How to display server-side variables in an alert using JavaScript in ASP.NET

I need to display a server-side variable in a JavaScript alert.

 <asp:Button id="btnDelete" runat="server" class="deleteicon" Text='<%# Eval("iuser_id") %>' OnClick="deleteclick" onclientclick="return confirm('Are you sure you want to delete this record?'+<%# Eval("struser_name") %>);"/>

This button is used for deleting records within a gridview. When clicked, I want to show an alert with user confirmation and the name of the user being deleted. However, I am encountering a server tag formatting error.

Appreciate any assistance,

Answer №1

REVISED

To incorporate a JavaScript click function in the rowDataBound event of the gridview, follow this safest and most straightforward approach. The code is outlined below.

protected void GridView1_RowDataBond(object source, GridViewRowEventArgs e) 
    { 
        if (e.Row.RowType == DataControlRowType.DataRow) 
        { 
            Button btnAlertStatus = (Button)e.Row.FindControl("btnAlertStatus"); 

            DataRowView drv = (DataRowView)e.Row.DataItem; 

            string username = drv["User_name"].ToString(); 

            btnAlertStatus.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this record?"+ username + "')"); //error due to missing bracket in JavaScript
        } 
    }

UPDATED

Consider implementing the following JavaScript function:

function confirmMsg()
{

  var Variable = '<%= ServerVaraible %>';
  return confirm('Are you sure you want to delete this record?'+ Variable );
}

Include the following HTML element:

 <asp:Button id="btnDelete" runat="server" class="deleteicon" Text='<%# Eval("iuser_id") %>' OnClick="deleteclick" onclientclick="return confirmMsg();"/>

Answer №2

 <asp:Button id="btnDelete" runat="server" class="deleteicon" Text='<%# Eval("userid") %>' OnClick="deleteEntry" onclientclick='return confirm("Are you certain you wish to remove this item? <%# Eval("username") %>");'/>

Update: Try using different types of quotations
