I have  a series of RadDropDownList controls whose contents are dynamically assigned at form load time.  Right after the form loads, and one attempts to select an item in any of the RadDropDownList controls, the control does not respond.  It will display the list of items, but it is impossible to select any of them.  The moving highlight bar does not appear, and the first item in the list remains selected.  However, on the second attempt, and all those afterward, it works correctly.  This is true and consistent for every control of this type.

I have tried various hacks to set the selected index to a different value, and then set it back, but that changed nothing.

I'm using 2010 Q3 (when I upgraded to the 2011 Q1 version the RadTreeView no longer functioned properly and I didn't have the time to figure out why.  All I know is that a call to the RadTreeView.Clear() method caused a null object exception that did not happen with 2010 Q3).

The only event I monitor is the selected index changed event.  I don't need it to fire if the index doesn't change, so there was no need to monitor another event.

All I'm doing on a load is to say something like:

radDropDownList.Items.Clear();

 

 

for (int i = 0; i < matrixDateCount; i++)

 

{

entry =

 

new RadListDataItem();

 

entry.Text =

 

ConversionMethods.GetDropDownListFormatDateTime(this.allMatrixDateTimes[i]);

 

radDropDownList.Items.Add(entry);

}

Any suggestions would be welcome.

Hello, I can't figure out how to change the the page buttons height while in outlook mode.
I've look through the all UI elements but I didn't manage to find anything. Please help me! :)

Thank you.

I seem to be experencing alot of crashes with the Grid.  When I try to click on a filter to start typing in what I want to seach for it will crash the application.

The grids will load just fine and in most cases you can search the first 2-4 cells from left to right, but the closer you get to the right side of the grid the more cells you try to filter will crash the application.

I havent tried any other version yet, any ideas?

(It looks like it could be related to columns that I have moved the position in the property builder from how the query was written?)

Hi Teletik Team. I have an issue that need your help. I has a Form with RadScheduler1 (ActiveViewType=Month). When I run application, It will show RadScheduler on Month View with each header column is the week-date and each header row show the period of day. However, header row show vertical text, I want header row is horizontal  text. What should I do.

Thanks

I am trying to export the grid to an HTML format.I do not want the default export behavior of defining col fixed widths during the export.  I set ExportVisualSettings to false in hopes that it might prevent the use of the fixed widths.  What is the correct way to not have fixed widths exported when working with HTML?

Saludos,


Como estan, tengo un problema. Agrego una columna llamada clnAsignatura al control RadGridview, pero desde el codigo no puedo hacer referencia a la misma por si sola, por ejemplo clnAsignatura.higth.  En el control estandar de vb.net el gridview, si puedo hacer esto, puedo poner en codigo el nombre de mi columna del grid directamente sin necesidad de referenciar el grid. Alguna idea de como puedo hacer esto?


regards,

As are, I have a problem. I add a column called clnAsignatura RadGridview control, but since the code I can not refer to it alone, for example clnAsignatura.higth. In standardcontrol vb.net gridview, if I can do this, I can put into code the name of my column in thegrid directly without referencing the grid. Any idea how I can do this? 

Hi-hi,

After row reorder (sorting in RadGridView), from my code I'm trying to set a value in selected rows.

for(int i=0;i<myGrid.SelectedRows.Count;i++)
myGrid.SelectedRows[i].Cells[0].Value = ":)";

before row reorder (rows sorting from RadGridView control, by pressing on appropriate column) it works.
after reorder - the only first row is available to edit, others are skipped.

Why?

Hi,

I'm using richtextbox with TelerikEditor and have come across the following problem. If I use Text Highlight Color on my text, the highlight color is not saved. ie when reloading the record which was saved in xaml the highlight is gone. Any one else come across this one.

Thanks,
Karl

I have a TreeView that I would like to display a set of objects where they each contain a list<> or BindingList<> of objects of the same type as the base class. It is a recursive type. I am having a hell of a time getting this list to display anything other than the root list. The more I tinker with the ChildMember or DisplayMember I get either nothing displayed or I get an error:

System.InvalidOperationException was unhandled

Hi,

I am currently evaluating the radgridview in UNBOUND mode.

I have used .Relations.AddSelfReference which works in my scenario very well

My question is, is it possible to make the indent smaller for the sub rows

+ My Top Row
        My Top Rows Relation #1
        My Top rows Relation #2

I would like to make this indent smaller

+ My Top Row
    My Top Rows Relation #1
    My Top rows Relation #2

Thanks
