Updating items inside of an edit template

I'm sure the answer is out there, but my searches have not turned it up. Currently I have a RadGrid with a details table below it. Inside of that details table I have an EditFormsSettings.

<EditFormSettings EditFormType="Template">

<FormTemplate>

Select from combobox: <telerik:RadComboBox ID="ComboBox1" runat="server"

DataSourceID="edsSource" AutoPostBack="true"
OnSelectedIndexChanged="ComboBox1_SelectedIndexChanged"

DataTextField="Name" DataValueField="Id" />

<br />

Label: <asp:Label ID="Label1" runat="server" />

</FormTemplate>

</EditFormSettings>

Currently it loads fine, because I have the event on the main grid ItemDataBound look for a GridEditableItem and updates it appropriately.

What I want to do is whenever the SelectedIndex Changes on the combo box, I want to update the label inside of that edit template. How can i do this?

Thanks

Client side code "click"

Hello,

We need to simulate node click event on client side. We tried to use client side select() method, but this method does not cause postback, like expand() method for example.

Is there client side method that equivalent to user click action? Or may be there is a workaround for the problem?

Regards,
Olga

Problem with embedded RadListView

We have the following code. At first we attempted to use a RadDataPager for the paging but the paging wasnt working. So i added asp buttons to see what is occuring the following error is returned:

Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Parameter name: element

I think the problem is that this RadListView is embedded within another RadListView (and some other server controls) further up the page. How can we get an embedded RadListView like this to page correctly?

Code is below.

Thanks

<asp:Panel ID="pnlMultiImagePreview" runat="server" Visible="false">

<asp:UpdatePanel ID="upMultiImagePreview" runat="server">

<ContentTemplate>

<telerik:RadListView ID="rlvMultiImagePreview" runat="server" DataKeyNames="PreviewImage" AllowPaging="true" ItemPlaceholderID="ImagesContainer" PageSize="1" >

<ItemTemplate>

<asp:Panel ID="pnlMultiImagePage" runat="server">

<asp:Image ID="imgMultiThumb" runat="server" ImageUrl='<%#Eval("PreviewImage")%>' CssClass="previewImage" />

</asp:Panel>

</ItemTemplate>

<LayoutTemplate>

<!-- Set the id of the wrapping container to match the CLIENT ID of the RadListView control to display the ajax loading panel           In case the listview is embedded in another server control, you will need to append the id of that server control -->

<fieldset id="rlvMultiImagePreview">

<legend>Images</legend>

<asp:PlaceHolder ID="ImagesContainer" runat="server" />

<div style="padding-left: 20%;">

<asp:Button runat="server" ID="btnFirst" CommandName="Page" CommandArgument="First"

Text="First" Enabled="<%#Container.CurrentPageIndex > 0 %>" />

<asp:Button runat="server" ID="btnPrev" CommandName="Page" CommandArgument="Prev"

Text="Prev" Enabled="<%#Container.CurrentPageIndex > 0 %>" />

<span style="vertical-align: top; position: relative; top: 4px">Page <%#Container.CurrentPageIndex + 1 %> of <%#Container.PageCount%> </span>

<asp:Button runat="server" ID="btnNext" CommandName="Page" CommandArgument="Next"

Text="Next" Enabled="<%#Container.CurrentPageIndex + 1 < Container.PageCount %>" />

<asp:Button runat="server" ID="btnLast" CommandName="Page" CommandArgument="Last"

Text="Last" Enabled="<%#Container.CurrentPageIndex + 1 < Container.PageCount %>" />

<br />

</div>

<div id="itemPlaceHolder" runat="server">

</div>

Flashing cursor in Combo box

I have a combo box when the pull down is active for the selection, there is a flashing 'I' curson in the input field which implies that you can type in there - which you cant. I have set the Selectable value to false which is meant to stop people being able to select the content of the combo box (the 'I' tool is used to do that), but it remains selectable.

I have tried modifying the CSS to hide the cursor but that ofly affects the mouse over.
We are using Q42009.

Any ideas.

RadDock Default Commands not displaying correctly

Hi,

I am dynamically creating raddocks server-side. Everything works perfectly in debugging mode, but as soon as i deploy to a remote server then the raddocks command buttons (close and expandcollapse) disappear. I am using IE8 to test the remote webpage.
However, if I use Chrome to test the remote page it all works as expected.

I am using XHTML 1.0 doctype and 2010 Q1 SP1

What do i need to take a look at to solve this problem?

Thanks,

Garth

My silverlight control (WCF?) stops working when enabling RadCompression.

Hello,

I have an ASP.NET solution that instantiates a silverlight control, I feed data into this control through WCF.

When ever I add the following* lines into the web.config my silverlight control stops working (doesn't display the data).
I've tried debugging with fiddler and get the following error** when calling WCF.

Error**

Fiddler has detected a protocol violation in session #13.

Content-Length mismatch: Response Header indicated 2,182 bytes, but server sent 527 bytes.

If I remove the below entries from the web.config then the error goes away.

Web.Config*

<

httpModules>

<

add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule" />

<

add name="RadCompression" type="Telerik.Web.UI.RadCompression" /></httpModules>

</

system.web>

Any thoughts? Suggestions?
Thanks

How do I detect a grid size change?

I am wondering how I detect that my grid has changed size, horizontally.

I have a grid that is defined as 100% of the width of its containing element.

Which is a RadDock.

I would like to react to size changes, so I can alter the contents of the CommandItem
to fit.

TIA

RadEditor Flashes White background When Submit Button Clicked

I have read several posts on related problems, but I could not find a solution to this particular problem.
RadEditor sets the background for the control properly based on the RadSkin=Black setting in web.config.

However, when I click my Submit button to save the contents of the area and a separate TextBox, the background color in the RadEditor changes to white momentarily and then returns to the body color from the page. I want to prevent the white flashing.

Any help would be greatly appreciated.

Accessing RadGrid entity datasource's field values in code behind

This seems like it should be a straight forward thing to do, but it's eluding me, and I've searched for an answer. Hopefully I'm overlooking something simple.

I'm binding my RadGrid to an entity data source. I'm using GridTemplateColumn columns for many of the columns, as I combine several of the data fields into one column. How do I access the RadGrid datasource's field values (in the code-behind)? This is in non-edit, regular view of the grid.

For example, I'd like to do something like this:

protected void ContactsGrid_ItemDataBound(object sender, GridItemEventArgs e)

{

if ((!e.Item.IsInEditMode) && (e.Item is GridDataItem))

{

GridDataItem dataItem = (GridDataItem)e.Item;

// Assuming my entity data source has a field named "dataFieldName", would be nice to access:

string dataFieldValue = (string)dataItem("dataFieldName"

).Value; 


        // Would then find the GridTemplateColumn in order to fill in the ItemTemplate, 

        // which already know how to do...

}

Thanks,
Steve
