Hi,
 
 I am using RAD Grid for displaying and inserting records.

Each row I have one textbox and add button .Using button user can add N number of records.

Let us suppose that user is inserted 4 records(rows).In that 1st and 4 th row data is there 2nd and 3rd empty .If user submit that it shoud throw validation error message.
Let us suppose that in 4 records in that 1nd and 2nd data is there and 3rd and fourth empty ,but in this case it should allow to submit data.

so if there is any empty rows in between it should not allow to submit.But if there are empty rows in last(more than one) user can submit.

Please help me like how i can build the logic

Thanks

Hello Expert,

I am getting an issue in disable auto correction of html element. 
I have a RadEditor where I want to get and set any none valid/formatted html element as like "<noclick> Somethings".
I tried to do this, my code taking none valid/formatted html element as like "<div>Hello World" and giving this same value in server side and I can save this value in database. Then I retrieve this html element from database and bid this html element to RadEditor.Content. But when I browse this page; I can see this value are showing as  <div>Hello World</div> in RadEditor . That's mean its adding end tag to correct html format. But I don't need to add this end tag in my html elements.

Here is my code:

<telerik:RadEditor ID="txtTextScript" runat="server" Font-Size="Larger" EditModes="Html" ContentAreaMode="Div" ContentFilters="None" Height="100" Width="349px">
     <Tools>
              <telerik:EditorToolGroup >
              </telerik:EditorToolGroup>
      </Tools>
</telerik:RadEditor> 

protected void Page_Load(object sender, EventArgs e){
        txtTextScript.DisableFilter(Telerik.Web.UI.EditorFilters.ConvertToXhtml);
}
 
I tried by following this link but still not working

I am waiting for a quick response from someone.

Hello,

I am uploading files using radfileexplorer, images are uploaded in folder, but all images are not visible in fileexplorer even they are uploaded.

any suggestions?

Hey Telerik,

this has probably been answered before but none of the fixes I found seemed to work.

Basically I have a 3 grids in one page and they have quite a bit of data. When I sort/filter a certain column or update a row, 
the page does a postback and goes all the way to the top.

I tried MaintainScrollPositionOnPostback in the aspx page, I tried to set it in the page load and also in the web.config but that didn't work.
I also tried using javascript by having a 'onscroll' event. I tried that on document, window and the wrapping div and the event never got triggered.

The event gets triggered with onmousewheel though, but that wont work with the scrollbar/touchscreen, which I also need.

Is there a way to do a local postback or maybe change something in the grids to prevent going back to the top?

Thanks!

Hi,
I populated my treeview like this


How can I find the checked nodes on server side?

Thanks

I want to filter time duration column in my Grid, which is displayed using toHHMMSS().

The default filter requires input in seconds, so the user have to type 4810  instead of  01:20:10 to represent   1 hour 20 min and 10 secs.

How can I change it to be user friendly?

Thanks.

Hello,I want to add an item to a Radcombox by Javascript.
Here is my code

        function get_data(combobox) {

            var hdcatvalue = document.getElementById("hdcatvalue");
            var combo = $find(combobox);
            combo.trackChanges();
            var comboItem = new Telerik.Web.UI.RadComboBoxItem();

            var request = new XMLHttpRequest();  // Create new request
            request.open("GET", "getvalue.aspx", false);     // Pass false for synchronous
            request.send(null);
            var textval = request.responseText; // '<%=Session["catvalue"] %>';
            var mySplitResult = textval.split("|");
            var gText = mySplitResult[0];
            textval = mySplitResult[1];

            if (hdcatvalue.value != gText && gText != "") {
                comboItem.set_text(gText);
                comboItem.set_value(textval);               
                combo.get_items().add(comboItem);
                combo.commitChanges();
            }
           hdcatvalue.value = gText;
   }
I call the prevous function through OnClientFocus client event

When I try to open the dropdownlist nothing populate (not opened ), but  when I remove:
* combo.trackChanges();
* combo.get_items().add(comboItem);
* combo.commitChanges();

The combobox works fine. Please advice.

Thank you
