Hi,

On my tests with drag and drop I am getting the following exceptions which do not seem to be thrown by my code.

The exeptions are "Object reference not set to an instance of an object."

Any ideas?

I'm having a really difficult time getting changes to cell values displayed in a radGrid.

The grid is bound to a dataset containing the output of a SQL Server stored procedure that returns a list of documents.

In addition to the columns that are mapped to particular elements in the dataset (docName, docLocation), I also display a column (status) that is not mapped. 

Here's what I want to do: At runtime, after the grid has been populated, displayed, and the end user has selected several of the rows, I would like to traverse the SelectedRows collection of my grid, set the "status" column value to "S", and have these updated values displayed in the grid:

For Each row As GridViewRowInfo In dgEquiset.SelectedRows

cell = row.Cells("selected")

cell.Value = "selected"

Next

I don't get any errors, but the values don't get set.

How do I go about doing this properly?

Thanks!

i really wish you guys had more info on the shaped form.
how do i add one to my windows project?
i found it somewhere but cant find it again
please help

Thanks for your help,

Hi,

I had used a panelbar with a folder image (open.bmp) with a transparent background with the Q2_2007 release, the folder image transparency worked fine.

After upgrading to the Q3_2007 release, the image transparency doesn't seem to work anymore. Here is what my code looks like now.

this.radPanelBarGroupElement2.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F);

this.radPanelBarGroupElement2.Image = global::MyApp.Properties.Resources.open;

this.radPanelBarGroupElement2.Text = "Folders";

I added the following line to try to get the PanelBar to recognize the transparent color

((Telerik.WinControls.Primitives.ImagePrimitive)(this.radPanelBarGroupElement2.GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(1).GetChildAt(0))).TransparentColor = System.Drawing.Color.Fuchsia;

I also tried setting the TransparentColor of the ImagePrimitive to 

System.Drawing.Color.Transparent

but that didn't work either. Please let me know how to do this.

Thanks,

John Q.

Hi,

We guess there is a bug with "MinSize": (steps to reproduce)
Creat a project with two Docking Panels.
>>One small on the left side - the second filling the rest of the window.
Set MinSize on the left panel.
Make your window large.
Make the left panel as small as allowed in "MinSize".
Now make the Window smaller -- the left panel becomes smaller also.
>>Means MinSize does not work on window resizeing.

The other thing is with the panels background color of panels.
Steps to reproduce:
Again creat an app with two docking panels.
You will see that they change the BackColor to "ControlDark".
In properties use "Reset" to the BackColor -- it changes to "Control" (not bold).
Next run the app -- the panels have ControlDark as BackColor.
>> Check form1.designer.cs to ensure no backcolor is set.
Next close the form and reopen it in design view.
>>Code is added to set the BackColor to ControlDark.

We expect that BackColor work like it does with other Controls.
This means - Inheritance.
And this works well in designer!!

At the existing project change the BackColor of "PrimarySite" to Red.
Next choose "Reset" at the panels -- and YES they are red now - like they should.

Run the app -- again you have ControlDark panels - instead of red ones.

The second is easy to overcome by setting the color of the panel to a specific one.

The first is a real problem.

Hi,

This is just a suggestion: setting GridView.MasterGridViewTemplate.AllowAddNewRow to false when selecting the gridview as readonly.

I cannot really imagine a situation where you would allow a user to insert a record but not be able to update it.

I only recommend this because I could not find the aforementioned property in the properties tab. It would be nice if this property was listed there but that's just me being nitpicky.

Lastly, could please describe how I can go about having a set color for every other row? I would like to have alternating colors for the rows similar to that of an ASP.NET GridView.

Thanks for the help,

Michael
