RadWindow Popup closes automatically a second after opening

I am trying to display a page in a RadWindow however the RadWindow closes by its self after about a second of loading the new window. I was hoping someone could look at my code and see if they notice anything wrong. I am new to Telerik so sorry if something seems strange.

<telerik:RadScriptBlock runat="server" ID="RadScriptBlock1">

<script type="text/javascript">

function openWindow() {

var window = $find('<%= crWindow.ClientID %>');

alert("open");

window.show();

}

function onWindowClosed(sender, args) {

var ajaxManager = $find('<%= RadAjaxManager.GetCurrent(Page).ClientID %>');

ajaxManager.ajaxRequest('crWindow');

alert("close");

}

</script>

</telerik:RadScriptBlock>

<telerik:RadWindowManager runat="server" ID="crWindowManager">

<Windows>

<telerik:RadWindow runat="server" ID="crWindow" Title="test"

Behaviors="Close,Resize,Move,Maximize" OnClientClose="onWindowClosed" VisibleOnPageLoad="False"

VisibleStatusbar="False" Modal="true" Width="480px" Height="390px" KeepInScreenBounds="true" ShowContentDuringLoad="true"/>

</Windows>

</telerik:RadWindowManager>

<asp:Table ID="tableMasterMCA" runat="server">

<asp:TableRow>

<asp:TableCell>

<asp:LinkButton ID="lnkCR" runat="server">Test</asp:LinkButton>

</asp:TableCell>

</asp:TableRow>

</asp:Table>

I want the window to pop up when the link button is clicked so I also applied some c# code to the link button.

protected void Page_Load(object sender, EventArgs e)

{

lnkCR.Attributes.Add("onclick", "return openWindow()");

crWindow.NavigateUrl = "~/Pages/CRForm.aspx";

}

Apply radgrid filter on multiple grids

Hello,

I have a page with a RadListView multiple RadGrids binded on server-side with the same type of objects and same columns.

I would like to apply filters on all grids when changing a filter on one of them (client-side).

I tried handling the following client events on each grid :

- OnCommand, in order to save filters of the filtered grid in a global javascript variable

- OnGridCreated, in order to apply saved filters on each grid using the javascript variable

However, it doesn't work because my javascript variable is back to null value when hitting OnGridCreated event.

Is there a better way to do this (= sharing filters between multiple grids) ?

Thanks in advance.

Best regards,

Eva

Problems with Excel Import/Export

With regard to this previous thread: http://www.telerik.com/forums/rad-grid-import-from-excel

2 things.

First, I've examined the code and I'm a bit confused. I thought this technique only worked for XLS format, not the new XLSX.

Second, I have had an app up and running for some time now using that technique to import xls files without any problem.

Now, suddenly I cannot perform this operation locally in Visual Studio.2012 (It was working fine during the original development) It crashes: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

As far I know this is part of the package Microsoft Access Database Engine 2010. I have version 14 installed.

Suggestions?

RadComboBox Disabled After Postback

I have tried searching for this problem, so if this is a re-post please link to the original.

I have two RadComboBoxes inside a RadAjaxPanel (the latter is actually in a MasterPage), along with a regular ASP.NET Button control. When I click the button, I go through some simple validation to see if the user selected an item in each RadComboBox. If not, I make a <div> element visible with an error message, and exit the subroutine.

This works fine. However, after the button click and error message is displayed, the RadComboBox controls are disabled. They don't look grayed out, but clicking the drop down arrow does nothing, and mousing over the controls doesn't produce the normal "highlight" effect that shows when controls are active.

Regular ASP.NET DropDownLists do not produce this behavior. I'd really like to use the RadComboBox because I want the checkbox feature of it, but if I can't get this figured out in a couple hours I'll have to switch to ListBox controls.

Any idea what's wrong here?

Thank you,

Adam

Telerik Controls not loading correctly

I am having serious issues with Telerik controls not loading on the page without multiple refreshes.

Here is an example of how the HTML editor looks when it fails to load. This happens to pretty much all controls.

Using version: Telerik_UI_for_ASP.NET_AJAX_2015_3_930_Dev

No errors are being thrown on the server.

Reordering columns client side & Saving order in DB

Hello,

I was looking for a way to allow my users to customize their interface, and to choose the columns order of some grids.
I choose a client side reordering as I don't want the data to be reloaded (too long) and the ongoing modification lost (GridEditMode.Batch).

In order to save the preference of the user, I susbcribed to the "onColumnSwapped" event. Then my javascript function calls "ajaxManager.ajaxRequest" (which save the new columns order into my database)

First issue: in my "RadAjaxManager1_AjaxRequest" (server side), if I look the OrderIndex of the columns of my grid, they have their original values. Is this normal ?

I could decide to save the profil with a custom button "Save Column Order" (I tried and the OrderIndex are the correct / changed ones) but I want to avoid adding another button to my interface.

As I already have the column order stored server side, I decided to simply send the two argument from the javascript to my server function:

var sourceIndex = eventArgs.get_gridSourceColumn().get_element().cellIndex;

var destinationIndex = eventArgs.get_gridTargetColumn().get_element().cellIndex;

Then I make the change myself server side and save it to the database.

It works well with GridClientSettings.GridColumnsReorderMethod.Swap.

However it doesn't work with GridClientSettings.GridColumnsReorderMethod.Reorder. The javascript event is called multiple times (swapping multiple time) but the ajax request is called only 1 time ! (the last time).

Example: If I move the 4th columns to position 1.
The javascript event is called 3 times with the following parameters (source, destination):
4,3
3,2
2,1

And my AjaxRequest is called only 1 time with the following parameters (source, destination):
2,1

Any suggestions ?

Thank you
