Hello

I have a GridView bound to a SqlDataSource and would like to try and set the visibility of a LinkButton based on the value of column in that row for example:

If Column ACTION_STATUS is 12 (Closed) then I want to hide the LinkButton I know I should be able to use the LinkButton.Visible = false; to do this, but not sure how to check the value of ACTION_STATUS

I want to be able to handle all this in the code behind page too.

As ever any help would be most appreicated.

Thanks

Pete

hi,
Please Use Following Steps
1. make Change your sql query for ACTION_STATUS condition. use Case Switch for check condition. when value is 12 then return false

Case when ACTION_STATUS='12' Then 'false' else 'True' End as ACTION_STATUS

2. In Design View
<asp:HyperLink ID="hplUR" runat="server" Text='ur text' Enabled='<%# Eval("ACTION_STATUS")%>' ></asp:HyperLink>
no need to RowDataBound event for that.

:thumbsup:

Hi it's very simple where e.Row.Cells[0] is index of your ACTION_STATUS clumn

C#

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
        {
            if ((Convert.ToInt32(e.Row.Cells[0].ToString()) == 12))
            {
                HyperLink hy = (HyperLink)e.Row.FindControl("HyperLink");
                hy.Visible = false;
            }
        }

Please do let me know, if you have any doubt.

e.Row.cell["ACTION_STATUS"].Text == "12" FTFY :)

Please update
if (Convert.ToInt32(e.Row.cell["ACTION_STATUS"].Text) == 12)

Hi Imdadhusen

I tried as you suggested but get a red underline under the cell entry and then the following error:

'System.Web.UI.WebControls.GridViewRow' does not contain a definition for 'cell' and no extension method 'cell' accepting a first argument of type 'System.Web.UI.WebControls.GridViewRow' could be found (are you missing a using directive or an assembly reference?)

I would appreciate if you could offer any further help.

Thanks for the speedy answer.

This is syntax error because i didn't copy it from editor, i had written it directly in Answer box.
You should resolve the syntax error by yourself.

Anyway, Please find my updated reply

Hi,

First you need to find the link button is there in which column.

Then after finding,mention that cell no in row databound event as follows.

C#

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
        {
            if ((Convert.ToInt32(e.Row.Cells[0].ToString()) == 12))
            {
                HyperLink hy = (HyperLink)e.Row.FindControl("HyperLink");
                hy.Visible = false;
            }
        }

If you are still getting error, please check code for index position of linkbutton cell or where you are calling row databound event of Gridview.
