Hi,
I found some issue. I am using BindingList bounded to RadGridView.
Using memorystream to save and restoree layout of grid.

Problem is that when i am using grid.LoadLayout(ms); layout is loading well but there is some problem with groups
Look at 2 pictures
11.png - after LoadLayout
12.png - after group header click ( status )
When i change sorting groups are displayed well.

Using nevest telerik Q3

I have a DockPanel docked to the right in a docking manager.

The DockPanel is AutoHide. When I move the cursor to it and it is opened, the width is very large. Is there a way to set this width?

If I dock the DockPanel the width is what I've set the DockPanel.Size = new Size( width, height) to be.

Hello,

My test app, is a WinForm application:

I have a column in a DataTable named "my]field". I also have a RadGridView with the "EnableFiltering" property set to "True". I assign my DataTable to the DataSource of the RadGridView. At runtime, when I attempt to set a filter on this column, I get this error: "Syntax error: Missing operand after 'field' operator."

Any ideas how I can have a "]" character in a column name and the filtering still works?

Thanks,

Hello,

Hi,

I want to have a grid with a combo box column, but for each row, I want to apply different DataSource in the combo cox. The values in the combo box are depending on another column value for each row.

I can't use the MasterGridViewTemplate, because it's applying the SAME datasource for each row, so what should I do?

Hi, I'm currently trying the charting component in my winform application. (version 2009.1.9.316)
Now I've got just a treeview and a chart component on my winform.
when I click on a treenode the chart view is loaded with the data, everything works fine.
now as long as my treeview isn't reloaded the chart loads the data, but when in my main form is triggered to reload the treeview and I click a treenode, my program crashes. with the following exception:

general exception:    at Telerik.Charting.Chart.GetException(RenderEngine renderEngine, Exception ex)
   at Telerik.Charting.Chart.GetImage(Int32 width, Int32 height)
   at Telerik.Charting.Chart.GetImage()
   at Telerik.WinControls.UI.RadChart.GetImage()
   at Telerik.WinControls.UI.RadChart.OnPaint(PaintEventArgs e)
  
in the innerexception I'm reading system.nullreferenceexception
   at Telerik.Charting.ChartSeriesItem.set_Parent(ChartSeries value)
   at Telerik.Charting.ChartSeriesItem.Clone()
   at Telerik.Charting.ChartSeries.CopyItems(ChartSeries originalSeries)
   at Telerik.Charting.ChartSeries.CloneSeries()
   at Telerik.Charting.RenderEngine.InitializeChartElements()
   at Telerik.Charting.Chart.GetImage(Int32 width, Int32 height)

how is this possible? I didn't found anything bizar in my code. I added a try catch around the code that fills the chart, but the error isn't triggered here, but in my main try catch of my program.

my code:


The function TheIO.GetDataChartHistoricMonth or TheIO.GetDataChartHIstoricYear are returning a list of ChartHistoric


Thanks a lot

What is the best way to have multiple column heading rows but only single data rows?  For example:


I don't have a data column for Service, for example. That is just a way to show the user how the Qty & Desc columns are grouped. I tried the ColumnGroupView but did not see a way to create the sample above since the Item column seems to need a parent group.

When I try the HTMLView apparently I need to add unbound columns to the grid or else I cannot format the headings. Specifically this line of code fails if I do not add dummy columns for the extra group (like Service above):

GridTableHeaderRowElement

 

header = (grid.GridElement as GridTableElement).TableBodyElement.Children[0] as GridTableHeaderRowElement;

 

 

 

 

 

The Children collection is empty.  If I DO add dummy columns to the grid to make the headings work then my data rows have mutiple rows. In the example above, a text box appears in a row above the 4 and Quarts columns representing Service which we don't want.

Anyway please let me know if I'm missing something obvious to make this work.

Hi there,

I was hoping you could shed some light on how I could add an image to a Command Column.  Currently my command column contains a button... but I would like it to contain a nice little edit image instead.

Any ideas, or sample code?

Thanks for you help.

Hi Telerik

We have the same problem as "PunjabiSingh", but different at some point

Our problem as below:

We try  to use "Hierarchy (Master-Detail Layout) with Tabbed Child View" to list all the information in one folder (including sub-folders and files). If there is more files under sub-folder, we can use "+" to explore this folder. (It is greate). If there is nothing in sub-folder, we also get a blank grid which the coulum name the same as others. But I think it shouldn't appear "+" at the right of the folder which don't have files in it.

Do you have any other control to avoid this problem?
