Good day to forum members!

I have such a question-

what operations can I do with tags like #=dataitem.value# ?

In demos I saw expressions like 

#=dataitem.value + dataitem.value1 + ...# 

So, what else can I do with these ones?

Can I use any math function?

Can I round result?

One yet thing - can I work with #=dataitem.value# like operator in my .cs file? For example, convert it to value type? Something like decimal d=Convert.ToDouble("#=dataitem.value {0}", 1); ?

I'm not successful in any of these things;

Sorly, I'm new in telerik and ASP.

It seems empty message for ComboBox with check items does not work.

Even though I have added a property of EmptyMessage="Select", my still shows nothing instead of Select.

How can I make default message show up when no item is selected?

Here is my code

Is there a way to retain the width of columns in a radgrid after resizing one or more columns?  After resizing one of the columns, if I do anything, such as navigate to the next page in the grid, then the resizing is lost and all the columns are back to the original size as if I just accessed the page.

Thanks!

Hi,

could somebody help me with setup of RadGrid in this demo? RenderMode is Mobile, I know but how to get the "inner scroll with auto min width" behavior. Thanks a lot

All,

I have a pretty simple grid setup (see grid code below). When I try to export to PDF I get the exception below. I can't register the controls because I only have reference to them during "ItemDataBound" event.

What's the work around on this one?

Here is my RadGrid Markup

Export button code

Thanks in advance!! 

I have created a RadGrid.  Here is the steps I used to create it and then remove all the rows (I just want the header - details why below)

I clear the rows in the datatable that I bind to the grid

I set the RadGrid datasource = to that blank datatable

I then bind

I also set the NoDetailRecordsText = "" and NoMasterRecordsText = ""

I have column headers that are dates (1/12 for example) and each day they change.  Those are in the middle of the columns.  All the other columns have named headers I know about (except the dates)

Column layout

Hardware Model 1/2  1/3  1/4 Col1 Col2 etc.

I need to set all the columns to a value (only way i know to set those date ones but code I have tried does not work) in ItemCreated event

For Each col As GridColumn In grdHeader.MasterTableView.Columns                 

     col.HeaderStyle.Width = "60"             'Never gets to this

Next

then go and set the rest of the column widths (this seems to work)

Dim gridCol As GridColumn             

gridCol = grdHeader.MasterTableView.GetColumn("Model")        

gridCol.HeaderStyle.Width = "140"

The reason I need to do this is we have scrolling RadGrids per group and I want to keep the header above the scrolling section as when it scrolls each header for each grid goes away and you have no clue what cols go with what data.

I hope this give enough to hopefully point me in the right direction.

I appreciate any help
