Hi,

I am using a GridView with a ColumnGroupsViewDefinition, I would like to display only the group headers and hide the column headers, is there a way to accomplish this?

Hi , I'm a new blood in programs. 

recently, I tried to build a RadGridView and fill in data from database

And I create a button if the user wanna export the data in RadGridView 

 RadGridView rgv = new RadGridView();

 rgv.DataSource = dt;

 GridViewSpreadExport spreadExporter = new GridViewSpreadExport(rgv);
            spreadExporter.ExportVisualSettings = true;
            SpreadExportRenderer exportRenderer = new SpreadExportRenderer();
            spreadExporter.RunExport(filegoalpath, exportRenderer);

here is the method i used  , dt has data i wanna export .

so i used rgv to keep the data i wanna export and use these four program to export an excel 

but the program always tell me that my rgv is null and check it cant be null

after i checked , i found that rgv.DataSource really keeped my data in datatable

but rgv.Columns.Count is 0 and rgv.Rows.Count is 0 ,too.

actually this is my first time to write a program in C# 

but i really want to learn it well

so ... hope you can help me to solve my problem :(
plz !!!!

I created some columns, some with decimal values and some with Boolean values.

When I do the bind, every field is fine except the the one with Decimal and Boolean. All my Boolean values are checked, yet after the bind, they show as unchecked. As for the Decimal columns, they are not showing anything at all.

Hello Team,

We are currently building a POS app with winforms and we are wondering if the image attached (Solely the cart list, excluding the headers) can be reproduced?

If yes, how? Any help will be appreciated.

     Hello, 

i'm binding an observable collection of expando objects to a radgridview, each object is supposed to contain a boolean but since i'm constructing my expando object from a <string, object> dictionary the bool property is an object(bool), so when these are displayed with autogeneratingcolumns true i just get a text column with true or false 

how can i display them as checkbox ? 

Thanks by advance.

My range selector represents the 100% length of a running track. RangeStart represents the position of the start line, RangeEnd is represents the end.

I tried databinding to the RangeStart and RangeEnd properties of my selector but, after the initial binding get/set there didn't appear to be any further property change events when I changed the ranges.

How do I bind please?
