How to Add Edit Image

In the code behind, you can handle the click event of the Image control to perform the edit action

protected void imgEdit_Click(object sender, ImageClickEventArgs e)
{
    // Get the row where the edit button was clicked
    GridViewRow row = ((ImageButton)sender).NamingContainer as GridViewRow;
    
    // Retrieve the data from the row using row.FindControl("ControlID")
    string column1 = (row.FindControl("lblColumn1") as Label).Text;
    string column2 = (row.FindControl("lblColumn2") as Label).Text;
    string column3 = (row.FindControl("lblColumn3") as Label).Text;
    // ... and so on
    
    // Perform the edit action using the retrieved data
    // ...
}

In the GridView, the BoundFields should be replaced with the actual column names from your DataTable, and the control IDs in row.FindControl should match the IDs of the controls in the ItemTemplate.

To add an edit image after the last column in the GridView, you can use a TemplateField with an Image control that has a click event to handle the edit action. 

    
        
        
        
        
            
                <%# Eval("Remarks") %>
            
        
        
            
                <%# Eval("Date") %>
            
        
        
            
                
            
        
    

protected void grdPlanning_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Edit")
    {
        int rowIndex = Convert.ToInt32(e.CommandArgument);
        // perform edit operation
    }
}
