Hi

i have one datagrid and 4 checkboxes(asume chk1,chk2,chk3,chk4) in my web form.
when ever user checked the
chk3 then only i want to show edit option in datagrid.

i tried following 2 ways but both failed

 1. degign time i declared my datagrid as
    <asp:datagrid id="grd" AutoGenerateColumns="true" OnCancelCommand="doitemcancel" OnUpdateCommand="doitemupdate"
onEditCommand="doitemedit" PagerStyle-HorizontalAlign="Right" AllowPaging="true" PagerStyle-Mode="NumericPages"
PageSize="20" Runat="server">
<Columns>
    <asp:EditCommandColumn EditText="edit" CancelText="cancel" UpdateText="update" />
</Columns>
</asp:datagrid>

in this case i dont know how to hide this editcommandcolumn in runtime.

 2.this time i didn't declared columns in design time
        <asp:datagrid id="grd" AutoGenerateColumns="true" OnCancelCommand="doitemcancel" OnUpdateCommand="doitemupdate"
onEditCommand="doitemedit" PagerStyle-HorizontalAlign="Right" AllowPaging="true" PagerStyle-Mode="NumericPages"
PageSize="20" Runat="server">
</asp:datagrid>

  and runtime i created controle like

Protected x As New System.Web.UI.WebControls.EditCommandColumn

x.EditText = "edit"
grd.Columns(.add(x))

        but here problem is doitemedit(which declared in oneditcommand) method is not firing

pl help me how to do this.

thanks

Setup your datagrid in the ASPX file like this (note my bolded addition):

    <asp:datagrid id="grd" AutoGenerateColumns="true" OnCancelCommand="doitemcancel" OnUpdateCommand="doitemupdate"
onEditCommand="doitemedit" PagerStyle-HorizontalAlign="Right" AllowPaging="true" PagerStyle-Mode="NumericPages"
PageSize="20" Runat="server">
<Columns>
    <asp:EditCommandColumn EditText="edit" CancelText="cancel" UpdateText="update" Visible="False"/>
</Columns>
</asp:datagrid>

Then in your codebehind (you could put it in page load if you wanted to, or in the event handler for the checkbox):

grd.Columns(x).Visible = chk3.Checked
(where x is the proper column index number of your EditCommandColumn column.)

Now every time the page loads (or when you un/check the chk3), the visibility of that datagrid column will be set based on the status of the checkbox. Note that you need to ensure that the checkbox causes a postback so the datagrid is redrawn. You *shouldn't* need to rebind the datagrid however because the column is already there, it's just not visible.
