Hi,
   i am facing a problem with the checkboxes displayed in the datagrid.when the data are displayed, one of the columns has the checkboxes.Now i want that when i select some checkboxes, the rows corresponding to those selected, should be updated or deleted. I tried this using datagriditem and using a loop to search the entire data. But how can i get the value of the checkboxes to see whether it is checked or not ? Please give some idea.

You can use FindControl Method like this
(chkSelect is name of CheckBox Control in Datagrid)

Dim dtgItem As DataGridItem
Dim chkControl As CheckBox

For Each dtgItem In Datagrid1.Items
    chkControl = dtgItem.FindControl("chkSelect")
    If chkControl.Checked = True Then
        ' do something ...
    Else
        ' do something ...
    End If
Next

Hi, I did as you said.I took one integer variable " i " and set its initial value to 1. Then in the If part I increment it by 1 and doing nothing in the else part.At last after it comes out from the loop i printed it in a label.But the problem is everytime the value of the integer is coming out as 1, the initial value.Again when I tried to increment " i " in the else part, it is incrementing but taking all the values of the checkboxes, if there are 4 checkboxes, value becomes 5, if there are 7, value becomes 8 , like this. What should i do now ? Please givew some idea.
