Trying to use the Radgrid to do server-side data filtering.  

I'm binding a dataset to a RadGrid, and setting the AutoPostBackOnFilter='true' for each column.  Clicking on the filter button throws this unhandled exception.

If I use DataBinding to create my menuitems, and use the OnClientItemClicked event to call a javascript which calls a radwindow (popup), the called radwindow does not popup, rather it loads into the target pane.
(well it pops up briefly, then exits and reloads in the Target Pane)

However, when I Create the MenuItems in HTML, the call to the OnClientItemClicked javascript , does popup the radwindow correctly.

My workaround for this was "AppendDataBoundItems" and retain a menu item from HTML, such that my popup radwindow pops up correctly...Happiness,..BUT

It is AppendDataBoundItems,...and I really want PrePend,..i.e. I would like my MenuItem with Popup to appear at the end of the Menu, not the beginning.

Any help,..ideas ? (for either).

Code is: 

Markup is:

 

telerik:RadMenu ID="RadMenu1"  runat="server" Width="100%" Height="31px" Skin="Black"

 OnClientItemClicked="MenuItemItemClicked"

 DataFieldID="ScreenId"

 DataNavigateUrlField="Screen"

 DataTextField="Title"

 DataValueField="ScreenId"

 OnItemDataBound="RadMenu1_OnItemDataBound"

 AppendDataBoundItems="True">

 <DefaultGroupSettings Flow="Horizontal" />

 <Items >
      <telerik:RadMenuItem runat="server" Text="Login" value="Login"

                  BackColor="Transparent" ForeColor="#FFFFC0"></telerik:RadMenuItem>

</Items>

I have a maskedTextbox with 2 events, onblur client side and OnTextChanged in server side.
My on blur method are returning true or false, if my return is true, i wanna enter in server side and do OnTextChanged, if return is false doesnt enter on server side and show a alert. 
My problem is, my return can be true or false, doesnt make anything different, always enter in server side.



Thankz in advance!

I have radgrid which I am binding with a Webservice on the client side.

This is what I want to do:
I want to create a GridTemplateColumn or a GridButtonColumn, when clicked should show a RadConfirm and when clicked "YES/OK" on radconfirm should call another javascript function without doing a postback(or page refresh). Other wise should not do anything.

This is what I have done:
Mark up for the grid template column.

Javascript on Row DataBound:

This is the showDeleteConfirm method:

But everytime I click on the button, it does a postback without calling the javascript function. Help will be appreciated :)

Thank you.

Hi all,

Im using the latest telerik rad ajax controls (ASP.NET AJAX Q1 2012 version 12.1.215.0). I have a treelist which has a template column whereby I placed a combobox in it. What my page does is I allow the user to select options in the combobox and when they click the save button, my function will create 1 record per row which has a selected option in the comboboxes. Here is my code

A little explanation bout my  page is onpageload if there is an existing data in the database I will populate the treelist and also bind the comboboxes in the treelist based on the value saved in the database (this works fine). But my problem now is when I select a different value and click the save button, it is supposed to create a row in my database table with the new combobox selection however it doesnt.

As you can see, I bind my comboboxes in the itemdatabound and in my Save function what I do is I clear my database table and then I reinsert new rows into the table based on rows in the treelist which has a selected value in the combobox. As for now I am only testing based on ddlGoalStatus combobox so please ignore the ddlInterventionStatus combobox. In my save function, I have a line which says "string s = ddlGoalStatus.SelectedItem.Text;" and the value I retrieved is ALWAYS the previous value and not the newly selected value. Am I doing anything wrong? 

Please help.

Thanks!

Hi!

I found a good article that allows us to programmatically set the invalid state on a text changed event (the code is reduced for brevity).

The results of this code is shown in image 1. However, we do not want to validate until a submit button is clicked on a form. We did something like this (note--code is in flux):

The results are shown in image #2. As you can tell from the second set of code, we were trying different ways to reference the controls, but we could never seem to get the controls to visually update. In the first scenario, the "sender" variable is passed in, so is something going on under the hood that allows the updateCssClass() method to work ??? Is this possible outside of a change text event?

Thanks!

step 1 <<img
design two radnumberic, left control not set readonly and right controls set readonly = true (both set value = 55.55, 22.22)

Step 2 << img
when click mouse down on right textbox, the value have double

Step 3 << img
when mouse up, it look like textbox multiline

i'm using v2012 Q1 and run on IE8 i see that case, but in Chrome(v17.8.963.83) FireFox(v11) and Safari(v5.1.4) i can't focus on radnumberic readonly it look like disable control

radnumric readonly in this version cann't focus the value from textbox ?
how can i solve this problem.

Sorry for my poor eng, - -'
