Radgrid PreRender - Selected Items Issue

I am using pre_render to set select items in a rad grid in a user control. The method below is based on some Telerik posts. The checkboxes are populated when the user control opens for me locally and on the production server using IE8. But for other users (also using IE8), the check boxes only populate on postback. I have tested using compatibility mode on and off and do not see a change in behavior.

Any ideas or suggestions? It is challenging that the code is the same but the behavior is varying for some users.

Protected

Sub RadGrd_PreRender(sender As Object, e As System.EventArgs) Handles RadGrd.PreRender

If Not (Session("SelectedItems_" + ClientID) Is Nothing) Then

strSelectedItems = Session("SelectedItems_" + ClientID)

For Each item As GridItem In RadGrd.MasterTableView.Items

If TypeOf item Is GridDataItem Then

Dim dataItem As GridDataItem = CType(item, GridDataItem)

Dim chkBox As CheckBox = CType(dataItem("CheckBoxTemplateColumn").FindControl("CheckBox1"), CheckBox)

If strSelectedItems.Contains("," + dataItem.OwnerTableView.DataKeyValues(dataItem.ItemIndex)("ID").ToString() + ",") Then

chkBox.Checked =

True
Else

chkBox.Checked = False

End If

End Sub

Duplicate Folder List Issue

See the attached pic to have a visual view of the issue: radfileexplorerexample.png

Coding Front is simply:

<telerik:RadFileExplorer runat="server" ID="RadFileExplorer2" Width="500px" Height="300px"

EnableOpenFile="true" EnableCreateNewFolder="true">

</telerik:RadFileExplorer>

Code behind is:

RadFileExplorer2.Configuration.ViewPaths = new string[] { "~/Files", "~/Files" };

RadFileExplorer2.Configuration.UploadPaths = new string[] { "~/Files", "~/Files" };

RadFileExplorer2.Configuration.DeletePaths = new string[] { "~/Files", "~/Files" };

This is just an isolation of code to see if that issue was there. I tested it by plugin with a data model, that was where we noticed that issue.

Can anyone help please? Thanks!

Grouping error on in code created column

Hello,

I create a gridboundcolumn from codebehind and try to group it.
It throws an exception:

Unhandled exception at line 885, column 13 in http://server1/ScriptResource.axd?d=1A_JfTzkVI_BPK0wyueglza3uf3p5EQOp4lCh3bkZFj2kwIlPrGfNBqAYyJG42yrzLhNfZTtBWoYuqokkf-vNOdy8LQfqHEEJse-2Zpg5nGn_znQ0ma5rdc2XuV8eHZvGcbaSsZ0Wu1n7TPfMrcwAYGxAJyYoPMx7lFZ_2kSkbfeRFZ1GXIexwskAgJ3NeM67J1V_H9-C5a9cYJV09SQKA2&t=6119e399

0x800a139e - Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Expression cannot be null or empty

Whats the correct way to create a column from codebehind?

Marcel de Groot

-----------

I create the column like this:

GridBoundColumn col = new GridBoundColumn();

col.UniqueName = field.UniqueName;

col.HeaderText = field.Caption;

col.DataField = field.UniqueName;

// col.GroupByExpression =field.UniqueName + " Group by "+ field.UniqueName;

col.SortExpression = field.UniqueName;

col.HeaderButtonType = GridHeaderButtonType.TextButton;

RadGrid1.Columns.Add(col);

when i define the columns in the markup like this it works:

<MasterTableView Width="100%">

<GroupByExpressions>

</GroupByExpressions>

<Columns>

<telerik:GridBoundColumn SortExpression="Key" HeaderText="Key" HeaderButtonType="TextButton"

DataField="Key" >

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

Add update panel label to RadEditor status bar

I have code that shows a Modified label when there have been changes to the editor and it works great, except when the editor is in full-screen mode and then the label cannot be seen.

I'd like to add the update panel (with the modified label) to the status bar - the area (div class="reModule" span) that contains the text "Words: 0 Characters: 0".

I've tried moving the update panel with the following code, but it doesn't work even though it finds the controls. In IE, the update panel no longer is visible and in Chrome, it apparently has no effect.

var reModuleDivs = document.getElementsByClassName("reModule");
var reModuleDiv = reModuleDivs[0];
var notesEditorUpdatePanel = document.getElementById("<%= notesEditorUpdatePanel.ClientID %>");
reModuleDiv.appendChild(notesEditorUpdatePanel);

Is there any simpler method to go about adding an update panel / label to the bar that contains the status text?
