posted

Hi all,

I trying to Use a Webdropdown.  when i am Trying to Bind the Control with the Datatable setting its TextField and Value Field , it is showing the Values For the First Time and From the Next time it is Showing empty Text and Value though I am able to List items it is showing Empty Text.

 

it would be Great if you can Even Help me with this. My work would be almost Done.

 

 

FYI

  protected void WebDropDown1_ValueChanged(object sender, Infragistics.Web.UI.ListControls.DropDownValueChangedEventArgs e)
    {

 

WebDropDown2.Items.Clear();

            DataTable dt = new DataTable();

            dt.Columns.Add("name", typeof(string));
            dt.Columns.Add("id", typeof(int));

            DataRow dr = dt.NewRow();
            dr["name"] = Convert.ToString("test" + DateTime.Now.ToString());
            dr["id"] = Convert.ToInt32(1);

            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr["name"] = Convert.ToString("test12" + DateTime.Now.ToString());
            dr["id"] = Convert.ToInt32(1);

            dt.Rows.Add(dr);

            WebDropDown2.DataSource = dt;
            WebDropDown2.TextField = "name";
            WebDropDown2.ValueField = "id";
            WebDropDown2.DataBind();





            DIV1.Controls.Add(WebDropDown2);

 


    }

 

For the First time It is showing the Value but for the next it is Showing. Please do the needful

    Hello,

    This code works fine for me. But why would you want to rebind the items list in the ValueChanged event ? 

    Do you use some templating as well ? 

    Best,
