i am working without using data base only delete from gridview.
I am trying to delete multiple rows using a checkbox in a Gridview. When someone checks the checkbox and then click on button Delete that the rows is chosen will be deleting.
GUI:
[Code]....
when i click on button Delete : Error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I have a grid in which multiple delete is to be implemented but before deletion it should show confrmation box which will ask to delete or not.
But this confirmation bo must be an ajax modal popup extender confirmation box not javascript.
My code for multiple delete:
protected void annDelete_Click(object sender, EventArgs e) {
foreach (GridViewRow row in GridView1.Rows) {
CheckBox cb = (CheckBox)row.FindControl("chk_delete");
if (cb.Checked && cb != null) {
{
modalconfirmbox.show();
int ID_No = Convert.ToInt32(GridView1.DataKeys[row.RowIndex].Value);
//code to delete where id =ID_No and bindgrid
} }
} }
This delete code is working and confirmation is appering. but you click yes or no or click none in modalconfirm rows will be deleted.

I'm a novice programmer and I have this situation: I have a nested Gridview, and I want to be able to DELETE the records in the nested Gridview. I have no problem inserting new records with the nested gridview, but it does not execute the DELETE Command on the SQL Datasource. I checked that the DATAKEYNAME on the nested gridview includes the the parameter that is used in the DELETE SQL Command on the SQL Datasource for that Gridview. But it seems to me that the parameter value is not being passed to the SQL Datasource by the nested gridview. Maybe I need to use a difference approach to execute this on a nested gridview compared to a regular gridview.

I'm fairly new working with Javascript. I'm working on an issue where I have a GridView with multiple Checkboxes and Radiobuttons. A user can check multiple checkboxes and if a radiobutton is selected, a checkbox has to be selected. This scenario is working fine, presently with existing asp.net code. But, I want to automate it using Javascript, so that I could avoid a postback.

Is it possible to have an edit function, so you can edit the expanded records - fx if you want to add/correct information.
Adding a normal edit/delete button like on a normal gridview doesn't seem to work when it is nested.
I've got this page where I display a 3 level nested gridview. First gridview displays data, 2nd one displays data based on the 1st one's row and 3rd one displays data based on the 2nd gridview. All of this works perfectly, including the edit mode for the 3rd gridview.
The issue comes when I make each gridview collapsible, again, it works fine but when I click on "Edit" on the 3rd gridview all the grids collapse, I can then re-open them and the "edit mode" is still present and I can still save my updated data. But that collapsing thing is quite annoying. I based a lot of my code from this page: [URL] And I understand how I can fix my issue on a 2 level nested gridview, by simply adding the C# code:
[Code]....
This makes allows me to save the index and prevent it from collapsing when I'm editing. Unfortunately, because I'm actually editing the 3rd gridview, if I code:

That simply doesn't work because I get the error "GridView2 does not exist in the current context". I also tried adding it to the .designer.cs page, but that doesn't change anything and still doesn't work. I'm not at work atm, and hence cannot paste the entire code, however, would anyone still have any idea as to how I can fix that issue?
