Hi,

I am trying to delete a row with the same code in the Telerik code sample, but my DataKeyValues is always empty.

Here is my code:



My DeleteCommand event currently do nothing, because it fail on the single line with a IndexOutOfBound.

Am I missing something? Thanks.

i have a radgrid within a radajaxpanel within an ajax control toolkit tab which is populated based upon the selection of a row from another tab. when i click to the first described grid, selection fails even though selection is enabled. when i click a row's edit button and then cancel, selection works.

the insert row button has been redefined to open a radwindow to select a row to populate the parent grid:

this alteration shouldn't matter but i have included it in the event that it does.

why does the grid not select when first loaded? i have seen at 2 other threads on this subject without any obvious resolution.

I am using client side binding to the grid. When I first load the page, I get a single call to my GetData() web service method as expected. If I click a number in the pager, however, I get the first call and data returned as expected, but then the grid calls the data function again and reloads the data with the parameters set as though the first page is being requested, which means the grid can never show pages other than the first page.

Your documentation has guidance on how to keep this from happening, but I have not been able to get any of the techniques to work:

http://www.telerik.com/help/aspnet-ajax/grid-custom-paging.html

I also tried this technique:

http://demos.telerik.com/aspnet-ajax/grid/examples/client/declarativedatabinding/defaultcs.aspx

But for some reason my GetDataAndCount() web service method was never called. The example does not say how the ClientSettings DataBinding properties should be set in this instance, so that might be the problem. How should they be set? Are there any other properties on the grid that need to be set to make this work, or is there a way to tell from the client side object model that the grid is calling the client side data binding function for the second time so that the argument can be set to cancel?

Another related question: I can use

sender.get_masterTableView().get_columns()[0].set_visible(false);
sender.get_masterTableView().get_columns()[0].Display = false;

to hide a column client side during the data binding call. But if I set

sender.get_masterTableView().get_columns()[0].set_visible(true);
sender.get_masterTableView().get_columns()[0].Display = true;

the column does not reappear. Is there another function I should be calling, or should this be done during another event? I would like to manage the visibility of certain columns client side. Is this possible?

I would like to nest a RadGrid within the ItemTemplate/AlternatingItemTemplate of a RadListView and then use a ListView dataitem as a variable for the select statement that populates the RadGrid datasource.

For example:
______________________________________________
User Name: jdoe
First Name: John
Last Name: Doe
______________________________________
|_UserName__|__Workstation__|_LastLogOn_|
|     jdoe           |   PC103              |     8:00 am   |
______________________________________

______________________________________________
User Name: ssmith
First Name: Sally
Last Name: Smith
______________________________________
|_UserName__|__Workstation__|_LastLogOn_|
|      ssmith       |           PC107     |     8:05 am   |
______________________________________

______________________________________________


Is this possible?

Hello,

I'm cannot get my ajaxloadingpanel to appear during an ajax event for my webusercontrol edit for for my radgrid.

My grid is ajaxified by an ajaxmanager and has a specified default ajaxloadingpanel.  The loadingpanel displays during grid sorts and filtering.

I am using an usercontrol as the editform (editformtype=webusercontrol).  The form has several controls on it that I ajaxify by adding ajaxsettings items in the page_load of the usercontrol.  The ajax update behavior seems to be fine (when I change a combo box, the other form controls update the way I want them to).  What is missing is the display of the AjaxLoadingPanel that is set as the default loading panel for the ajaxmanager on the page.

Is there something more specific I must do to get it to display over the updating controls of my edit form ?

Thanks.

Mike

I would like to bind a radgrid that is within an itemtemplate of a list view. Nothing complicated. Just a grid in a list view. The grid will be bound from code behind and really has no dependance on the listview. The listview simply holds the grid.

ASPX:


Here is what I am attempting in code behind:


Any help much appreciated.

I have a rad grid that displays a handful of values IF they exist in the database.  What I want to do is insert a custom row on the grid before any of the data appears that shows the "default values".  Like so,

First row would always show:
<tr>
<td colspan="2">Default Values</td>
<td>Price 1</td>
<td>Price 2</td>
<td>Price 3</td>
<td>Price 4</td>
</tr>

Here are the grid columns:

Hi,
I'm using a radtreeview to navigate records in my RadSplitter. In left RadPane I have a RadTreeView and in the right RadPane I load dynamically pages with. On update I call ajaxManager.ajaxRequest to update radTreeView. However how do I refresh it?

Thanks

I have a Data Grid that currently displays information.   

I have a column named "Status" that displays P, C, or I

I have a Rebind occurring every 15 seconds

After each rebind, or during (not sure) I want to check each row for
the value "P".  If that column Status is P, i want to count it and add it
to a variable.

Once the count is complete after the grid loads, I want to fire off some
script based on the results.

So if there are any values of P in the grid results, I want do something.

How can I accomplish this?   Below is what I started to do, but its not
working right.

Again, trying to loop through EVERY ROW, get the calculated value based
on what the Status is.  If there are no statuses processing, then I will
return a 0 and do something.

What's the best way of doing this?

I have a multiline RadTextBox with enough text to make the scrollbar visible. Is it possible to detect when the user scrolls to the bottom?

I've done this before with a System.Windows.Forms.RichTextBox, which fires a VScroll event.


However, I don't see how to do this with a RadTextBox.
