Hi,

I have a radgrid that is bound on the client-side using json response.  I run into a situation where my response can return no data (i.e.

{"d":[]} )  in this case I'd like to write something like 'No data records' to the first row/cell.  
How can I do this using the client-side API?






Thx

I'm using a RadAjaxManagerProxy along with a ScriptManagerProxy in a page with four RadGrids, the RadScriptManager and RadAjaxManager are in the master page, and our testers keep generating errors like this every few hours or so:

Obviously it's hard to capture any specific event which triggers this, I suspect I'm leaking memory somewhere over time - are there any use patterns which might lead to this?

One thing I notice when looking at the code is I have some script references in the head instead of being sent through the script manager, would the Ajax manager keep re-adding them to the page on every request and eventually lead to the out of memory issue?

I have a grid with AllowFilteringByColumn="true", filtering on all columns is enabled and AutoPostBackOnFilter="false" for all columns. What I would like to do is only apply the filter when a user clicks a button either in a custom CommandTemplate or outside the grid (either one will work fine). There are two problems that are stopping me:

1. How do I fire the filtering from code-behind? I know I can do it client-side but...
2. Any column that has the filter icon will fire the filtering on selecting a value.

If I can do #1, then I can disable the grid's filtering client-side and fire the filtering using the button's click event. If I cannot fire the filtering in code-behind, then is there a way of disabling the firing of a postback on choosing one of the filter choices?

I have a grid akin to the following which has as its DataSourceID a LinqDataSource:


All columns have AutoPostBackOnFilter="false" and have a SortExpression. Whenever I click the button in the CommandItemTemplate I get the following error:

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

For those that answer with "use Advanced Binding", how do I replicate all the functionality of the LinqDataSource in code-behind?

Hi,

Any help on this matter would be greatly appreciated, I have been stuck on it for a good while now.

I have a radtoolbar, I have two events handled:

OnClientButtonClicked="RadToolBar_ClientButtonClicked"
OnButtonClick="RadToolBar_ButtonClick" 

Depending on the outcome of the RadToolBar_ClientButtonClicked method (javascript) I would like to/not to handle the OnButtonClick event using the RadToolBar_ButtonClick (c#) - that is, if the client-side method returns false I would like the server-side method to just not execute (I don't even want an alternative method to run, just want it to do nothing).

I have tried the following..

OnClientButtonClicked="return RadToolBar_ClientButtonClicked()"
and
OnClientButtonClicked="return RadToolBar_ClientButtonClicked();"

...but on doing this the page simply does not load (remains blank white).

Thanks a LOT!!!

Hello
Im trying to filter the radgrid with filtertemplate. the code look's like this

and when I change the item of combox nothig happens the items are not filterd, what can be wrong?

Hi,
Is any way to merge two RadWindows into one RadWindow?
On the left: 1. RadWindow and on the right: 2. RadWindow.

Best reagards.

I see your demo of the new AsyncUpload control claims:

RadAsyncUpload provides client-side event called OnClientValidationFailed. It is fired when the selected file has invalid extension or its size is higher than the MaxFileSize property.

The demo, however, is validating file size on the server. Is there still a problem with client-side filesize validation, or is the demo just not configured to use it?

Thanks,

Craig

I am using a SharePoint 2007 PublishingPage to display a RadHtmlField as follows:

<

 

telerik:RadHtmlField ID="RadHtmlField1" FieldName="Content" runat="server" ToolsFile="/_wpresources/RadEditorSharePoint/5.8.6.0__1f131a624888eeed/Resources/QAAInternetToolsFile.xml" ConfigFile="/_wpresources/RadEditorSharePoint/5.8.6.0__1f131a624888eeed/Resources/QAAInternetConfigFile.xml"></telerik:RadHtmlField>

 

I wish to use Image Manager to insert images from both the SiteCollection and the current website. Looking at the documentation my ConfigFile.xml should look like this:

<configuration>
 <property name="ToolbarMode">Default</property>
 <property name="ToolsWidth">680px</property>
  <property name="ImagesPaths">
           <item>PublishingImages</item>
           <item>/SiteCollectionImages</item>
  </property>
</configuration>

When I click ImageManager it shows both folder locations defaulting to the current website image folder which is good. When I click on the second folder it displays the site collections images which is also fine. But, if I then click on the first folder again it will not change - it stays fixed on the site collection folder.

This looks like a bug. Is there a way around it?

When there is a single column relating two tables defining GridRelationFields is straight forward:

However, how do you define a GridRelationFields when the keys are compound, such as:

This is not uncommon.

Must I create an autoincremented column in the parent table and then rely only upon that in the child table?
