Visual Style Builder Preview Mode Not Rendering

Hi,
I can't seem to get the preview in the visual style builder to render my updates. It always shows the default theme.
Most of my testing has been with the GridView control.
I'm running Vista, and Q3-2008 of Winforms.
Thx,
JP

Edited theme not displaying as expected

Hello,

I have a rad panel bar which I want to display without the border.

So I set the theme to ControlDefault,
open the theme builder from the smart tag,
select RadPanelBarElement from the control structure tree,
edit the Bordercolor, BorderColor2,BorderColor3,BorderColor4 to all be transparent,
preview it and it look exactly as I want it to be.
Then I save the Style sheet in theme file (tried save theme as ... as well)
Return to project,
add the theme to the project,
Go to my RadThemeManage and Load Theme from resources,
Select the theme in the control properties and save.

Now run the prject and, as well as the borders being missing, the panel bar group elements are not as high and have changed colour...

Any ideas?

Hey all,

I'm having a really strange problem. I created a user control with a group box on it. I placed a few controls inside the group box, docked the group box to the user control, and anchored the controls in the group box to size accordingly. The problem I'm running into is that during the development of the control, everything looks and acts fine. After I compile and drop the user control onto a form, It creates a padded area to the right of the controls... Any ideas whats going on here?

I've attached a couple of screen shots of this for reference.

Databinding Drop down list based on another dropdown list

Hi guys,
I am getting this strange error and I am really pulling my hair at the moment. My scenario is simple. I have a drop down list for Categories. When the user Selects and category, I populate another drop down list of subcategory based on the selected category.
Here is the code

private void ddlCategory_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)

{

this.PopulateSubCategories();

}

private void PopulateSubCategories()

{

DataTable dtSubCategories = new SubCategory().GetSubCategoryByCategoryID(Convert.ToInt64(ddlCategory.SelectedItem.Value));

DataRow dr = dtSubCategories.NewRow();

dr["ID"] = 0;

dr["Name"] = "Any";

dr["CategoryID"] = 0;

dr["isACtive"] = true;

dtSubCategories.Rows.InsertAt(dr, 0);

this.ddlSubCategory.DataSource = dtSubCategories;

this.ddlSubCategory.DisplayMember = "Name";

this.ddlSubCategory.ValueMember = "ID";

this.ddlSubCategory.SelectedIndex = 0;

}

The problem is that ddlCategory.SelectedItem.Value statement throws exception, Unable to cast object of type 'System.Data.DataRowView' to type 'System.IConvertible'. If i skip this function first time and change the index to some other than it works fine. Why is it not returning the SelectedValue on first bind
Thanks

Grid view without horizontal scroll bar problem

Hello,

I encounter very strange problem while using the Telerik GridView.
I am creating the gridview on the fly & then populating the data in those gridviews.

Bydefault I am showing one row in each gridview as selected through programming.
The grid which contains the horizontal scroll bar & when I am looking at the source code of that grid, I am getting the following value which I am using in my jquery to findout the selected index of that specific grid from the 'value' attribute.

<input name="rg_02635_ClientState" id="rg_02635_ClientState" type="hidden"

autocomplete="off"

value="{"

selectedIndexes":["33"],"reorderedColumns":[],"expandedItems":[],"expandedGroupItems":[],"expandedFilterItems":[],"deletedItems":[],"scrolledPosition":"768,0","popUpLocations":{},"draggedItemsIndexes":[]}"/><

BR><BR>

But for the grid which doesn't contain the horizontal scroll bar & when I am looking at the source code of that grid, I am getting the following value, even if I have selected row in the grid.

<input name="rg_02637_ClientState" id="rg_02637_ClientState" type="hidden"

autocomplete="off"/><BR>

Strange thing is, if I select the highlighted row one more time manually, then I am able to see the following value.

<input name="rg_02637_ClientState" id="rg_02637_ClientState" type="hidden"

autocomplete="off"

value="{"

selectedIndexes":["0"],"reorderedColumns":[],"expandedItems":[],"expandedGroupItems":[],"expandedFilterItems":[],"deletedItems":[],"scrolledPosition":"0,0","popUpLocations":{},"draggedItemsIndexes":[]}"/><

BR>

Why is this strage behaviour? How do I get the selectedIndex for the grid which doesn't contain horizontal scroll.

Looking forward to your response.

Best Regards,
Vishal

What event fires on multiselect ?

I have a listcontrol set to MultiExtended. When the user clicks on an item the SelectedIndexChanged event fires. However, if the user holds the shift key down and clicks another item, selecting all items between clicks, the event does not fire. I need to know that the user just added items to the SelectedItems list. What event can I use? Thanks

Later
