Controls disabled after RadComboBox postback

Every time my code executes the selected index changed event for a radcombo box, all other controls on my page become disables temporarily. If I try to type in any of the controls on my page rigth after the selected index changed event, nothing happens until i click anywhere on the form and then back on the control. Below is my selected index changed event code:

if

(e.Value != string.Empty)

{

txtItemDescription.Text =

string.Empty;

hdnItemNumber.Value = e.Value;

if (e.Value != string.Empty)

{

foreach (DataRow dr in GetItem(e.Value.Trim()).Rows)

{

txtItemDescription.Text = dr[

"Description"].ToString();

break;

}

}

Here is my ASP.NET code:

<

table border="0" cellpadding="2">

<tr>

<asp:HiddenField ID="hdnItemMode" runat="server" />

Item Number:

</td>

<telerik:RadComboBox runat="server" ID="rcbItemNumber" AllowCustomText="True" EnableItemCaching="True"

EnableLoadOnDemand="True" EnableVirtualScrolling="True" OnSelectedIndexChanged="rcbItemNumber2_SelectedIndexChanged"

DataTextField="ItemNumber" DataValueField="ItemNumber" OnItemsRequested="rcbItemNumber_ItemsRequested"

MaxHeight="180px" CausesValidation="false" ShowMoreResultsBox="True" ShowWhileLoading="False"

AutoPostBack="True">

</telerik:RadComboBox>

<asp:HiddenField ID="hdnItemNumber" runat="server" Value='<%# Bind("ItemNumber") %>' />

<asp:Label ID="lblItemsFound" runat="server" ForeColor="Red"></asp:Label>

</td>

Description:

</td>

<asp:TextBox class="textbox" ID="txtItemDescription" Width="250px" Text='<%# Bind( "ItemDescription") %>'

TextMode="MultiLine" Rows="4" runat="server"></asp:TextBox>

</td>

</tr>

< tr>

<td>

Qty:

</td>

<td>

<asp:TextBox class="textbox" ID="txtQty" Width="150px" runat="server"></asp:TextBox>

</td>

<td>

Price:

</td>

<asp:TextBox ID="txtPrice" runat="server" class="textbox" Width="150px"></asp:TextBox>

</td>

</tr>

</table>

Loading ascx controls in placeholder

Hi,
     I am using .Net 3.5 version.I am using RadMenuControl, for every click on menu items it was loading usercontrols in the default.aspx, In Default.aspx i am placing placeholder in that place holder loading ascx controls.I am placing asp update panel for that place holder.
                                    Default.aspx
                                    <asp:Updatepanel >
                                                <asp:PlaceHolder>
                                           control1.ascx
                                            Control2.ascx
                                            Control3.ascx

   I am able to load the controls,but the script was always loading first control.when i view the viewsource it was always showing first page(Control1.ascx). If i remove the asp update panel it was working.My requirement is loading controls with partial post back.

Cross Browser Testing - Multiple Issues

Hi

I am currently in the process of evaluating the Telerik Editor control for use in a web application which needs to run on multiple web browsers on both PC and Mac. To test the control we created a number of simple tests which were performed on each of the target platforms.

I have attached a document which lists these tests and the issues which we encountered. Can someone comment on these issues and whether or not there are any workarounds or plans to fix the problems in any up-coming releases (with release dates if possible) ?

Thanks

How To Serialize Data Within RadGrid To XML Using RadGrid's Server Side API

Hello,
I have a need to seriaize data from a RadGrid's data into XML for storage into a database field and am having trouble determining how to do this.

Example: Imagine that you have classes for entities like People, Places, etc. that all have different types and numbers of properties and you want to serialize them to a common XML format that is "original class agnostic" and is basically just a generic representation of a collection in XML format. Basically I have a scenario where I read data from a set of tables to populate a RadGrid with dynamically generated columns (the columns are dependent on which table the data is loaded from), then the user can add new rows and edit the existing data, then I need to save all the data that is currently in the RadGrid including the order of the rows/items into 1 field of data (e.g. one XML string that is saved to a DB field)

Using the following data as an example:

[First Name] [Last Name] [Age]
John Smith 34

Jane                 Smith               35

[Address]          [City]          [State]          [Postal Code]
123 Help St.       Chicago      IL                 60652

How could I use the RadGrid's API to serialize both types data (Person and Address) in the same way so the items are generically stored in XML as objects that can be deserialized into RadGrid items/rows and column values again later?

Sys.WebForms.PageRequestManager null or not an object

I have a radlistbox on a page and when the page loads I get this javascript error:

Sys.WebForms.PageRequestManager is null or not an object

Here is the page code:

<

telerik:RadScriptManager ID="RadScriptManager1" runat="server" />

<

telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1">

Player Name:

 <telerik:RadTextBox ID="radtxtAddPlayer" MaxLength="110" runat="server" /><asp:Button ID="btnAddPlayer" OnClick="btnAddPlayer_Click" Text="Add Player" runat="server" />

<

telerik:RadListBox ID="radlstPlayerPosition"

runat="server" height="300px" width="150px"

DataTextField="PlayerName" DataValueField="nPlayerID" AllowDelete="true"

AllowReorder="true" AllowTransfer="false" AutoPostBack="True">

</telerik:RadListBox>

</

telerik:RadAjaxPanel>

Any ideas why I would get this error? adding a player works even with the error there???

RadGrid and RowClick

Hello,

I have a RadGrid:

<tel:RadGrid ID="MG" runat="server">
   <MasterTableView DataKeyNames="Key" AutoGenerateColumns="false"
       Width="450px">
       <Columns>
           <tel:GridTemplateColumn HeaderText="Subject">
               <ItemTemplate>
                   <a href='<%# Url.Action("Select", "Messages", new { message = DataBinder.Eval(Container.DataItem, "Key") }) %>'><%# Eval("Subject") %></a>
               </ItemTemplate>
           </tel:GridTemplateColumn>
           <tel:GridBoundColumn HeaderText="Subject" DataField="Subject" />
           <tel:GridBoundColumn HeaderText="Sent" DataField="CreatedDate" DataFormatString="{0:MM/dd/yyyy}" />
           <tel:GridBoundColumn HeaderText="Last Reply" DataField="LastReply" />
           <tel:GridBoundColumn HeaderText="Reply Date" DataField="ReplyDate" />
       </Columns>
   </MasterTableView>
   <ClientSettings EnableRowHoverStyle="true">
       <ClientEvents OnRowClick="MG_RowClick" />
       <Selecting AllowRowSelect="true" />
   </ClientSettings>
</tel:RadGrid>

The MG_RowClick event never fires in my MVC view. The script is in the same place as my MVC view...   SelectedIndexChanged doesn't fire either.

How do I get that to work?

Thanks.

Recursively expand groups

Hello,

I have a grid setup with multiple groups. The groups are year, month and day. By default, all groups should be closed except the one of todays date, that one should be expanded.

I've got the code to retrieve the GridGroupHeaderItem object for the group which matches todays date (year-month-day), and I can expand that. But I need all of the above groups (year, month) to be expanded as well. What is a good way of traversing up the group hierarchy to expand all groups above? I would like to make this function recursive so I can use it again some other time, so it ideally shouldn't be fixed to a number of parent levels.

Adding a ProgressArea

Hi Folks,

Is it me or should this be simple? I just want to add a progressarea like in the Telerik examples. When I first added it to my project I got the error about it not being registered in the config file, so I put these lines in:

    
            <httpHandlers> 
        
                    <add path="Telerik.RadUploadProgressHandler.ashx" validate="false" verb="*" type="Telerik.Web.UI.RadUploadProgressHandler"/> 
        
                  </httpHandlers> 
        
                  <httpModules> 
        
                    <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule"/> 
        
                  </httpModules>

Now it doesn't throw any error but doesn't actually do anything when I upload a document! Is there a step-by-step guide of how to add a progressarea properly?

Thanks,
IW
