Hi Friends,

I am struck with one issue,that disabling of LinkButton in Gridview Control. I search in net,I could not find the solution.

The LinkButton in Gridview. For Each row there is linkbutton is displaying in GV.

Look likes :

XML

 <itemtemplate>
<asp:linkbutton id="lnk" runat="server" text="RunTheJob" command="lnk_Click" commandargument="<%# Eval(" val=")%>" xmlns:asp="#unknown" />        </itemtemplate>

In Code:

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow)
   { 
     LinkButton lnkMarkAsRerun =  
              (LinkButton)e.Row.FindControl("lnkMarkAsRerun");
     lnkMarkAsRerun.Attributes.Add("onclick", "return confirm('Are you 
               sure you want to update this task?');");

// Here i Need Logic.. When i Click the LinkButton,a confirm pop is display, if user  click "OK" then only LinkButton Need to Enable= False for Particular Row only.
   }
}

Please Help..

Instead of calling inline javascript confirm dialog, call a javascript function, accept the user selection and make linkbutton disable from javascript something like,

lbtn.disabled  =  confirm('Are you sure you want to update this task?');

I suggest you do

<br />
<br />
<asp:linkbutton id="link" runat="server" text="RnTheJob" xmlns:asp="#unknown"><br />
OnClientClick="return confirm('Are you sure you want go update this task?');"<br />
<br />
command = "lnk_Click" commandArgument="<%# Eval("val")%>" /><br />
<br />
</code></asp:linkbutton>

XML

<asp:LinkButton id="link" runat="server" text="RnTheJob" xmlns:asp="#unknown" OnClientClick="return ToggleEnable(this);"
command = "lnk_Click" commandArgument="<%# Eval("val")%>" />

and write a JavaScript function,

JavaScript

function ToggleEnable(src)
{
var result = confirm('Are you sure you want to update this task?');
src.disabled = result;
return result;
}

You can remove the return false statement if you want it to Postback.

as per the question I believe a small change is needed

function ToggleEnable(src)
{
if(confirm('Are you sure you want to update this task?'))
{
src.disabled = 'false';
}
else
{
src.disabled = 'true';
}
}

@senguptaamlan: as per the question, the user want to disable the LinkButton on clicking OK.

So,
src.disabled = confirm('Are you sure you want to update this task?');

should be fine. Please read the question again (if required) to clarify yourself.

Hi Venkatesh, your logic working fine. I need to smalll changes,When click on LinkButton it disable,and run "Job" or "Query" and reflected in database.. But Not Happening now, when i click "Cancel" of pop window.. it updating...
It should update when i click "OK" and Linkbutton should disable..

Hi Venkatesh

oh, still not working...
In called the javascript like this
LinkButton.Attributes.Add("onclick", "LinkEnable(this);");
in Griview -->GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
in disabling, but i have LinkButton_Click() event, where i will do database operation, but not firing... how to enable the LinkButton_Click()

Once the button is disabled, it will not trigger the Postback. What you can do is mouse over LinkButton on runtime, your might see something like "__Postback('LinkButton1','');". You have to add this line to the LinkEnable() function.
