Hi, i have requirement to add Raddropdowntree programmatically to form. Also i am using Load on Demand approach to load data to raddropdowntree because i have more that 40,000 rows of data from sql server. 

but i have a problem here if i hardcode raddropdowntree control in aspx page then load on demand works fine (i have copied that code from user 'Boyan Dimitrov' from telerik forum).

If i am creating raddropdown programmatically in .cs file (see the below code) then that code gives a error 'There was an error in the callback' when i try to expand any parent node.



RadDropDownTree datatreeview = new RadDropDownTree();
datatreeview.ID = raddptreename;
datatreeview.Attributes["CssClass"] = "radwidth";
datatreeview.Attributes["runat"] = "server";
datatreeview.Attributes["OnLoad"] = "RadDropDownTree1_Load";
datatreeview.EmbeddedTree.NodeExpand += embeddedTree_NodeExpand;
form1.Controls.Add(datatreeview);
loadtreeview(RadDropDownTree1, TreeNodeExpandMode.ServerSideCallBack);


Please guide me in fixing this problem.

Hi,

I want to make a multiple sorting + natural sorting column. Multiple sorts are working fine but not for natural sort.

May refer to attached image.

Thanks.

Hi everyone,

 

I have a RadGrid with batchedit mode in a usercontrol, and I want to have different editors based on the type of the parameter. For example : if the parameter is a string, the editor should allow to write strings, or datetime, boolean, integer, even files so the user can download the file and also images so they can appear on the radgrid !

I found something similar to what I want but it's using Kendo UI : https://docs.telerik.com/kendo-ui/knowledge-base/grid-different-editor-based-on-column-value

Any suggestions ?

 

Thank you

Hello...I am using the latest build of Promethius controls. My problem is with the Rad window. I am generating a large page which loads variable numbers of images in various sections. These images are enclosed in links which invoke the RadWindow so that the images can be viewed in another image viewer control. That all works fine...However, as I mentioned, the page can be rather large, so for example if I scroll to the bottom of the page and click on one of those links, then the parent window scrolls automatically to the top before displaying the radwindow...worse yet, since the radwindow opens relative to where it was clicked, then the window is completely out of view and the user must scroll down to see the popup. The only thread I found that comes close to addressing this is http://www.telerik.com/community/forums/thread/b311D-bahgmt.aspx but did not solve my problem.
This behavior is the same in IE, FF, and Safari.
A temporary work around is to do a MoveTo and move the window to the top of the page, but I would prefer that the main page stay in place and the the window open where it was clicked...so that when the window is closed, the user doesnt have to scroll back down to where they were when they originally clicked on the link....make sense?
Any help on this would be greatly appreaciated.

Thanks!

Hi All,

I use Teleriks controls for asp ajax and have a question regarding the
skin files...

I've copied the Skins folder to my project folder and have included it
in my project, but almost all of the items in these folders have a
"Build Action" of "Content" and a "Copy to Output Directory" value of
"Do not copy" in the properties window.

Do I have to go through all these folders to change the "Copy to
Output Directory" to "Copy Always" to ensure all my skin items are
copied over when I publish or build my site?

Of course, this question relates to any file that gets included to a
project, not just Telerik skins...

This page (http://msdn.microsoft.com/en-us/library/0c6xyb66.aspx)
suggests that the "Build Action" - "Content" that...

"The file is not compiled, but is included in the Content output
group. For example, this setting is the default value for an .htm or
other kind of Web file."

but this page also states the seetings for "Copy to Output Directory"
are ...

"This property specifies the conditions under which the selected
source file will be copied to the output directory. Select Do not copy
if the file is never to be copied to the output directory. Select Copy
always if the file is always to be copied to the output directory.
Select Copy if newer if the file is to be copied only when it is newer
than an existing file of the same name in the output directory."

If I do have to set all my content skins and images etc to "Copy
Always", is there a quick way to do this when there could be hundreds
of these files spread through a large number of folders and sub
folders?

I am trying to get the value of selected item from a RadDropDownList using the below code snippet:
ddlEntType= '<%= rddlEnterprise.ClientID %>

but it is giving me "undefined" as the result.

Can you please provide the solution for this?
