Visual Studio Memory Increase due to Visual Style Builder

Hello,

I recently upgraded to 2009 Q2

As I've been working on getting my themes right for a gridview, I've opened the Visual Style Builder and closed it several times. The memory footprint on Visual Studio has increased to over a gig, and I can see it increasing without decreasing often when I open/close the VSB. Just an fyi.

Thanks!

DataNavigateURL to get DataFieldId as parameter

Hello,

I have something I am sure has been done 1000 times before but I couldn't find a sample. Databind a menu but I want to pass the DataFieldId as a parameter to my destination page of the menu item being clicked. For example:

Menu option Products
Sub menu options of all product catagories

If I click a product category, I want the destination url to be "ShowProdsInCat.aspx?ProdCat=XXX" where XXX is the ID of the menu option clicked. How do I best set this up? Should I update the destinationurl in the ItemCreated event?

Thanks,
Paul

How to hide the Display Member column

Hey guys,

I'm using the MultiColumn ComboBox to select an item for editing. The ComboBox ties into a DataTable. That DataTable has the following columns of interest:

1. An integer column, "id", the primary key.

2. A string column, "code"

3. A string column, "description"

4. A string column, "display"

There are other columns, but they're not important.

The "display" column is calcualted by a SQL statement before it gets to the table - the Column itself doesn't understand that it is an expression column.

I want the "display" column to be the DisplayMember. But I do not want that column to be visible when I use the Drop-Down of the comboBox.

When I get the gridView inside the Drop-Down, and set the "display" column .IsVisible = false, the column goes away from the Drop-Down, but the DisplayMember no longer works. I get the "code" column, not the "display" column.

Is there a way to hide the column used by the DisplayMember? Or will I have to assign it manually every time a new row is selected in the Drop-Down?

After I changed backcolor of GridHeaderCellElement in Element hierachy editor and press F5, an ArgumentOutOfRangeException was thrown. (The exception occured in this piece of code:
((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).TextAlignment = System.Drawing.ContentAlignment.MiddleCenter;
((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).Text = "CustomerID";
((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(169)))), ((int)(((byte)(20)))), ((int)(((byte)(20)))));
)
I've strugged with this problem all day. Please help me.

Completing a New Row in Unbound Mode

Hi,

Does anyone know how the user is supposed to "commit" a new row in unbound mode ? I constructed a simple project with a three column grid and ran it - I clicked on the "add new row" line and entered some data. Now what ? I cannot add another row as the "add new row" pseudo-row has disappeared. Clicking on the "pen and paper" icon on the left just switches the row icon to a "*" indicating that I'm still in new-row-edit mode. The only way I can find of actually committing my new row is to click on a column header button (even tabbing to another windows control doesn't seem to commit my new row).

I must be doing something wrong here, but I've searched the forums and pretty much every property I can find on the RadGrid but cannot do this simple thing. Must be a bad day for me <grin> . Seriously though, can anyone help with this trivial task ?

Appearance is being ignored

I'm using the RadChart from 2008 Q2 SP1.

Nothing I do to change the appearance in code causes the style information to change. I've tried with and without DataBind(), and I've tried changing the style informaiton in the designer as well as writing the code explicitly. It always reverts to the basic empty skin.

Here's an example:

    
            var series = chart.Series[0]; 
        
            var appearance = series.Appearance; 
        
            appearance.PointMark.Dimensions.AutoSize = false; 
        
            appearance.PointMark.Dimensions.Width = 2; 
        
            appearance.PointMark.Dimensions.Height = 2; 
        
            appearance.PointDimentions.AutoSize = false; 
        
            appearance.PointDimentions.SetDimensions(2, 2); 
        
            appearance.LabelAppearance.Visible = false; 
        
            appearance.TextAppearance.Visible = false;

Note that I'm using a Point chart.

Any ideas what I could be missing?

	var series = chart.Series[0];
	var appearance = series.Appearance;
	appearance.PointMark.Dimensions.AutoSize = false;
	appearance.PointMark.Dimensions.Width = 2;
	appearance.PointMark.Dimensions.Height = 2;
	appearance.PointDimentions.AutoSize = false;
	appearance.PointDimentions.SetDimensions(2, 2);
	appearance.LabelAppearance.Visible = false;
	appearance.TextAppearance.Visible = false;
