[Solved] RadNumericUpDown - Value format

I have a RadNumericUpDown control that's *typically* used for integer input. However, on rare occasions, there is a need to enter a floating point value with up to 4 decimal digits - the bound property is actually a FLOAT.

I know I can configure the control with "NumberDecimalDigits=4" and it will work as expected. However, I dislike the trailing ".0000" that's displayed when the control is being used to enter INT values, which again, is most of the time.

So, is it possible to configure the control to *allow* decimal digits to be entered, but to not display them unless they exist? So, if I enter an INT, I want it to be displayed as an INT (no decimal digits), and if I enter a FLOAT I want it to be displayed as a float - with all entered decimal digits.

Thanks,

Jeff

Buttons within DropDownItemTemplate

hi,

I added two buttons to the DropDownItemTemplate, one of them will do the select item, and the other one will just do a popup. I found that the click event I added to these two buttons in the template never get triggered except for the "SelectionChanged" event from the RadAutoCompleteBox when I click on the item.

Is there anyway I can get those two buttons to work inside the DropDownItemTemplate?

thanks in advance

Iterating the Grid rows and columns is very very slow

Hi
I am iterating through the rows and columns of the grid view like this :
foreach (var row in radGridView.Items)
{
foreach (var column in HeaderInfo)
{
string sUniquename = uniqueNames[iColumn];
var boundColumn = radGridView.Columns[sUniquename] as GridViewBoundColumnBase;
if (boundColumn != null)
{ string data = string.Format("{0}", boundColumn.GetValueForItem(row));}
iColumn += 1;}}
The thing is that its too slow ...for a grid with say 80k rows it is taking 5 minuted to complete this loop...I guess internally it is building up the rows internally as our grid has virtualization enabled.

Please suggest if something can be done on this.

Cell FillColor

Hello, I'm customizing the cells to have rounded corners. I'm using the code from here. http://www.telerik.com/forums/rounded-cell-corners
Is it possible to to have the selected cell only fill the part with the rounded border, instead of the whole cell. See attached for what the control currently does. You'll see that it bleeds out into the rest of the cell.

Thanks,
Scott

[Solved] Display specific string for NULL cell value

I'm using RadGridView to display DataTable.DataView collections. In the underlying data, it's perfectly valid for some of the fields to be null. However, rather than simply displaying those fields as a "blank" cell in the grid, I'd prefer to display a predefined string (say, "<null>" for example). Is there an easy way to accomplish this?

One possible restriction on a solution is that the grid is used to display "random" DataView's and auto-generates the columns for each. So, the solution would need to work in that circumstance.

Thanks for any advice.

Issue in Adding tab items at run time

Hi Team

I have a radtabcontrol.Items source bind to some collection in ViewModel. Each tab item has its own view and VM. I am adding multiple tabitems to the control at run time. Steps are :
1. create the instance of the view model of the tab item
2. Add it to the collection in the VM.

After this , the tabcontrol shows the desired tabs. The issue is that the view of only last tab item is initialised , other tab items views remain uninitialised. I need to select each tab item one by one...only then the view is getting initialised.

I need to read some control info from each tab item view model...for that i need each view to be initialised without manually clicking them one by one.

Your WPF/Silverlight online documentation site sucks

It is always a pain to use your wpf and silverlight online documentation. Wouldn't it be possible to separate the left and the right part, to scroll each other independently?

For example, when I use http://www.telerik.com/help/wpf/n_telerik_windows_documents_formatproviders_pdf.html and click on classes or properties I loose the context of the namespace, because I always have to scroll all the way down to get it back into my view.

I wonder why nobody complains about this? How do others learn about the features of new controls? Or do I miss something?
