I have been digging through the help and could not find a solution.
I need to select a row server side based on the ID. The following piece of code does not find the item:
if (Session["selID"] != null)
{
GridDataItem item = RadGrid1.MasterTableView.FindItemByKeyValue("Container_ID", Session["selID"].ToString());
item.Selected = true;
Session["selID"] = null;
}
So I'm using the following method
if (Session["selID"] != null)
{
foreach (GridItem item in RadGrid1.MasterTableView.Items)
{
if (item is GridDataItem)
{
GridDataItem dataItem = (GridDataItem)item;
if (Session["selID"].ToString().Equals(dataItem.OwnerTableView.DataKeyValues[dataItem.ItemIndex]["Container_ID"].ToString()))
{
dataItem.Selected = true;
Session["selID"] = null;
break;
}
}
}
}
Somehow I feel that there has to be a better way to do it. I will appreciate if you could please suggest the optimum way.
Thanks

I am wanting to expand the parent node after I add a child node using the "PerformInsert" command. Currently the child does get added but is not visible since the parent is collapsed.

I have a Radio Button in header template of Rad grid columns. When user selects the radiobutton that particular column should be highlighted remaining should be greyed out.
<telerik:GridTemplateColumn DataField="BR" UniqueName="BR" HeaderStyle-Font-Bold="true" DataType="System.Double" HeaderText="BR" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
<HeaderTemplate>
<asp:RadioButton ID="rbBR" Text="Board Repair" runat="server" OnCheckedChanged="rbBR_CheckedChanged" AutoPostBack="true" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="lbBR" runat="server" Text= '<%# DataBinder.Eval(Container.DataItem,"BR") %>'></asp:Label>
</ItemTemplate>
</telerik:GridTemplateColumn>
Please let me know how to accomplish this.

I have a page with a master page in a C# 4.0 Web app (Visual Studio 2012.)
From my reading I am aware that there are potential problems in making a RadSplitter fill a page.
This page consists of 3 horizontal sections on the left and one vertical one on the right.
Up till now this page has been operated using Javascript to expose/hide controls and expand/collapse the RadPaneForm control.
Basically, the expand/collapse of RadPaneForm needs to be controlled by a RadComboBox in the center left section of the splitter.
I've been trying to 'Ajax-ify' the splitter in order to replace the JavaScript with code-behind C#.
(And for once I've had the time and ability to boil the problem down to a demo. Here it is.
The page has no code-behind in either the master page or the TestPage. Note that there are two RadComboBoxes in Panel1.
The problem is as follows: The splitter displays at half page height unless I remove one of the RadComboBoxes. Then it displays at full height.

Hello,
I tried to create the columns on the radgrid dynamically on Page_load (I can't create them on page_init)
I followed the instructions on your site but I keep getting the following error after each postback once the grid is created:
[GridException: Cannot find a column with UniqueName 'alert_id']
Telerik.Web.UI.GridTableView.GetColumn(String columnUniqueName) +102
Telerik.Web.UI.RadGrid.LoadClientState(Dictionary`2 clientState) +5156
Telerik.Web.UI.RadCompositeDataBoundControl.LoadPostData(String postDataKey, NameValueCollection postCollection) +109
Telerik.Web.UI.RadCompositeDataBoundControl.System.Web.UI.IPostBackDataHandler.LoadPostData(String postDataKey, NameValueCollection postCollection) +13
System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +690
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1743
I added the bound-columns to the mastertable before I set their properties.
The grid is created once, but each postback throws this error.
The error occures even before "Page_Load" happens.
My main goal is to add a button to the header which will open a custom context menu (so I can't use auto-generate-columns) and still have all the functionalities of group-by/sort/reorder etc. also, the grid's columns should be created dynamically since the datasource is set during run-time and I don't know what are its columns at design time - The grid is inside a RadTabStrip and each tab-click sets a different data source into the grid

I'm looking for a way to change the columns in the Image Manager. I use already the FileBrowser.ascx from the EditorDialogs folder. The problem is that there is only a ascx page and no code behind were I can change the default behaviour.
In the FileBrowser.ascx it looks like this (default):
The default columns are now Filename and Size, but I would also like to show the Title field from the Image library.
Is it possible to replace this with a custom class that has the RadFileExplorer as a base class? Or is it possible to change/add columns via JavaScript?

<telerik:RadFileExplorer ID="RadFileExplorer1" Height="450px" Width="400px" TreePaneWidth="150px" runat="Server" EnableOpenFile="false" AllowPaging="true" PageSize="100" />The default columns are now Filename and Size, but I would also like to show the Title field from the Image library.

Hi!
When using BinaryImage deployed on IIS with multiple worker processes (Web Garden) image is not always shown.
I assume it depends on that BinaryImage is using cache object and cache objects only lives in one worker process.
Any solution?

I'm a newbie with these Telerik controls. So, I am not sure where to begin.
Here is the requirements of the page I am trying to build
1. There is section on the page that prompts the user if they want to "attach" any files to this request. A request is a single row in the Request database.
2. So, I was plan on allowing the user to navigate and identify various files that they want to attach to this request. For each file that they identify, a row is created in table on the screen that contains the path and file name.
3. When the user submits the request (as in save the request to the database), then I would like to create a ZIP file for all those files listed in the table. Once the ZIP file is created, then I would like to save that ZIP into the database as a CLOB.
So, which Telerik controls should I use?
