Hi!
I have a RadGrid with a checkbox inside a template column. When I place the grid inside a RadWindow and the checkbox is marked as checked in codebehind it don't become checked when displayed. It works fine when it's not placed inside a RadWindow. Anyone has any suggestions?
Example code below.

Hi Telerik,

I'm having trouble with Eval () function in the RadGrid. The function works properly when used like this:


The reason I am doing all this is because I want to know if the unit displayed has a image for it, if not, then I display  error image (using javascript). In order for me to read the directory i have to know the stock number, and that is why I am using Eval Expression in this fashion:


It gives me "System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control." error.

What should I do in order to use the Eval statement?

The code for entire ItemTemplate is here:
 

Hello,

I have implemented the RadMenu on a page with a fixed set of 4 menu items. I have followed an example I found where I set the right click and trigger the client side code to show the RadMenu.  This works great -- especially for an Add,Edit,Delete which applies to all rows. 

How do I further customize this to make it row specific. FOr example, for row 1 I might want to show 2 options, versus row 2, 3 options.  depends on the row.  I thought of using the web service, but passing the row is tricky -- or creating a RadMenu per row --- but before I go down either of these paths I wanted to see if I was missing something and there is an easier way.

Thanks,
Todd.

I have a RadPanelGrid that I dynamically add RadPanelItems from the runtime Page Load. On these RadPanelItems are RadGrids which are also dynamically populated from the original page load. Whenever I click on any RadPanelItem which has a grid on it, I want the item to simply expand and display the grid. It is currently doing this, but then firing a postback which calls the page load again. This means that the "dynamic grid adding code" in the Page load happens EVERY time a click happens (rather than just once when the page loaded), otherwise when I click on a RadPanelItem, it expands, posts back, and my grids disappear.

With my current solution, just clicking on an item causes it to expand, postback, and have the grid re-added, when in reality, if there were no postback, this "grid adding code" would not need to be run every time. How do I switch off postbacks for dynamically added rad panel items? I have tried it at runtime, but it doesn't work, and the documentation does support this fact that it should NOT work, so how should I do it then?

I am already harnessing the client side "OnClientItemClicked" event, as I need to do some client side activity when an item is clicked. I do not however want it to post back server side really, as I already have my grids and display complete, and do not need to. I have read some previous threads suggesting that a: 

e.set_cancel(true);

in the client side function is the way to prevent a server side postback, but it doesn't like "set_cancel" as a property of the event args, and is subsequently giving me a: "Object doesn't support this property or method".

The RadPanelBar is on the form at design time, so if there is a property on there that I can set to stop it doing any postbacks then great, otherwise, it will either need to be a property on the runtime added items, or potentially a "slight hack" in the client side script, to prevent the post back after the click. Any solution suits really, but this continual server side post back is having a huge performace hit on the app, so I need to get it ceased. Any help would be greatly appreciated.

  

Hi Telerik,

I have seen the Documentation for RadGrid usercontrol but sometimes it uses the RadGrid control from the Telerik.WebControls namespace. I am using the RadGrid control from the Telerik.Web.UI namespace.  Could you provide me any posts or links on how to perform add, modify and delete operations on the data in the RadGrid.

Thanks

Hello -
Trying to use the TimelineView -

First Question: How do I set the width of the Grouping column?  (Screenshot #1, the column that says "TP Room" is too small).

Second Question:
I would like the Timeline to show only the availability hours between 7 AM to 23 PM.
I've set DayStartTime="07:00:00" DayEndTime="23:00:00" and also WorkDayStartTime="07:00:00" WorkDayEndTime="23:00:00".
But still when I navigate back 1 day, it will show the hours just before 7 AM (see Screeshot #2).

Also when I use the Date Picker to select a random date, it will display from 00 AM, and not from 7 AM to 23 PM as specified...

Here is my ASP code:

cheers!

Hi

I'm using the filter template and have a radComboBox with a select to display a list of options. What I'm doing id populating the gid with a call to a database, then populating the combobox with another call to the database.

Is it possible to populate the combobox from the already downloaded grid data, this would serve 2 purposes, 1 - one less database call and 2 - the combo box would only have that data which exists in the grid whtout a complcated where clause.

Hi to all!

Hi,

I have a RadTreeView with dynamic items, dynamically added on server-side. The RadTreeView has 2 ContextMenues declared in HTML, on server-side I set the ContextMenueID-Property depending on an attribute from the database (simplified in the example)

If I run the site, I get a Javascript error "menu is null" on line "var items = menu.get_items();"

This used to work before, but I don't know version I used back then.
Now I'm using newest release 2010.1.519(.40)

Here's the aspx-Content:


And the CodeBehind:



Any help is appreciated,

Lukas
