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
Thanks & regards

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,

Hi angel,
Thanks for the Reply. I would like to Thank you for the support that Yesteraday you Gave.
if Templating Means the Textfield and valueFields then yes I will be using the Same Templating.
and I have to Rebind the Values to the Dropdown Every time as My need Requires that. becoz when There is a Selection in the First Dropdown, based on which the second dropdownlist should Populate like the Cascading Dropdowns. (Fyi : I tried the Cascading sample which is there in the samples of 2009 but there also I am getting the same Problem. )
and I am using the UpdatePanel as discussed yesteraday in the Last post :
http://forums.infragistics.com/forums/p/25877/95076.aspx#95076
if possible please attach the sample with the updatepanel in which multiselection webdropdown placed as the First Dropdown and based on the selection of the First Dropdown fill the Seconddropdown which is a Normal webdropdown. all this should happen async...
