RowCommand not getting executed

Ramco Ramco

I have below code but RowCommand not getting executed

protected void grdPlanning_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            try
            {
                
                    BALBooks bALBooks = new BALBooks();
                    BALStudents bALStudents = new BALStudents();
                    StudentDetail Result = bALStudents.GetStudentDetailByLoginID(bALStudents.GetStudentIDByMobile(hdfMobile.Value));
                    ltrlHead.Text = Result.Name;
                    ltrlHead.Text = ltrlHead.Text + " : " + bALBooks.GetBookTitle(Convert.ToInt32(hdfBookId.Value));

                    BindData(Convert.ToInt32(hdfBookId.Value), Result.LoginCode);
                
            }
            catch (Exception ex)
            {
                Utility.SaveErrorLog(ex.Message, System.IO.Path.GetFileName(Request.Path), System.Reflection.MethodBase.GetCurrentMethod().Name, Convert.ToInt32(hdfLoginCode.Value));
                ShowMessage("Oops...", ex.Message, "error");
            }
        }

protected void gr_RowDataBound(object sender, GridViewRowEventArgs e)
{
    try
    {
        if (e.Row.RowType != DataControlRowType.DataRow)
            return;
        e.Row.Cells[0].HorizontalAlign = HorizontalAlign.Center;
        for (int i = 8; i < e.Row.Cells.Count - 1; i++)
        {
            string cellValue = e.Row.Cells[i].Text;
            var row = (DataRowView)e.Row.DataItem;
            var currentPerson = row[0].ToString();
            var currentDate = row.DataView.Table.Columns[i];
            var commandArgument = currentPerson + ":" + currentDate;

            LinkButton button = new LinkButton();
            button.Text = cellValue;
            button.CommandName = "Select";
            button.CommandArgument = commandArgument;
            button.OnClientClick = "GetModuleData(this)";


            if (cellValue.ToUpper().Trim() == "A")
            {
                button.CssClass = "badge badge-danger";
            }
        }
    }
}

Thanks

Hi Ramco try this.
1. Remove the OnRowCommand="grdPlanning_RowCommand" attribute from the GridView markup. This will detach the event handler from the RowCommand event.
2. Add the RowCommand event handler programmatically in the code-behind file (Page_Load or OnInit event). Here's an example:
3. protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { grdPlanning.RowCommand += new GridViewCommandEventHandler(grdPlanning_RowCommand); } }
  
  Make sure to replace Page_Load with the appropriate event handler method if you're using a different event.
4. Modify your grdPlanning_RowCommand method to match the correct delegate signature:
5. protected void grdPlanning_RowCommand(object sender, GridViewCommandEventArgs e) { // Your code here }

Hi Mohammed

protected void grdPlanning_RowCommand(object sender, GridViewCommandEventArgs e)
{

}

Kindly check this once in your code
```
protected void grdPlanning_RowCommand(object sender, GridViewCommandEventArgs e)
{
    // Your code here
}
```
Make sure that the method has the (object sender, GridViewCommandEventArgs e) parameters and that it is declared as protected. Also, confirm that it is not declared as static or has any additional parameters.

Hope this resolves the error

Hi Mohammed

It is giving error - No OverLoad for grdPlanning_RowCommand matched delegate eventHandler

In the provided code, the RowCommand event of the GridView is not getting executed because the LinkButton in each row is missing the OnClick event handler attribute. The OnClick attribute is necessary for the LinkButton to trigger the RowCommand event when clicked.

To fix this, modify the code inside the gr_RowDataBound method as follows:
```
LinkButton button = new LinkButton();
button.Text = cellValue;
button.CommandName = "Select";
button.CommandArgument = commandArgument;
button.OnClientClick = "GetModuleData(this)";
button.Click += new EventHandler(grdPlanning_RowCommand); // Add this line

if (cellValue.ToUpper().Trim() == "A")
{
    button.CssClass = "badge badge-danger";
}

e.Row.Cells[i].Controls.Add(button); // Add this line
```
With these modifications, the LinkButton will have an OnClick event handler that references the grdPlanning_RowCommand method. The RowCommand event will be triggered when the LinkButton is clicked, and the code inside the grdPlanning_RowCommand method will execute.

Make sure to add these modifications and retest your code. The RowCommand event should now be triggered properly.
