I have a GridView with checkbox, dropdown and button as templatefields.
On button click I have to update the entire row in the data base.

This is the updatebutton event
protected void BtnUpdateRow_Click(object sender, EventArgs e)
{
Button btn = (Button)sender;
GridViewRow grow = (GridViewRow)btn.NamingContainer;
//btn.
CheckBox chkbx = (CheckBox)grow.FindControl("chkRow");
if (chkbx.Checked != true)
{
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Red;
labelErrormessage.Text = "Please Check/Uncheck the CheckBox and Click Update";
return;
}
else
{
/*--Code to update the row's record in the edatabase.--*/
??
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Green;
labelErrormessage.Text = "Updated Succesfully";
return;
}
}
How do I read the row in which the button has been clicked and update its dropdownlist selected values in the database?
If you have some sort of identification data displayed in the gridview you could get the value from the row's cell like this grow.Cells[0].Text then find the record in the database and update its values.
You could also hide the id for example if this is information you dont want to show to the user. The row will still be located at index 0 but hidden.
Sample:
else
{
var record = queryDatabase(grow.Cells[0].Text);
//update record values
updateRecord(record);
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Green;
labelErrormessage.Text = "Updated Succesfully";
return;
}
I have a custom gridview and I use that grid in too many pages and I want to set the SortExpression text for all columns inside that grid in code behained ; as you see in the following code I have do that by overriding the OnRowDataBound eventhandler .
The problem is I can't access the evaluated datafield expression text ("START_WORK_DATE" in my case) for template Fields like what I did in BoundField

Code behind:
protected override void OnRowDataBound(GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
for (int i = 0; i < this.Columns.Count; i++)
{
if (this.Columns[i] is BoundField)
{
if (((BoundField)(this.Columns[i])).DataField != string.Empty)
{
this.Columns[i].SortExpression = ((BoundField)(this.Columns[i])).DataField;
}
}
else if (this.Columns[i] is TemplateField)
{
// ???
}
}
}
}
You can do some thing like this. Set a header template with link button.
<asp:TemplateField>
<HeaderTemplate>
<asp:LinkButton ID="LinkButtonEmpName" runat="server" Text="Employee Name" CommandName="Sort" CommandArgument="Employees">
</asp:LinkButton>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="LabelEmployee" runat="server" Text='<%# Bind("Employees") %>'/>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="TextBoxEmployee" runat="server"/>
</FooterTemplate>
And in row command event find command like this.
protected void grd_RowCommand(object sender, GridViewCommandEventArgs e){
if (e.CommandName.Equals("Sort"))
{
FilterExpression = e.CommandArgument.ToString() + " LIKE '%" + txtCaseNumber.Text + "%'";
BindGridView();
}}
See the complete example here.

I have a gridView which works nicely until I open a new window by clicking a button. When the new window is opened the values in one of the columns 'lblTotalPrice' gets erased. 'lblTotalPrice' is a template field, which is calculated in MealList_RowDataBound (quantity * price). The footer for the column, however is not affected when the new window is opened (also gets its value in MealList_RowDataBound).
Also the font-size of the data-bound columns are changed when the new window is opened.
Any ideas of what might cause this? When stepping through the code there are no other lines executed after btnEnvComment_Click
When gridView is databound again, everything is back to normal.
The gridView:

}
}
}
the drop down selectedindexchanged event does not fire. I am trying to do as my drop down value changes at run time , in my database value get updates.
remove the event handler adding code from PaperReviewing_RowDataBound since you are already attached it from the markup
in your page load
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
DataBindGrid();
}
}
I have one sharepoint custom page application which is rendering from a user control. In the user control page, i had used SPGridview for displaying data. My first column is Title Column (link button column), when the user click on the link, then one popup window will open with corresponding data. But the problem is the link button is not working properly. But this application is working as fine in asp.net application.

//pnlSubmitModal_ModalPopupExtender.Show();
ScriptManager.RegisterStartupScript(this, this.GetType(), "starScript", "popUpWindow('" + strFilname + "?tittle=" + subject + "', 800, 690,'" + WindowName + "');", true);
this.Controls.Add(new LiteralControl("<script>alert('hi');</script>"));

If i click on the link button, there will be only post back occuring. but not the popup window open.. Please help me for resolving this problem. thanks in advance..
Have you checked to see if you're receiving a javascript error on the click?
Have you tried setting UpdatePanel2's UpdateMode="Conditional" and then adding Triggers? (button click)
Like this sample:
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="lbtnSubject" EventName="Click" />
</Triggers>
