this should be an easy one, but I haven't been able to find it in the documentation. I have a simple grid that is read-only where the user can click on a hyperlink column to view the record details. Since the user cannot add new records I want to not show the default 'Add new record' text and button that displays at the top of the grid.

thanks

Refresh items without rebinding

I have two nested RadComboBox controls. Both "SelectedValue" properties are bound to a LinqDataSource, and they both get items from different ObjectDataSources.

When I select an item in RadComboBox1 I want to update RadComboBox2's items but I'm getting the following error "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control." as RadComboBox2 is also rebinding the SelectedValue property. To solve this, I unbind RadComboBox2.SelectedValue and set the field's value later, but I'm looking for a nicer option.

Is there anyway to refresh RadComboBox2 items withouth the whole rebind, so as to prevent the exception from raising?
Thanks a lot!

Allow user to resize RadTextBox

I believe I saw a way to do this before, but I can't find it now. Is there a way to allow the user to expand the dimensions of a RadTextBox? Thanks.

How to angle text in the xaxis textblock?

Hi,

I have a radchart with the names of states being set for the xaxis, like so.

hoursRadChart.PlotArea.XAxis[i].TextBlock.Text = data.State_Name;

But the text is bumping into itself and unreadable. How do I rotate the text 90 degrees?

Thanks,

Ryan

GridDropDownColumn not working with RadAjaxManager

Hi,

I am building a RadGrid, which has a GridDropDownColumn in it. I have enabled ajax on the RadGrid using the RadAjaxManager, but after I do this, the ComboBox in the GridDropDownColumn no longer drops-down, it just gets stuck and doesn't do anything when you click it.

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<asp:EntityDataSource ID="dsTypes" runat="server"

ConnectionString="name=Entities" DefaultContainerName="Entities"

EnableFlattening="False" EntitySetName="Types">

</asp:EntityDataSource>

<asp:EntityDataSource ID="dsCustomerData" runat="server"

ConnectionString="name=Entities" DefaultContainerName="Entities"

EnableFlattening="False" EnableUpdate="True" EnableInsert="true"

EntitySetName="CustomerData" AutoGenerateWhereClause="True" Include="Type">

</asp:EntityDataSource>

<telerik:RadGrid ID="RadGrid1" runat="server"

GridLines="None" DataSourceID="dsCustomerData"

AutoGenerateColumns="False" AutoGenerateEditColumn="True" AutoGenerateDeleteColumn="True"

>

<MasterTableView DataSourceID="dsCustomerData" DataKeyNames="CustomerDataID">

<RowIndicatorColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<Columns>

<telerik:GridDropDownColumn DataField="TypeID"

DataSourceID="dsTypes"

HeaderText="Type" ListTextField="TypeName"

ListValueField="TypeID" UniqueName="TypeID">

</telerik:GridDropDownColumn>

<telerik:GridBoundColumn DataField="Make" HeaderText="Make" UniqueName="column">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Model" HeaderText="Age"

UniqueName="column1">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Age" HeaderText="Age" UniqueName="column2">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

If I remove the RadAjaxManager, the ComboBox works as normal.

Any ideas?

Thanks,

Craig

[Solved] Performance Questions

I'm struggling with a performance issue I can't seem to resolve. I cannot reconcile the difference in performance on my local application compared to the telerik demos online.

I have gone through most of the articles here on performance. I'm using CDN and just installed the latest version of ASP.NET AJAX components. I'm still using them in trial because I'm not quite getting the experience I need.

I have a page with 1 rad tab (with three tabs) one tab has a scheduler the other two tabs have radgrids.

On my local network running in VS or on my local server the performance seems good. When I access the server from a PC off my network it's quite slow. The only difference I can really think of is the speed of my network to the web. The problem is I've conducted all sorts of tests and even on a very slow connection the telerik demos run faster.

Is it because it's a trial version? Am I missing something in the config? Have I combined too many Rad components on one page? I've verified all the scripts and styles are coming from the CDN settings and the page itself is only about 100k when complete. Are the scripts just taking that long to run on the client computer? The database certainly isn't a bottleneck. I've watched with profiler and the queries are all wrapped up long before the page re-renders completely. Could it be the code running on the client taking a while to get going? Basically if you right click an item on the scheduler and "edit" it takes nearly 18 seconds to bring up the edit dialogue. It takes nearly the same amount to save or cancel it after that.

Thanks for any tips or insights!
