RadGrid show or hide filter on RadPanelBar click.

Hi I have a RadGrid that is inside of a UserControl, and is used inside of an aspx page that contains a RadPanelBar. When the user clicks the RadPanlBar buttons the gird is displayed. I have to use a filter on my grid, but I only want the filter to display if a certain RadPanelBar button is clicked. I have the following code in my RadPanlBar ItemClick event.

protected void CategoriesPanelBar_ItemClick(object sender, RadPanelBarEventArgs e)
{
e.Item.Selected = true;
if (e.Item.Expanded || e.Item.Items.Count == 0)
{
// This is a leaf we select the parent and this child only
if (e.Item.Items.Count == 0)
{
createDiscountGridControl.SelectedParentCategory = ((RadPanelItem)e.Item.Parent).Value;
createDiscountGridControl.SelectedCategory = e.Item.Value;
}
else
{
createDiscountGridControl.SelectedParentCategory = e.Item.Value;
createDiscountGridControl.SelectedCategory = null;
}
createDiscountGridControl.Rebind();
//createFilter(int.Parse(e.Item.Value));
if (e.Item.Value == "319")
{
Controls.DiscountGrid userControl = createDiscountGridControl;

var rg = ((RadGrid)userControl.FindControl("RadGridDiscounts"));

GridColumn column = rg.MasterTableView.GetColumnSafe("ProductName");
column.CurrentFilterFunction = GridKnownFunction.Contains;
column.CurrentFilterValue = "Product_Name";
rg.AllowFilteringByColumn = true;

rg.MasterTableView.Rebind();

}
}
}

This line is the button that when clicked should show the grid.

if (e.Item.Value == "319")

I'm getting a null reference exception on the line

GridColumn column = rg.MasterTableView.GetColumnSafe("ProductName");

column is coming back null. It's like it can't find the column inside of the Grid. Here is the code for my RadGrid UserControl. The column in question has a unique name of ProductName.

Issue on RealFontSizes .unable to get pt in the dropdown of font size

Hi Team,

Good evening.

We are using RAD Editor of Telerik .We are facing some issue on “RealFontSizes” tag while retrieving font size dropdown .
Below is the code which we are using to get the size in “pt”

<RealFontSizes>
 <telerik:EditorRealFontSize Value="12pt" />
 <telerik:EditorRealFontSize Value="26pt" />
 <telerik:EditorRealFontSize Value="36pt" />
</RealFontSizes>

But we are facing below issue while running in IE browser :

When we are selecting any size from dropdown ,its coming as in “ pt” as shown in the attached "radeditior_fnt_pt_ select.png" file.
 But when we select any size eg. (26pt as above) it is displaying it as in “pixel “ after the selection as shown in the attached "radeditior_fnt_px_dsply" file.

It will be if you can provide any solution on this ,so that if I will select “26pt” it should show me “26 pt”.

Thanks and Regards,
Swetalana

Table Header and Page Breaks with Print Media Query

I am using CSS print media query to modify page layout when printing and I am unable to set the following. All other styles are working properly.

@media print{

thead{display:table-header-group;}

tr{page-break-inside:avoid;}

}

The following post is quite old, but should still work, however it doesn't. All I see where I expect to see the header on each page is a small black border box just under the first column header on each page as seen in the attached files.

http://www.telerik.com/support/code-library/printing-grid-headers-on-every-page

Page breaks also aren't working to prevent rows from being cutoff. The grid spans multiple pages and rows should not be cutoff between pages.

Any suggestions are greatly appreciated.

RadPanelItem Heightis not Reflected

I have two RadPanelItems in a RadPanelBar.

The First RadPanelItem has list of Controls and it goes up to 20 lines of controls. But when it is viewed in the browser all the 20 lines of controls are not visible due to the height which is set as AUTO is not reflected. Vertical scroll bar is shown to view the all the lines. I don't want to have the scroll bar, Instead i need to show all the lines of code at a single page.

[Solved] Get parent item from grid inside a nestedviewtemplate

Hello,

I have a datagrid1 which contains another datagrid2 inside a nestedviewtemplate. With datagrid2 I insert, update and delete records with the help of the different command events.

How is it possible to get the parent item inside the OnItemCommandEvent, if I click on "Add new record" or on the button inside my GridEditCommandColumn. I tried e.Item.OwnerTableView.ParentItem inside the OnItemCommand-event, but the ParentItem is always null. Thanks in advance.

Kind regards,
Felix
