Example of [Telerik.Web.ClientControlMethod(true)] ?

Hi all,

It looks like this server-side method attribute allows the server method to be controlled somehow through client scripting.

Is this correct? If so can a short example be provided please?

I tried just calling the function in script and got an 'Object was expected' null reference error.

Thanks :)

EnableLinqExpressions throwing exception

Hello,

Im having an issue with the RadGrid and allowing Column Filtering. Basicly what has happened is that we had a grid. we had filtering on it and the filtering worked for awhile. we updated our controls to .1314, afterwards filtering started throwing an exception "no property or field 'username' exist in object". from my understanding this was an issue nearly a year ago and hotfix was applied.

to make things worse is that through searching the forums i found out setting the EnableLinqExpressions = false will allow the filtering to happen without throwing an exception, but when i set that property to false, the paging on the grid no longer works. the telerik pager, defaults to page 1, but when you click page 3, the pager is saying page 3 but the grid itself is still displaying records from page 1.

for awhile i believed it to be an ajax problem and i disabled all the ajax on the page and the problem still persist.

so, in a nutshell, if EnableLinqExpression is not set to False, we cannot use the Filtering provided in the control, if we do set EnableLineExpression to False, the pager does not work appropriately.

any help at all would be appreciated.

[Solved] ListBoxItem checkbox not checked in edit mode

I have a RadListBox in an editable FormTemmplate inside a RadGrid. The ListBoxItems have checkboxes, and their data values are populated with a SQL DataSourceId. When I select a grid row to edit, and the form populates, the ListBoxItem that matches to the data record is highlighted (selected), but its checkbox is not checked as it should be. I've looked for a property to control this without luck. How can I bind the ListBox such that it will check 'on' the selected ListBoxItem(s)?

This is the html:

<telerik:RadGrid ID="rgTodos" runat="server" EnableAJAX="True" AllowAutomaticUpdates="False" OnItemCommand="rgTodos_ItemCommand">

<MasterTableView CommandItemDisplay="Bottom">

<EditFormSettings EditFormType="Template">

<FormTemplate>

<table style="width: 80%" align="center">

<telerik:RadListBox ID="listWho" runat="server" DataSourceID="dsTodoWho"

DataTextField="wholist" DataValueField="who" Height="100px" Width="169px"

Skin="Vista" CheckBoxes="true" SelectedValue='<%# Bind("who") %>'

SelectionMode="Multiple">

</telerik:RadListBox>

Thanks, Dan

[Solved] checkbox in Parent and child grid

Hi,
I am working on RadGrid. I have problem about MasterTableView and DetailTables.

In my scenario, My Parent grid have a checkbox and Child grid also have checkbox. When I check Master parent grid row then child grid checkbox row checked all the row automatically. e.g.

1001 computer 1000 USD (checkbox)
1 mouse 500 USD (checkbox)
2 Key broad 500 USD (checkbox)

In above example 1001 row is my parent grid row and remaining are child grid rows. When i checked the parent grid checkbox then child grid checkbox automatically checked. I hope you understand my logic.

Clicking a button inside a ajaxified usercontrol using javascript

Hi,

I am having a radgrid assosiated with a radajaxmanager and radajaxloadingpanel. I am using usercontrol insert and edit forms. I am having a button inside insert form (usercontrol). On click of that button i want to confirm with the user. So i wrote the script to call a radconfirm onclientclick of that button and if [OK] button is clicked in the confirm box, i am programatically calling the button click from javascript code using buttonObj.click();

My code works well in following cases,
1. if i use image button in place of asp:button (or)
2. if i remove the radajaxmanager and ajaxpanel from the the parent page.

But not with the normal asp:button. Can you please help me in sorting out the problem.

My script to call radconfirm,

<script type="text/javascript">

var buttonObj;

var confirmValue = false;

function UpdateConfirm(btn) {

if (!confirmValue) {

buttonObj= btn;

var confirmString = "Do you wish to update?.";

radconfirm(confirmString, UpdateConfirmCallBackFn, 300, 120, "", "Confirm Update");

return false;

}

} 
    function

 

 UpdateConfirmCallBackFn(arg) {


        if (arg) {
 
            confirmValue=


true;
 
            buttonObj.click();
 

        }
 
   }

My button inside the usercontrol insert form,

<asp:Button ID="btnUpdate" runat="server" Text="Update"

ValidationGroup="grp" OnClick="btn_Click" OnClientClick="return UpdateConfirm(this);" />

My RadAjaxManager Code in the parent grid page,

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default">

Loading...

</telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="grid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="grid1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

[Solved] ResourceType not allowing multiple values when using provider

I'm testing the RadScheduler in an MVC app using a custom provider. When setting resource types, I use the following code:

public override IEnumerable<ResourceType> GetResourceTypes(RadScheduler owner) {

List<ResourceType> resourceTypes = new List<ResourceType>();

resourceTypes.Add(new ResourceType("Staff", false));

resourceTypes.Add(new ResourceType("Client", true));

return resourceTypes;

}

However, when adding/editing appointments in the Scheduler, both Client and Staff resource lists show up as a single-choice dropdown, rather than the multi-choice checkboxes expected for the Client type.

If I specify the ResourceTypes at design-time using the Resource Type Editor, the Client resources are displayed correctly with checkboxes. This is a tolerable solution, but it defeats the purpose of specifying ResourceTypes from the provider, and seems to contradict the information in the help file saying that the Scheduler gets its information from the data provider.

I've also looked at the article telling how to create a provider that supports multiple resource values, but that article is out of date as the provider property 'SupportsMultipleResourceValues' is now listed as obsolete.

Is the Scheduler supposed to use ResourceTypes as specified by the provider, or is using the Resource Type Editor the only way to allow for multiple resource selection?

Thanks
