[Solved] Fire javascript alert before changing page

Hi all,

I would like to fire a javascript confirm popup when the user wants to change page (by setting a page number or by using previous / next page buttons).

Here is a quick description of the grid :

A user can update some input fields in a grid and a button below the grid lets the user save the values. I would like to prevent him from losing its updated data when he changes page by displaying a javascript confirm popup.

The confirm popup will ask if he really wants to change page and if it is the case, we lauch the postback and we change page. If not, the page change event is canceled and the user can save its values.

Thanks

Finding Label in hierarchical RadGrid

I have a hierarchical Telerik RadGrid that sometimes contains child entries that are empty. For these, I want to overwrite the default text "No child records to display" with something user locale specific.

So I can do this:

<telerik:RadGrid ID ="SettingsGrid" ... /><br>

<mastertableview ... /><br>

<DetailTables><br>

<telerik:GridTableView ... /><br>

<asp:Label ID="NoRecordLabel" runat="server" Text="whatever"/></div></NoRecordsTemplate>

Which causes the text "whatever" to appear when it should.

But I obviously want to do this dynamically, but I have failed in both of two ways:

1) By referencing my .resx file in the .ascx file. I import it's namespace and reference a certain resource as such:

Text="<%$ Resx:SiteTextResources.Globals_Close %>"

(This works in other files in the same solution)

But this only produces empty text.

2) I haven't been successful at retrieving the Label programatically from the code behind. I looked at this: http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-access-controls-in-norecordstemplate.aspx but didn't get that approach to work, as I just can't seem to find the Label. I get an OutOfBoundsException, which I guess means the GetItems() method returns null.

Any ideas? Would appreciate it a lot!

Radgrid- Custom selection of ROws/ Disabling selection of rows /client side implementation

Hello,
We are trying Radgrid for our project requirements we have a specific requirement to disable selection of certain rows based on "True/False" values returned from a column in database. We want to have functionality to disable those rows for which a specific column is returning "False" and we want to enable this feature with hierarchy .
We tried going for Template field, GridSelectColumn and tried using "Selectable.Mode to None" but we were not able to achieve the results and we need a client side solution /using some inbuilt property for our problem as our grid would hold around 1 million records so handling such scenario on server side/codebehind is the scenario we want to avoid.
Kindly reply to suggest some ways /features we can achieve our requirement. We have enquired for professional license so we will be getting professional license this week , so please help us on achieving this requirement.

Thanks& Regards,
-Dinesh Kotwani

SPRadEditor control localization problem

I have a problem when trying to localize SPRadEditor control. I am changing language but it stays English anyway.
Telerik.Web.UI: Version=2013.2.717.35
RadEditorSharePoint: Version=6.7.1.0
My actions:
Add telerik control to my cutom web part, change Language property to "de-DE":

<telerik:SPRadEditor ID="ContentInputTextBox" Language="de-DE" OnClientLoad="RadEditorLoad" CssClass="articleformcontrolfull" runat="server"><CssFiles><telerik:EditorCssFile Value="~/EditorContentArea.css" /></CssFiles></telerik:SPRadEditor>

Add language property to ConfigFile.xml and ListConfigFile.xml in C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\wpresources\RadEditorSharePoint\6.7.1.0__1f131a624888eeed\Resources folder:

<property name="Language">de-DE</property>

Deploy. After all those actions language for all elements stays English and don't changes.
What I am missing here? Or what I am doing wrongly? Thank you for your help.

[Solved] Selecting invalid files.

Hi

I want my web users to select only .jpg/.png files to be uploaded and set the AllowedFileExtensions property and found that it works rarely because of some browser limitations. So If the user selects an invalid file, I want to display an alert and bring the control back to its original state instead of displaying the selected file as an invalid one.( The one shown as Red). Please help.

Thanks
Dona.

RequiredValidator error when bind selected value

In edit mode of the grid, there is a dropdownlist for user to select.

For new record, it will select default message "Please select"
For existing record, it will databind the value from db to become selected value

I had added the requiredvalidator to make sure user had selected dropdownlist.
it works when user create a new record, it will display error message if user not select.

but it had error when user edit the record, even though the dropdownlist had selected value.
it still display error message
