Radgrid in master page does not update when the form template is contained in the content page

Hi,
I have a master page with a grid that inherits the form template from a content page. The fields are displayed correctly in edit and all valued but when I press update it says that the fields cannot be null.
This problem occurs only if the form template is on the content page while if you put the template directly on the master page then everything works.
I used a code similar to the demo https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/form-template-update/defaultcs.aspx as an example.
What I do wrong and how I can fix it?
Thanks

Default template for NextPrevNumericAndAdvanced pager

We use the NextPrevNumericAndAdvanced pager, and need to add a textbox / button similar to Page Size, which we want to use for number of rows displayed (effectively changing grid height)

I'm guessing we need to use a custom pagertemplate, but don't want to try and recreate the NextPrevNumericAndAdvanced from scratch, so do you have the html content for the default, so that we can modify that?

Handling Null Values when Sorting
One of our testers just caught an issue with RadGrid where Oracle is returning the data set sorting NULL values last.  RadGrid, however, is positioning null values first.  It appers to be an option on the Oracle side that can be controlled.  In our app I think the thing that makes sense is to sort the null's last.  Is it possible to modify the RadGrid behavior to treat NULL values in this manner?

Thanks,
Colin

Tag or keyword editor?

I'd like to create a tag/keyword editor similar to the one used on sites like StackOverflow, where tags are formatted differently into the textbox and autocomplete is available as the user types (see attached screenshot).

What's the best way to do something like this with Telerik UI for ASP.NET?

Enable rotate option

Hello Telerik-Team,

I am trying to find a way to enable rotate option in diagram.
Saw this example: https://www.telerik.com/forums/shape-rotate-style
There you can see a rotate button, but on my project rotate button doesn't appear.

A toolbar like in kendo ui would be even better as the aspnet variant is based on kendo.

Regards

RadGrid doesn't sort a column populated in ItemDataBound

Hi, i've a problem sorting a RadGrid

When i try to sort, rows data are sorted all except the last column "Allegati" that remains fixed. That column is compiled on the ItemDataBound event, based on the datatable. How can I correct this behavior? Radgrid is under Ajax. Thanks

RadScriptManagerProxy and user control
Hi,

In my User Control I got a ScriptManagerProxy with a ScriptReference property in which I load a Javascript file.

 

<asp:ScriptManagerProxy ID="smp" runat="server">  
    <Scripts> 
        <asp:ScriptReference Path="~/Scripts/myScript.js" />    
    </Scripts> 
</asp:ScriptManagerProxy> 

This Javascript file contains this function:

 

function onNodeClicked(sender, args) {  
    ...  
} 

Finally, in my User Control, I have a RadTreeView:

<telerik:RadTreeView ID="myTree" runat="server OnClientNodeClicked="onNodeClicked"> 
    ...  
</telerik:RadTreeView> 


This control is loaded dynamically in a aspx page. When I execute this, I receive this message:
                
                            Microsoft JScript runtime error: 'onNodeClicked' is undefined

What's wrong ?

How to keep scrolling page while dragging Tree node until certain event

While I am dragging a node from a RadTreeView, I want the page to scroll up or down when the element hits a certain position on either the top or bottom area of the inner height of the page.

The best solution thus far has been this post: https://www.telerik.com/forums/radtreeview-drag-and-drop-scrolling

01.function nodeDragging(sender, args)
02.        {
03.            var container = sender.get_element();
04.            var divYCoord = $telerik.getLocation(container).y;
05. 
06.            var currentYCoord = args.get_domEvent().clientY;
07.            var textbox = $get("textbox");
08.                     
09.            if (currentYCoord > (document.body.clientHeight - 20))
10.                window.scrollBy(0, 20);
11.           
12.            window.status = "document.body.clientHeight:" + document.body.clientHeight + ":currentYCoord:" + currentYCoord + ":document.body.scrollTop:" + document.body.scrollTop + ":iTop:" + (currentYCoord - document.body.scrollTop) + ":" + args.get_domEvent().screenY + ":" + divYCoord;
13.            if(currentYCoord < 20)
14.                window.scrollBy(0, -20);
15.        }

 

I placed a code in a client node dragging function, but the issue is that the scrolling only happens once until I move the cursor again.

I would like to know if there is a way where the page continues to scroll while the dragging tree node remains within an area of the page.
