asp:button column click event

[NishChaks]

Hi,
I am having a asp button column which onclick should open another page.
My code is in C# and goes like this.

private void dtICHQryDetails_ItemDataBound(object sender, DataGridItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.AlternatingItem) || (e.Item.ItemType == ListItemType.Item))
{
string strReqNo = e.Item.Cells[0].Text;
if (int.Parse(e.Item.Cells[0].Text) > 0)
{
e.Item.Cells[8].Attributes.Add("onclick", "javascript:OpenICHQryItem('" + strReqNo + "');");
e.Item.Attributes.Add("onclick", "javascript:OpenICHQryItem('" + strReqNo + "');");
}
}
}

javascript:
function OpenICHQryItem(txtReqNo)
{
location.href = "SRPICHOUTBIL.aspx?reqno=" + txtReqNo;
}

asp button column is the 8th cell in the grid.
Also e.Item.Attributes.Add(....) statement works,
but e.Item.Cells[8].Attributes.Add(..) doesn't work...

Can you please tell me how to solve this.

Thanks

Where are you adding the asp:button?
Just add the handler to it then?

what handler should I add to the button??

[Plater]

well you said that like e.Item.Cells[8] should be a button right? Where is it told that it's a button? Wherever that is, add the .Attributes.Add() statement?

Does e.Item.Cells[8] have a .Controls ? because if it does, check it. It might be that the actual BUTTON control is a sub control of e.Item.Cells[8]
So you might have do something like e.Item.Cells[8].Controls[0].Attributes.Add()
