In a gridview, can I programatically control display of edit/delete buttons for selected row?

Hi there,

I'm sure this is something fairly straight forward but I'm only just getting used to working with gridviews so please help me,

I am displaying the select button on my gridview, and on the SelectedIndexChanged event I would like to add (or make visible) the edit and delete buttons just for the selected row - can I do this?

 All help appreciated,

 First thing if you are using asp:commandfield than my solution will not work, but my suggestion is that instead of commandfield use asp:TemplateField, and put link button inside that.

On the RowDataBound Event of gridview find that linkbutton and make visible = false like :

LinkButton temp = (LinkButton)e.Row.Cells[X].FindControl("linkbutton");

temp.visible = false.

and same case you reverse at the SelectedIndexChange event of GridView like this :

LinkButton temp = (LinkButton)GridView1.Row[GridView1.SelectedIndex].Cells[X].FindControl("linkbutton");

temp.visible =  true;

That's it.

Note: "linkbutton" is id of your link button inside gridview template field, and 'X' is cell no of your GridView. 

Hope this might solve your problem.

Happy Programming.

Hi Jay,

Thanks for your help - I've got partial success with it!

I am using a template field, and I make the edit and delete linkButtons non-visible by default in the template definition.

Using your approach to make them visible in the SelectedIndexChanged event then works great using :

LinkButton editLinkButton = (LinkButton)GridView1.SelectedRow.FindControl("editLinkButton");


However, switching the edit and delete buttons off again is proving more problematic - your suggestion of doing it in the rowDataBound event gave me an error:

 Object reference not set to an instance of an object.

So I guess I need to find another suitable point to set visible=false - any suggestions?

  Try this:

 protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
        foreach (GridViewRow r in this.GridView2.Rows) {
            if (r != this.GridView2.SelectedRow)
                r.FindControl("Button1").Visible = false;
            else r.FindControl("Button1").Visible = true;

             <asp:GridView AutoGenerateSelectButton="true" ID="GridView2" runat="server" DataSourceID="SqlDataSource1" OnRowDataBound="GridView2_RowDataBound" OnSelectedIndexChanged="GridView2_SelectedIndexChanged">
               <asp:Button ID="Button1" runat="server" Text="Edit" CommandName="Edit" Visible="false" />

If it doesn't work, please inform us.
