disable OnClientClick when LinkButton is disabled

In my gridview, I have included a column containing a LinkButton that allows you to delete the record on the same row where the LinkButton is :

<asp:TemplateField HeaderText="">
     <ItemTemplate>
          <asp:LinkButton ID="lnkDeleteTxn" Text="Delete" runat="server" CommandArgument='<%# Eval("TxnID") %>' OnClick="deleteTxn" 
          OnClientClick="return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?');"></asp:LinkButton>
     </ItemTemplate>
</asp:TemplateField>

This LinkButton includes showing a pop-up window asking if the user really wants to delete the record. Now, for my RowDataBound event, I set it so that whenever the Status of the Record is "Approved", the Delete LinkButton is disabled:

string recStatus = Convert.ToString(DataBinder.Eval(e.Row.DataItem,"StatusDesc"));
if (recStatus == "Approved")
{
    hlTxnEdit.Enabled = false;
    lnkTxnDelete.Enabled = false;
}
else
{
    hlTxnEdit.Enabled = true;
    lnkTxnDelete.Enabled = true;
    //lnkTxnDelete.Attributes.Add("OnClientClick", "return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?')");
}

the problem is, when the user clicks on the disabled LinkButton, the confirmation pop-up still displays, when it should not, because the LinkButton is disabled. Makes a bit of sense, because the Attribute where the pop-up window is set is on the OnClientClick attribute. How do I make the pop-up window not show up? I tried adding the OnClientClick attribute in the code behind, but it doesn't work. The LinkButton proceeds straight on deleting the record.

You can fix the issue in these steps.

  1. Remove the OnClientClick from Declaration html.

  2. On GridView OnDataRowBound event handler in the code behind add this OnClientClick 

    lnkTxnDelete.Attributes.Add("OnClientClick", "return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?')");

  3. Make sure you are adding this code only when recStatus <> "Approved".

Make change in your aspx as below...

<asp:TemplateField HeaderText="">
    <ItemTemplate>
        <asp:LinkButton ID="lnkDeleteTxn" Text="Delete" runat="server" CommandArgument='<%# Eval("TxnID") %>' OnClick="deleteTxn"></asp:LinkButton>
    </ItemTemplate>
</asp:TemplateField>

Add your confirmation pop-up from the code behind like this.

string recStatus = Convert.ToString(DataBinder.Eval(e.Row.DataItem,"StatusDesc"));
if (recStatus == "Approved")
{
    hlTxnEdit.Enabled = false;
    lnkTxnDelete.Enabled = false;
    lnkTxnDelete.Attributes.Add("onclick", "return false;");
}
else
{
    hlTxnEdit.Enabled = true;
    lnkTxnDelete.Enabled = true;
    lnkTxnDelete.Attributes.Add("onclick", "return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?')");
}

if (recStatus == "Approved")
 {
    hlTxnEdit.Enabled = false;
    lnkTxnDelete.onClientClick = null;//

 }
 else
  {

    hlTxnEdit.Enabled = true;
    lnkTxnDelete.Enabled = true;
    //lnkTxnDelete.Attributes.Add("OnClientClick", "return confirm('!!--WARNING--!! You are about to delete the transaction. Performing this action will permanently remove the transaction and all its details from the database. Proceed?')");
  }

Rather than defining the OnClientClick attribute in template field. Add the OnClientClick attribute on your RowDataBound event when status is Approved.

lnkButton.Attributes.Add("OnClientClick","Javascript");
