My code is as below and my problem is that when I used this code in Visual Studio
2008 it will not work properly. (I used this in my office, but not working)
Actually problem is that when I try to select the check box it cannot be selected.
Auto post back is true.

        GridViewRow gvr=(GridViewRow) cb.NamingContainer;
        int rrowindex = gvr.RowIndex;
        CheckBox cbb = (CheckBox)GridView1.Rows[rrowindex].Cells[6].Controls[1];
        TextBox txt=(TextBox)GridView1.Rows[rrowindex].Cells[6].Controls[2];
            if (cbb.Checked)
                txt.Visible = true;
            if (cbb.Checked == false)
                txt.Visible = false;

hey bros ..give response...

It looks like you have the checked state = false. If I am not mistaken, a checkbox is always unchecked by default. Try removing the "checked="false" and see if that will allow you to check it then... Though I almost never use checkboxes, so don't hold me to it.

bro, u r right, but i tried also by removing this "checked=false" but it not working...
actually my this code work well in vs2010 but when i use this code in my vs2008 , than there is problem accour, i select the checkbox but it cann't be selected..
Member 8197993 at 25-Dec-12 10:39am
Is there a particular reason you are going back and forth between 2010 and 2008? Which platform are you developing under? I use 2010 myself, and am not familiar with 2008 and what changes there are between the 2.

Solution 1

so if you have a checkbox for each row of the grid using template field, and upon checking the checkbox you want to show a textbox as visible? try this solution below, you can convert it to c#.
For Each row As GridViewRow In GridView.Rows
    Dim cbb As CheckBox = DirectCast(row.FindControl("CheckBox1"), CheckBox)
    Dim txt As Textbox = DirectCast(row.FindControl("textbox1"), textbox)
    If checkbox.Checked Then
        Dim rowid As Integer = Convert.ToInt32(GridView.DataKeys(row.RowIndex).Value)
        If cbb.Checked = False Then
    txt.Visible = False
    End If
