Hello,

I have my aspx page with radgrid, but I do NOT see the property like OnNeedDataSource="RadGrid1_NeedDataSource"

But I am still  be able to get to the event in code behind file. Is it possible with radgrid and am not sure.

What would be the possible cases here?

It would be great if you could change the Header Text and save as part of the layout.

I have an application that is used by different customers. The base tables are the same but the customers want to name the columns differently.

I really want this something they can change and save as a user or system setting.

I am trying to come up with a good way to have a standard page that allows this functionality that I can use throughout my site.

Question 1. Can this be done in the layout saving/presistance?

Question 2. Is there a good way to provide a means to click on a header and allow modification of the header text.

Tried putting something in the context menu without success?

Any help would be much appreciated.

Thanks!!!

In code behind

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{

if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
{
GridEditableItem item = e.Item as GridEditableItem;

if (e.Item.OwnerTableView.Name == "Students")
{
GridEditFormItem editFormItem = (GridEditFormItem)e.Item;
ListBox listBox1= editFormItem.FindControl("ListBox1") as ListBox;

}

}

}

Am getting null value when find the listbox.

Kindly help me to sort out this issue.

We are using Rad Editor, to attach the images (ImageManager/Document Manager) is not loading any images in the image list (IE Version 11).

Allowed file types are :

Editor.DocumentManager.SearchPatterns = "*.jpg,*.gif,*.png,*.xlsx"

Can anyone please help to resolve it !!!

I have a RadGrid on an ASP.Net page with VB.net as the code-behind.

The columns are not auto-generated.  Some columns are hidden when the RadGrid is first loaded by setting the Display property to false.  This is the Summary View.  I have a RadioButtonList to allow the user to choose between Summary View and Detail View.  When the user selects Detail View, the columns that were hidden have their Display property set to True and then can see the hidden columns and their data.  This is done in the PreRender event procedure for the RadGrid.

I need to add a new column that has a link, image button, push button, or something that when clicked on will open a new window using radopen in a javascript function with a different ASP.Net page that has some of values from the row that was clicked on.

Also I am using the RadTabStrip so the user can see the windows that were opened.

I have looked at several threads in this forum regarding people trying to do the same thing or something similar and have tried the sample code that someone from Telerik provided or sample code other people posted.  Nothing worked.  I have tried a GridButtonColumn and a GridTemplateColumn.  

For now, I have set up a simple Javascript function that calls the alert function for testing.  The javascript function was put in a separate javascript file called scripts.js which is loaded by the ASP.Net page with RadGrid by using the following line of code: <script src="/Scripts/scripts.js" type="text/javascript"></script> .

The closest I was able to get something to work just showed the alert window pop up but was not able to access the data from the row that was clicked on.

One of the things I have tried caused an error to occur when selecting Detail View.

Please help.  Thanks!

Sincerely,

Hi,

We are upgrading our application framework from 3.5 to 4.5? Facing following javascript errors in webresource.axd in some pages
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled

Is telerik 2008 version supports any .Net framwork higher than 2.0? if yes, any recomendations?

Please help.

Venu.

Dear users,

for a winform application i use a database like in the attached picture suggest-db.jpg with success, inspired and modified for my app starting from http://www.telerik.com/blogs/data-binding-with-radscheduler-for-winforms.

Here in a 2nd table AppointmentsResources the AppointmentID and the ResourceID is stored.

Is it possible to use the same db structure for ASP.NET AJAX scheduler because there a different datasources is used for the ResourceTypes Collection.

For me it seems not, because i can't update my AppointmentsResources table, just the dataset for the scheduler itself.

Any suggestion how to bring my resource value into AppointmentsResources.

Or must i have a seperate field for every resourcetype im my Appointment Table.

Kind regards

Martin
