Hi Telerik

I am using RadConfirm dialog in my asp.net web form to get the user confirmations. Since the user can click OK or cancel and there is a third possibility that he can click the X button to close. Therefore how to differentiate between these user interactions?

Multiple file selection not working in IE9 browser.

Hello

I have an asyncupload control in user home page to upload multiple .docx files. The page is working fine in chrome browser and now for testing purpose when I checked the same page in IE9, the user is unable to select multiple files. On searching I read about upload modules and installed flash plugin and still the issue is there in IE9. What can be the reason behind?

Note I am not using Manual upload and havent set any DisablePlugins.

Thanks for replying,
Freddy.

Rebind: Cannot perform this operation when DataSource is not assigned

Basically I can't refresh my RadGrid. I have filters above the RadGrid that I apply when the user hits the RadGrid's Refresh button. With or without Ajax, whether or not I intercept the ItemCommand event, whenever it finally calls Rebind it fails with this error: Cannot perform this operation when DataSource is not assigned. It is true the DataSource is null before the call. What's interesting is the NeedDataSource event fires off without a hitch, and when the exception gets back to me the DataSource is properly assigned. I haven't messed with ViewState, so I believe that should still be enabled (or rather inherited seems to be the default nowadays). What am I doing wrong?

Let me know if you'd like to see any of my code, but after staring at it for hours I'm convinced that it's something else I don't know.

Thanks.

Fire Insert/Update/Delete events in button click outside grid

Hi,

Currently i have the items in the grid getting inserted/deleted/updated in the "oninsertcommand/ondeletecommand/onupdatecommand" events.

However, I want to do these grid changes only when the submit button is clicked.

Currently in the grid I have the below UI:

OnInsertCommand="radgrid1_InsertCommand" OnUpdateCommand="radgrid1_UpdateCommand" OnDeleteCommand="radgrid1_DeleteCommand"

How to achieve Insert/Update/delete in the submit button click?

Open bigger RadWindow inside a parent RadWindow

Hello all,

I need to open a RadWindow inside another RadWindow, but my requirement is to open child window bigger than the parent window.

The below article fulfills my requirement, but It is in Q3 version and I am using Q1 version.
http://demos.telerik.com/aspnet-ajax/window/examples/autosize/defaultcs.aspx

So please suggest, if there is any workaround in Q1 version.

Thanks

[Solved] Export to Excel Using an Iframe

Hi All

My Layout is as follows:

Master Page (ScriptManager)
Content Page
  DropDownList
RadDock
    asp:Panel
       UserControl (ascx)
           iFrame (ifmExcel)
           RadGrid

We have ajax settings so that the dropdownlist refreshes the user controls. We would like to maintain this.

The way I got the export to work with a REPEATER was using :

System.IO.

StringWriter stringWrite = new System.IO.StringWriter();

System.Web.UI.

HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);

myRepeater.RenderControl(htmlWrite);

Session[

"ExportBody"] = stringWrite.ToString();

ifmExcel.Attributes.Add(

"src", "GenerateDownload.aspx");

The GenerateDownload would process the body and response.write as normal.

Is there something similiar we can do for the radgrid to have it loaded in an iframe or what's the best way to go about exporting the data?

I saw the render control for the rad grid, but if we can get it to use the export settings for the binary format in this setup that would be ideal.

Thanks in advanced.

FormView Will Not Go Into Edit Mode w/RadAjaxManager

I have 2 RadTreeViews and a FormView on a form.

When something is clicked from the first TreeView, it populates the second one. When something is clicked from the second RadTreeView, it populates the FormView. All of this works perfectly up to here.

When I click the "Edit" link button of the FormView at this point, nothing happens. Even when i attempt to do it manually from code - nothing happens.

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="treeSellers">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="lblBuyers" UpdatePanelCssClass="" />

<telerik:AjaxUpdatedControl ControlID="treeBuyers" UpdatePanelCssClass="" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="treeBuyers">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="formBuyerDetails" UpdatePanelCssClass="" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Simple Edit Button on the FormView's ItemTemplate:

<asp:LinkButton ID="link_edit" runat="server" CommandName="Edit">Edit</asp:LinkButton>

Protected Sub formBuyerDetails_ItemCommand(sender As Object, e As FormViewCommandEventArgs) Handles formBuyerDetails.ItemCommand

If (e.CommandName = "Edit") Then

formBuyerDetails.ChangeMode(FormViewMode.Edit) 'Doesnt Work

ElseIf (e.CommandName = "Cancel") Then

formBuyerDetails.ChangeMode(FormViewMode.ReadOnly) 'This probably doesnt either, but I cant even get here

ElseIf (e.CommandName = "UpdateBuyer") Then

'UPDATE function here

End If

End Sub
