Hi,

I have 3 different RadComboBox within GridTemplate column. I'm trying to build a cascading hierarchy upon the selection of each RadComboBox.

Within the code behind........onSelectedIndexChange of the 1st RadComboBox........I need to find the 2nd RadComboBox so that I can set the displayed value and text.

 

 

protected void ComboBox1_OnSelectedIndexChangedHandler(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

 

{

Session[

 

"ID"] = e.Value;

 

Session[

 

"Text"] = e.Text;

 

 

 

//Since the Area has been changed, we set the FMT RadComboBox

 

}

thanks,
Minh Bui

Hello

I'm getting value of a cell in selected row in RadGrid. I have enable Client-Side Row Selection and PostBackOnRowClick.



And from code-behind, I get the value of the cell with this code snippet in ItemCommand event:


And it did work. 

But when I put my grid in to a RadDock, then SelectedItems always return 0.

I don't know why?

Can you help me explain this problem?

Thank you.

I've encountered another development issue, which I believe is AJAX-related.  I've several controls (views) that are loaded into a multipage upon page Load.  These controls are navigated via tabs in a tabstrip.  Each view is divided into two parts via ASP update panels:

1. A toolbar (Toolbar_AjaxPanel)
2. Content affected by the toolbar, which contain a series of web user controls  (Content_AjaxPanel)

One of these web user controls is a catalog that lists programs.  A program in the list can be selected, and this raises the OnCatalogItemSelected event, a custom event which is triggered by the OnSelectedIndexChanged event of the RadGrid within the catalog web user control.  The OnCatalogItemSelected event runs a few checks and sets some visibility settings before updating the content panel via Content_AjaxPanel.Update().

Everything appears to work as expected until I click a tab and switch to a different "view."  When I do, I receive this client-side error:

Error: Unable to get value of the property 'paste': object is null or undefined

The application does not appear to be adversely affected, otherwise, but this error might confuse users.  From what I can tell, it's the Update() call in the OnCatalogItemSelected event that causes this to happen.  When I remove or comment it out, I no longer receive the message, but I need that Update() call to refresh the content and display the appropriate controls.

Here is the code that handles the OnCatalogItemSelected in the ProgramView.ascx view:

And if you need it, here is the interface markup:

If you need anything more, please let me know.  Thanks.

Hi,
I have treelist.it has nodes.when i click to expand the treelist it behaves i selected it.but i dont click select button i only click the + icon on treelist.this is the code which i tried.

if (dataBoundItem.ItemIndex > 1) 
                {
                    e.Item.ForeColor = Color.Red;
                    if (Decimal.Parse(dataBoundItem["pcntchg"].Text) < 0) <<How to get the value here without using column name, I can't see how.
                    {
                        dataBoundItem["pcntchg"].ForeColor = Color.Red;
                    }
                }

How to select new window option for ddl when i click on hyperlink image for creating hyper link the new window popup is open there is a ddl for target inside this ddl how i select new window option by default.

Hi,

I have some submenus off a main structure.  The code is below.  When I mouseover back and forth from the main menu to the submenu the overall menu height keeps changing. It shrinks when I move towards the submenu and gets back to original size when I come back to the main menu.  This is a sample HTML I put together, the issue happens when I move between "View" and "Recent" back to Searches in the main menu.  The CSS I am using is at the bottom of the HTML.

Hi there, i'm wondering if this is possible, what i'd like to be able to implement is a radcombobox where it finds the closest match to whatever you type.

For example i've got a radcombobox with markfirstmatch enabled and allowcustomtext to false (because i want to limit them to the items within the combobox). 

Take this for example; a combobox populated with countries. 

United Kingdom 
United Arab Emirates. 

I start typing 'Uni' and it jumps to any items starting with 'Uni' which is great. However, what if i want to type 'Kingdom' ? Or 'Arab' , or any part of the text. 

I'd like it filter the items in the combobox based on this. 

Another example would be me typing in 'land' and having it find 'England', and any other items containing that text.

Many thanks for your support Telerik.

I have a nested grid view in radAjaxPanel. In parent grid, there is one division, in which I am adding linkbuttons runtime on _ItemDatabound. I need to open picture files on click of the link button click.
Like, div in <itemTemplate>


And on server side, on _ItemDatabound event, I am adding link button and assigning click event of that.


The whole grid is inside RadAjaxPanel. So, as i need to open image on click of the linkbutton,



But it never calls the "attach_Click" event on click of the link button.
This works perfect outside the radGrid.
What's wrong with this code?

I am using Telerik RadControls. I have radGrid in which i have upload control for inserting images. But error is thrown when I try to upload any file.
