{
foreach (GridViewRow row in gvActList.Rows)
{
RadioButton rdYes= (RadioButton)row.FindControl("rdYes");
RadioButton rdNo = (RadioButton)row.FindControl("rdNo");
RadioButton rdNone = (RadioButton)row.FindControl("rdNone");
if (rdYes != null && rdNo != null && rdNone != null)
{
if (rdYes.Checked == true)
{
//some code
}
else if (rdNo.Checked == true)
{
//some code
}
}
}
}
}
You can use above code on the button click. One suggestion is to use RadiobuttonList instead of RadioButton so that it will reduce the code.

on button click declare a gridview row. make a for loop and find the radio button in each row and other controls whose value you want to update. check the conditions as per your requirement and update accordingly

To grab Html of server control , I use below code
protected void btnOK_Click(object sender, EventArgs e)
{
var sb = new StringBuilder();
DivEmail.RenderControl(new HtmlTextWriter(new StringWriter(sb)));
EmailContent += sb.ToString();
}
public override void VerifyRenderingInServerForm(Control control)
{
/* Confirms that an HtmlForm control is rendered for the specified ASP.NET
server control at run time. */
}
By doing such , I m getting Exception
RegisterForEventValidation can only be called during Render()
I googled a bit on the issue, results says to set EnableEventValidation="false" in #page directive. but I can not use this solution.
Can anybody help me on this to solve??

Response.Write(I want to get the deleted seatOrderID here!!!!!);
}

Using this code, you can fetch the ID in the RowDeleting event:
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
GridViewRow gvr = (GridViewRow)GridView1.Rows[e.RowIndex];
string id = String.Empty;
Label lbl = (gvr.FindControl("Label1") as Label)
if (lbl != null)
{
id = lbl.Text;
}
}
You can fetch any control in the row, using the FindControl() method.

How to bind hovermenuextender control to a row with multiple columns in a dynamic gridview?

I wish to attach a hovermenu pop up to rows of a gridview which is dynamically populated from a datasource. I tried to set TargetcontrolId property of hovermenuextender control to row unique Id on occurence of rowdatabound event. But rather than appearing on the right side of each row, pop up is appearing on the right side of header row. Can somebody help me resolve this problem? I used below code for the same
CodeBehind:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HoverMenuExtender hoverMenu =(HoverMenuExtender)e.Row.FindControl("hme2");
if (hoverMenu != null)
{
hoverMenu.TargetControlID = hoverMenu.Parent.Parent.UniqueID;
}
}
}
}

Nested grid edit doesn't work

I'm stuck on this problem where I have grid within grid where the nested grid is editable. I can't get the edit working. What's complicates things is that the nested grid is inside a modal popup extender.
It works to the point where I click on the edit button. Then the EmptyDataText property kicks in with the message. If I click on it second time the grid opens in edit mode but the update/cancel buttons don't work. The cancel button when click displays the EmptyDataText property.
Another issue is that this nested grid doesn't use a object data source so I'm going to have to all the updating and deleting in the code file. Not sure now to do that either.
I would like some advice as to how to make this corrected. Here is the code:

I will try to answer part of your question, updating and deleting the code. you need to take advantage of the "onrowcommand" for the inner gridview (OnRowCommand).
