1. i have one radtextbox and radbutton. i want to make this radbutton visible when people start typing. if there is no values in the radtextbox radbutton should be hidden. so when started entering the letters radbutton should be visible and when they delete or backspace completely then radbutton should be hidden?
i tried so many ways to achieve this task from client side.

what is the java script code for this one. it should support all browsers. i tried onkeypress. but didnt get the result i want.


2. i want when user remove selected files from radasyncupload then radbutton should be hidden. when they start selecting files to upload then radbutton should b visible.
 when i selected removeselectedfiles option, button become hidden immedieately remove just one file itself. hwo to check the number of files selected in radasyncupload from client side ?

3. is there any textboxlist control in telerik for email text field? i want like to see as iphone, facebook and all. how to do that?

Team,

I am having one major issue i radgrid.

In grid i m selecting 2 rows and now filter with some values then i am select 3 rows. Now i need to click  on add button which is outside of grid. But in result grid only 3 rows will be added. Expected result grid should be  add all selected rows i.e. 5 rows.


Please help urgent.

I've already looked at:
http://www.telerik.com/help/aspnet-ajax/grid-appearance-customize-gridtemplatecolumn.html

Which used a template for the header and data sections.  To my eyes its a really crude solution, and doesn't look very good.

Is there a better way to do this that reflects a polished product?

Thanks

I have this aspx:

 And my code behind is like:

When I click on the button, the label "lbl" disappears (it should change the text of the label). Should I use two panels? or how can I ajaxify the asp controls?

Thanks in advance

Hopefully this is a simple issue/rookie mistake. We have a RadGrid where our header row is not showing at all. I don't know why, but it appears that the css class "rgHeader" is not attached to the th. Any thoughts on how to fix this or where to even start troubleshooting? We have this code working as part of a larger project on other machines (where the header correctly gets the rgheader class). We can't rule out that it's a machine issue or that something is missing that was included in the larger project. Image of missing header row attached (note we purposefully loaded two empty rows of data, so we know all the data is loading correctly) as well as grid definition and rendered html.

Rendering:

All Im trying to do is pass a default value to the bound EDICustomerID feild so that when a new code is created via the radgrids 'add new record' it gets the value from the querystring Which holds the EDICustomerID that all codes belong to. 
What is the cleanest / best practice way to get the default value to be a value from the querystring?

I tried the following but while it didn't throw an error, it didn't work, either:
ASPX:

objectDataSource(c#):

And finally the object its self:

I have a screen where I have a treeview that loads 

 foreach (var user in allUsers)
            {
                var claims = db.AspNetUserClaims.Where(c => c.User_Id == user.Id);
                foreach (var claim in claims)
                {
                    if (claim.ClaimType == ClaimTypes.Role)
                    {
                        for (int i = 0; i < UserTree.Nodes.Count; i++)
                            if (claim.ClaimValue == UserTree.Nodes[i].Text)
                            {
                                var userNode = new RadTreeNode(user.UserName, user.Id);
                                UserTree.Nodes[i].Nodes.Add(userNode);
                            }
                    }
                }
            }

This loads fine when I click  + for the parent it expands to show the children.  This all works the issue is on the NodeClick event.  The very first time I click on a node it reloads the page and never runs the NodeClick Event.  After this one time event everything works properly.  I can expand and contract nodes and when I click on a node it rune the node click properly.  It is just the initial node click after the page loads that has this behavior.

Hi Gurus,

  I am dynamically calling a usercontrol,

  my issue is,when i click the paging button,the control is not loading (i need to use custom paging not built in paging)

Here is the code:

Thanks in Advance

Hello, the bug is very easy to reproduce. This is the 4th bug I've found with decorator in one month after start using it with Lightmode rendermode, evidently it is flimsy and needs testing.

.aspx



.cs

I am begging for some kind soul to help me here.

I have tried everything I can think of, and I haven't been able to fix this problem.

For some reason, some appointments appear perfectly fine on my Scheduler, and others get cutoff. The code is exactly the same for both appointment creations.

Note: I am creating appointment manually and using the InsertAppointment() method to add them to the Scheduler.

I thought that maybe it was affecting only appointments scheduled in the future from the current date...but when I moved appointments around, I found (as you will see in the attached image) that I was able to see appointment perfectly from the 5th (current date) to the 9th. But starting the 10th, it gets cutoff. It's so BIZARRE...

PLEASE PLEASE Can anyone help me fix this?
