Custom Server Control - Button Click Event

Question

I cannot get the button event inside my custom server control to raise. Below is an example written in 3.5. I believe my events are in order from examples listed online. Any help?

[ToolboxData("<{0}:TestButton runat=server></{0}:TestButton>")]public class TestButton : WebControl

{

public Button Tester { get; set; }

public Label ClickedIndicator { get; set; }

protected override void CreateChildControls()
{
   base.CreateChildControls();

   Tester = new Button();
   Tester.ID = "btnTest";
   Tester.Text = "Increment Count";   Tester.Click += new EventHandler(Tester_Click);
   this.Controls.Add(Tester);

   ClickedIndicator = new Label();
   ClickedIndicator.ID = "lblClickCount";
   ClickedIndicator.Text = "not clicked";
   this.Controls.Add(ClickedIndicator);
}

protected void Tester_Click(object sender, EventArgs e)
{
   ClickedIndicator.Text = "clicked";
}

Hi,

You can use Acceptchange() method after deleting code. Just check this.
Change the table name as per ur TableName.
Insted of session You can use direct table from DataAdapter. Just assign table name. Check this code...

Write this code in GridView1 RowDelete Command event.

protected void GridView1_RowDeleted(object sender, GridViewDeletedEventArgs e)
    {      
        int i;       
        DataSet objds = (DataSet)Session["ObjDataSet"];     //Assign table from database here.
        DataTable dtNewAct = (DataTable)objds.Tables[0];
        i = GridView1.SelectedIndex;
        for (int iRow = 0; iRow < objds.Tables[0].Rows.Count - 1; iRow++)
        {
            if (i == iRow)
            {
                if (objds.Tables[0].Rows[i].RowState != DataRowState.Deleted)
                {
                    objds.Tables[0].Rows[i].Delete();
                    objds.Tables[0].AcceptChanges();
                    Session["ObjDataSet"] = objds;
                }
            }
        }

    }

Add following line after your delete logic :
sqllAdap.Update(ds.Tables[TBL_NAME]);
