Hello there , 

i have RadGridView hierarchy with 3 level

i want to do the following

1- when expand any row at the first level , i need to collapse any other expanded row.

2-  when expand any row at the first level i need to dispose any data source assigned to other rows , in other words i want to keep my memory to contain only the datasource of current expanded row.

for example

i expanded first row , then rowsourceneed event will be fired and second level will be binded

when expand second row , also rowsourceneed event will be fired and second level will be binded 

now i need to clear the datasource for first expanded row , and when first row expanded again it will force rowsourceneed event to be fired again

please help me.

regards,

Ahmed.

Hi!

I'm trying to filter in a Treeview. The filter is working, but I need to show all the childs from the result-nodes.

I know there is custom filtering, but I have no clue how to do this.

Thanks in advance

I am using Win7 SP1-64. I've had VS 2013 installed for a year or so. I installed a demo version of the UI for WinForms about a month ago. I installed VS 2015 this week, but didn't run it. (Got busy elsewhere.) I removed the demo version of UI for WinForms and installed the licensed version shortly after installing VS 2015.

So, I have both VS 2013 (Pro, Update 5) and VS 2015 (Community) on the PC.

VS 2013 has a Telerik menu and the Telerik WinForms VSExtensions is an installed extension. VS 2015 does not.have a Telerik menu and the Telerik WinForms VSExtensions is not listed.

What do I need to do to enable UI for WInforms in VS 2015? My first inclination is to reinstall it, but I hate doing that without some idea of why it's necessary.

I am trying to use the sechuler to provide just reminders I dont no if i need the full blown component though as i just seen the reminder dialog component however the code is doing something weird but

This is the get all appointments

And if you look in my sql data and my app screen shot its not matching up to whats in the db so it is not i dont understand as displays fine in the web version ?.
