Data Controls :: Find And Access Control In GridView OnRowEditing Event
May 7, 2015
I have gridview in my page that users can edit their data in gridview below is code:
<asp:GridView ID="GridView1" runat="server" CssClass="DGridView1"
AutoGenerateColumns = "false" Font-Names = "Tahoma"
Font-Size = "9pt"
HeaderStyle-BackColor = "#e0e0e0"
OnPageIndexChanging = "OnPaging" onrowediting="EditCustomer"
onrowupdating="UpdateCustomer" onrowcancelingedit="CancelEdit"
GridLines = "Both" OnRowDataBound = "OnRowDataBound" >
I define Lable in gridview that I want when users click on edit it show s some text in this lable so I wrote editcustomer metod like below:
protected void EditCustomer(object sender, GridViewEditEventArgs e) {
Label3.Text = "neda";
GridView1.EditIndex = e.NewEditIndex;
BindData();
BindData1();
}
But this error happen:
the name "lable3" doesn't exist in current context
I know because I define it in gridview it can't recognize but how I can solve it?

I have a Gridview which contains templated column that has 5 checkboxes in it. When you click on one checkbox, I want to uncheck the other 4.
I am using the Item Template for this. I don't want the user to have to Select a row, before clicking on the checkboxes. Here is my non-working code to uncheck the other checkboxes. I realize it's not "SelectedRow" that I want since there's no selected row, so how do I find the row containing the checkbox that fired off CheckChanged?

I add one or more textbox controls to a repeater itemtemplate during OnItemDataBound.
The textbox controls are instantiated and then added to a placeholder.
My problem is getting the user entered values from those dynamically added textboxes. They do not seem to exist in the repeater items collection.

I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.
What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.

How do I access GridView Page Index in RowDataBound event? I am assigning PageIndex to hyperlink on the gridview, for this I was planning to use "GridView1.PageIndex" in rowdatabound event. Problem is when I got second page in gridview (10 rows per page), the first row in the page shows page index as "0" and from second row it becomes 1. And if I goto third page, the first row in the page shows page index as "1" and from second row it becomes 2.

I have a detailsview control, which I use to enter data and save to the database. I am using object datasource to connect to the db. The detailsview control has autogenerateinsert = "true". When the insert is successfull, I want to set some variables and and to redirect the page to a different one. I don't know how to access the insert button click event of the detailsview to do it. If there is different solution like using <insertItemTemplate> and using custom linkbuttons.
