The online demo here do not include the file: "Explorer.aspx" used by RadWindow.

I cannot see any property like "DialogMode=FileSelector" on the control itself.

Have anyone tried to setup the "File Selector Dialog" example, and made it work?

A generic error occurred in GDI+

Hello,
We are using the Telerik build 2010.2.929.40 and occasionally on our app served from a new Server 2008 we receive this error when viewing a RadChart, "A generic error occurred in GDI+." We can recycle our app pool on the server and the charts go back to normal with no errors. Then after a few hours or days the error comes right back and occurs for anyone trying to view the RadChart. Were there any known issues with memory leaks or image file locking issues in this build? Has anyone else experienced a similar issue?
Thanks.

GridTemplateColumn - unwanted border

I've seen a few similar posts, but not this exact issue:

I'm getting some un-wanted vertical borders when using a GridTemplateColumn. I'm not sure if I just have some setting wrong or maybe just missing an a type.

I have a screen shot, but I'm unsure of how to insert that into the thread.

Here is my RadGrid code:

<telerik:RadGrid ID="RadGrid1" Skin="Forest" Width="97%" AllowSorting="True" EnableAJAX="True"

AllowPaging="True" PageSize="25" runat="server" OnSortCommand="RadGrid1_SortCommand" OnPageIndexChanged="RadGrid1_PageIndexChanged"

AllowFilteringByColumn="false" GridLines="None" >

<telerik:GridTemplateColumn UniqueName="TemplateColumn1">

<tr><td align="center"><b>Test Template</b></td></tr>

</

table>

</HeaderTemplate>

</table>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

RadGrid - Inserting Records with confirmation dialog on duplicates

Hello,

I am using a RadGrid as part of a custom control (DNN module, actually) for contact management. I have a simple RadGrid set up with an external insert/edit form, and aside from the issue with allowing duplicate inserts, it's working perfectly.

When inserting new records, or updating existing records, we want to detect duplicate records (based only on fistname and lastname comparisons) and prompt/warn the user to ensure they are aware of the duplicate.

In the case of no duplicates, the insert/update should just happen.
In the case of duplicates, the user should be asked if they want to insert anyway, or cancel.

Does RadGrid have any kind of built in support for this kind of workflow? Or am I going to have to replace the current submit button with my own method that makes an AJAX call to search for duplicates, and then react accordingly? I am trying to keep the code as simple as possible for long-term maintenance purposes.

Thanks,
Dave

AllowCustomPaging and export command

Hi,

I'm using radGrid with custom paging. I also use NeedDataSource event to get data.

I stuck when I click Export command in item Command row (I only have export command). I dont know how to distinguish that export command is clicked inside NeedDataSource method (because its executing before Export event of grid).

I have tried this:

if (e.RebindReason == GridRebindReason.ExplicitRebind)

{

rgActions.AllowPaging = false;

rgActions.AllowCustomPaging = false;

}

else

{

rgActions.AllowPaging = true;

rgActions.AllowCustomPaging = true;

}

but its not ok because explicit rebinding is also done when any othe button is clicked on page that rebind grid.

RadListBox - Set width dynamically depending on Text of Item

Hello,

By default every item text gets wrapped if its longer than width of RadListBox.
How to set width of RadListBox dynamically based on text of item. Basically I want to expand width of RadListBox, without wrapping text of item.
In below example, 3rd item gets wrapped automatically. I want to expand RadListBox in a way that it can fully accommodate 3rd item without wrapping or scroll bar.

<telerik:RadListBox
        runat="server" ID="RadListBoxSource"
        Height="200px">
        <Items>
            <telerik:RadListBoxItem Text="China" Value="1"/>
            <telerik:RadListBoxItem Text="Egypt" Value="1"/>
            <telerik:RadListBoxItem Text="England England England England England England England England England" Value="1"/>
            <telerik:RadListBoxItem Text="France" Value="1"/>
        </Items>
    </telerik:RadListBox>

Appreciate any help.

Thanks

Multiple Resource Values for Recurrence

HI,

I tried Implementing A Provider That Supports Multi-valued Resources. It works fine for appointment without recurrence. When I switch from day view to week view it will show following message if there is an appointment with recurrence.

Error: Sys.WebForms.PageRequestManagerServerErrorException: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

By the way, I tried to create a appointment with recurrence on your demo site using following link. It also throws exception:

http://demos.telerik.com/aspnet-ajax/scheduler/examples/multipleresourcevalues/defaultcs.aspx

Please let me know how to fix this
