApplicationPath) + "\contents\published" + videoName) Then
File.Delete(HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ApplicationPath) + "\contents\published" + videoName)
End If
End Sub

This is prone to erros when you add or delete a column from gridview in future your code would fail again. I suggest you use a label inside template field for your MovieName field & use FindControl to find your label.
Aspx
<asp:TemplateField HeaderText="Movie Name" >
<ItemTemplate>
<asp:Label ID="lblMovieName" Text='<%#Bind("MovieName") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
Code behind
protected void gvCustomer_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
Label lblMovieName = gvCustomer.Rows[e.RowIndex].FindControl("yourLableControlName") as Label;
// Perform your delete
}
Updated
I found that in your code you have the movieName Visibleproperty set to false. This will prevent it from rendering on page. You can either store values in DataKeys or remove visible=false to fetch desired value.

Error when passing values from dataview to datatable rowcell

I have a page with two gridview; one is inside the modal pop up (grdEmpName) and the other is in the page (gvUser). Now, when the user select search button the modal pop up extender will pop up and then search employees. When the user select someone, the selected data should display to the textbox in the another gridview (gvUser).
Everything is working up to selection in modal pop up extender gridview (grdEmpName)but when I select no data pass to the other gridview. (gvUser). I need to display the selected data in the textbox.

Now, here's may code for selectedEmployee (Radio Button)
Protected Sub selectedEmployee(ByVal sender As Object, ByVal e As System.EventArgs)
Dim lnBTNDone As RadioButton = DirectCast(sender, RadioButton)
Dim row As GridViewRow = DirectCast(lnBTNDone.NamingContainer, GridViewRow)
Dim RowIndex As Integer = gvUser.EditIndex
Dim dt As New DataTable
dt = TryCast(Session("dbCache_User"), DataView).Table.Copy
Dim dv As New DataView(dt, "", "USR_IDNTY", DataViewRowState.OriginalRows)
Dim s As String = TryCast(gvUser.Rows(RowIndex).FindControl("lblUSR_IDNTY"), Label).Text
Dim idx As Integer = dv.Find(s)
dv(idx)("USR_ID") = row.Cells(1).Text
dv(idx)("NAME") = row.Cells(2).Text
dv(idx)("EMAIL") = row.Cells(3).Text
gvUser.DataSource = dv
gvUser.DataBind()
Me.mdlEmpListProcess.Hide()
End Sub
But I've encounter this error when debugging system.data.dataexception was unhandled by user code. Cannot set Name when passing the value.
dv(idx)("NAME") = row.Cells(2).Text
as per you comment NAME is readonly field error given at runtime than you make is readonly false as below , add same line in your code after reading value
dt.Columns["NAME"].ReadOnly = false
Working example
DataTable dataTable = new DataTable("dataTable");
DataColumn dataColumn = new DataColumn("dataColumn");
dataTable.Columns.Add(dataColumn);
// Add ten rows.
DataRow dataRow;
for (int i = 0; i < 10; i++)
{
dataRow = dataTable.NewRow();
dataRow["dataColumn"] = "item " + i;
dataTable.Rows.Add(dataRow);
}
dataTable.AcceptChanges();///add this line in your code
var dv = new DataView(dataTable, "", "dataColumn", DataViewRowState.OriginalRows);
int index = dv.Find("item 1");
if (index == -1)
Console.WriteLine("Product not found");
else
dv[index]["dataColumn"] = "item 1000";
I suggest first check you are able to find row or not
int idx = dv.Find(s);
if (index == -1)
{
Console.WriteLine ("Product not found");
}
else
{
dv[index]["columnname"] = "value";
}

How to Enable a DropDownList in Gridview When Selected the First DropDownList

I'm working with my GridView table in ASP.Net.
First when I click the Edit link button in my GridView I will be able to edit it with Textbox and dropdownlist.
Here's the image of my GridView.
So the Business Unit was enabled but the Division, Sub-Division, Classification and Sub-Classification are not.
My problem is that when I select the Business Unit, the dropdownlist Division should be enabled and be able to select the value according to the Business Unit that I selected and so on. So the next dropdownlist will be dependent on the first dropdownlist that you selected. I searched about this on the internet already and tried different solutions but I'm still confused and don't know how it will work.
Here's my code in ASP.Net

Protected Sub gvGroup_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvGroup.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
If (e.Row.RowState And DataControlRowState.Edit) > 0 Then
Dim ddlBusinessUnit As DropDownList = DirectCast(e.Row.FindControl("ddl_gvBusinessUnit"), DropDownList)
'bind dropdown-list
Dim sqlstr As String
Dim dt As DataTable = New DataTable()
sqlstr = "Select BUSINESS_UNIT from BUSINESS_UNIT_TBL"
dt = ehr_utils.DataTable(sqlstr)
ddlBusinessUnit.DataSource = dt
ddlBusinessUnit.DataTextField = "BUSINESS_UNIT"
ddlBusinessUnit.DataValueField = "BUSINESS_UNIT"
ddlBusinessUnit.DataBind()
Dim dr As DataRowView = TryCast(e.Row.DataItem, DataRowView)
ddlBusinessUnit.SelectedValue = dr("BUSINESS_UNIT").ToString()
End If
End If
End Sub
Any idea of how can I possibly do that? And I tried also the OnSelectedIndexChanged
First you need to add an OnSelectedIndexChanged to ddl_gvBusinessUnit and set AutoPostBack to true
<asp:DropDownList ID="ddl_gvBusinessUnit" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddl_gvBusinessUnit_SelectedIndexChanged">
And then in code behind
protected void ddl_gvBusinessUnit_SelectedIndexChanged(object sender, EventArgs e)
{
//cast the sender back to a dropdownlist
DropDownList dropDownList1 = sender as DropDownList;
//get the selectedvalue
string value = dropDownList1.SelectedValue;
//find the other dropdownlist in the correct row by using the editindex
DropDownList dropDownList2 = gvBusinessUnit.Rows[gvBusinessUnit.EditIndex].FindControl("DropDownList2") as DropDownList;
//do stuff with the other dropdownlist, like give it a color or add database values based on the first dropdownlist
dropDownList2.BackColor = Color.Red;
}
VB
Protected Sub ddl_gvBusinessUnit_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
'cast the sender back to a dropdownlist
Dim dropDownList1 As DropDownList = CType(sender,DropDownList)
'get the selectedvalue
Dim value As String = dropDownList1.SelectedValue
'find the other dropdownlist in the correct row by using the editindex
Dim dropDownList2 As DropDownList = CType(gvBusinessUnit.Rows(gvBusinessUnit.EditIndex).FindControl("DropDownList2"),DropDownList)
'do stuff with the other dropdownlist, like give it a color or add database values based on the first dropdownlist
dropDownList2.BackColor = Color.Red

CheckedChanged Event in a Gridview checkbox to update hidden labels

I have a gridview where the first column are check boxes, the next column is ID's. I have hidden labels on the page that need to get the current ID for any check boxes checked. The labels are specific, hlbl_pain1, hlbl_pain2, hlbl_pain3. It doenst matter which label gets which ID I just need each of the 3 hidden labels to be populated with ID's. Right now on CheckedChanged the 3 labels all update with the same value. I'm having issues looping. This is in VB.
Here's my grid:
<asp:GridView ID="gv_pain" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" DataSourceID="ds_grid_pain" ForeColor="Black" GridLines="Vertical" style="text-align: left; font-size: x-small; ">

Here's what I'm trying to do in my CheckedChanged in the codebehind:
Protected Sub CheckBoxPain_CheckedChanged(sender As Object, e As System.EventArgs)
Dim row As GridViewRow
For Each row In gv_pain.Rows
Dim cbPain As CheckBox = row.FindControl("CheckBoxPain")
If cbPain.Checked = True Then
Dim lblDrugID As Label = row.FindControl("lbl_DrugID")
hlbl_pain1.Text = lblDrugID.text
End If
Dim cbPain1 As CheckBox = row.FindControl("CheckBoxPain")
If cbPain1.Checked = True Then
Dim lblDrugID As Label = row.FindControl("lbl_DrugID")
hlbl_pain2.Text = lblDrugID.text
End If
Dim cbPain2 As CheckBox = row.FindControl("CheckBoxPain")
If cbPain2.Checked = True Then
Dim lblDrugID As Label = row.FindControl("lbl_DrugID")
hlbl_pain3.Text = lblDrugID.text
End If
Next

SortParameterName="sortBy" MaximumRowsParameterName="pageSize" SelectCountMethod="GetMenuCount">
</asp:ObjectDataSource>
I want to do the <asp:CheckBox ID="chkHeaderApprove" > checked when all my <asp:CheckBox ID="chkApprove"> is checked??
I am not able to do this please help me some more....
Add this:
<asp:CheckBox ID="chkApprove" runat="server" Checked='<%# Eval("ViewStatus").ToString().Trim() == "1" ? true : false %>' OnCheckedChanged="chkApprove_CheckChanged"/>
And in code behind:
protected void chkApprove_CheckChanged(object sender, EventArgs e)
{
CheckBox cb = (CheckBox)sender;
GridView g1 = (GridView)cb.Parent.Parent;
foreach (GridViewRow item in g1.Rows)
{
CheckBox currentCheckBox = (CheckBox)item.FindControl("chkApprove");
if (currentCheckBox.Checked != true)
return;
}
CheckBox chkHeaderApprove = (CheckBox)g1.FindControl("chkHeaderApprove");
chkHeaderApprove.Checked = true;
}
This should work.. didn't check. Anyways client side should be better, go for that.. This is just a easy server side solution.

want to fill the grid from database and check/uncheck the checkboxes from database condition. How to fill the gridview ...................................................................................
On which condition you want to check /Un-check the chechbox?
you can write code on RowDataBound event of grid.
void CustomersGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
// here check the condition and find the check box of current row and set it checked/uncheked
}
}
