TextBox and Radcombobox problem

[Dilip]

Hi,
   I have a textbox and radcombobox control on a page. The textbox is for zip codes and the radcombo should autocomplete the stores in a zip as i type in the combobox. When i type in some text in combobox it does not seem to take the text I passed in textbox control initially. But if i comeback and change the text in zip textbox (basically enter the same text again) it seems to populate the combobox as expected.  Not sure if I a missing anything. Can someone help me with this please.


Thanks
Dilip

Here is my aspx code for this part.

<tr>

 

 

<td style="width: 40%; height: 26px;">

 

 

<div class="pagecontentalt">Zip</div></td>

 

 

<td style=" height: 26px">

 

 

<asp:TextBox ID="txtZip" runat="server"></asp:TextBox></td>

 

 

</tr>

 

 

<tr>

 

 

<td style="width: 40%">

 

 

<div class="pagecontentalt">Stores</div></td>

 

 

<td>

 

 

<telerik1:RadComboBox ID="rdComboSCT" runat="server"

 

 

AllowCustomText="True" ShowToggleImage="False"

 

 

EnableLoadOnDemand="True"

 

 

OnItemsRequested="rdComboSCT_ItemsRequested"

 

 

Skin="Web20"

 

 

AutoPostBack="True" onselectedindexchanged="rdComboSCT_SelectedIndexChanged"

 

 

ShowWhileLoading="True">

 

 

 

</telerik1:RadComboBox></td>

 

 

</tr>



Hers is part of  my code behind. 

 

 

protected void rdComboSCT_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

 

{

 

RadComboBox comboBox = (RadComboBox)sender;

 

BindDataToSCTComboBox(e.Text, comboBox);

}

 

 

protected void BindDataToSCTComboBox(string text, RadComboBox comboBox)

 

{

 

DataTable dt = new DataTable();

 

dt =

new ProjDataHandler().GetItemsLikeForZipAsDataTable(text, txtZip.Text.Trim());

 

 

comboBox.Items.Clear();

 

foreach (DataRow row in dt.Rows)

 

{

 

RadComboBoxItem item = new RadComboBoxItem();

 

item.Text = row[

"Name"].ToString();

 

item.Value = row[

"Id"].ToString();

 

comboBox.Items.Add(item);

}

}

Hi Dilip,

Thank you for the provided cove.

The reason for the problem is that ItemsRequested event is a result of a callback. And when it is executed the ViewState is not loaded yet.

I suggest you solve the problem by using the Context property of RadComboBox. Please follow the article for more details : Passing Context Information to the Server
