Hi,

the range slider moving in opposite direction, start drag should not move after end drag. 

if the range of start drag is 4 and range of end drag is 5, currently start drag is moving after 5. 

have to stop this, if the start drag and end drag value is equal then drag should not slide.

I have a RadPanelBar in an asp:Panel so that I can provide grouping functionality and GroupingText.  Perhaps my choice of panelbar was inappropriate in this case, but the number of Level 0 items will almost certainly be larger than the space I've allocated to the panel, so a scroll is required.  For example, I have about 100 categories of reports to choose from, and within each category there are anywhere from 1 to 20 report items.

I can restrict the size of the panelbar with CSS on the container panel, with overflow-x and -y set to auto.  When data populates the panelbar, a scrollbar displays outside of the panel during control rendering, but it quickly disappears.
 
After selecting a Level 0 RadPanelItem (category), the list of Level 1 items displays, and then the panelbar scrollbar displays!

The size of the content panel for the open category is much larger than the number of items.  I might have 8 items but the default provides room for about 25 level 1 items before the next level 0 category displays.  I set the ChildGroupHeight on level 0 category items to 100 but it doesn't seem to affect the size of the space allocated for groups of level 1 children.  I am not using ItemTemplates.

Looking at the source via IE Developer Toolbar, I can see why the groups are mis-sized. 

Look at the rpSlide height in line 6 and the rpGroup hight in line 7.  Those numbers are off the wall considering the whole panelbar is only 370 pixels high per the code above.

1) How can I fix those Height params?

2) Any idea what's up with the disappearing scrollbar?

Thanks!

Config is VS2005 / .NET2 / RadControls v2009.1.402.20 / IE7 / Planet Earth / Milky Way

Lost the scrollbar when using HeaderTemplate in Explorer and Firefox.

Works in Chrome...

Hi,

We're using your RadFileExplorer as imagepicker in our software and are trying to improve the performance of it.
Some users don't sort their images into subfolders but puts all of their images in the root folder, with results high performance drop when not using pager with more than 2000 images in one folder (especially with slow internet connections).

Without pager: 20 seconds until 2 minutes to load
With pager: 5 until 10 seconds to load

But still very slow, we're targeting to 2~3 seconds (maximal).

It seems the thumbnail mode don't caches the generated views because the performance difference between grid and thumbnail modes is very huge, after first load as well. The grid mode seems loads within 1,5 seconds which thumbnail mode takes 5 until 10 seconds.

How we can improve the performance of the FileExplorer with thumbnail mode?

Hi,

I have a RadGrid that opens inside of a RadWindow.  The user can re-order the rows by drag and drop, but if the grid is longer than the height of the RadWindow, it does not scroll.  Is there a way to scroll the RadWindow as the user is moving the item down the list?

We would like to set the width of columns in xlsx export from a RadGrid. I do this by using e.ExportStructure.Tables[0].Columns in the InfrastructureExporting event handler. If columns are declaratively set in the aspx file when this works fine.

If, however, the columns of the RadGrid are added by setting AutoGenerateColumns="true" or manually in Page_Load, then the Columns collection is empty. Why is this, and are there some other way to set the width of the columns in the xlsx file?

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" OnNeedDataSource="RadGrid1_NeedDataSource" OnInfrastructureExporting="RadGrid1_InfrastructureExporting">
   <ExportSettings Excel-Format="Xlsx" />
</telerik:RadGrid>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" />

.cs:

public class Person
{
   public string ID { get; set; }
   public string Name { get; set; }
   public DateTime? Date { get; set; }
}

protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
   RadGrid1.DataSource = new List<Person> {
     new Person { ID = "1", Name = "Adam", Date = new DateTime(1973, 4, 12) },
     new Person { ID = "2", Name = "Bertil", Date = null },
     new Person { ID = "3", Name = "Ceasar", Date = new DateTime(1973, 10, 27) },
   };
}

protected void Button1_Click(object sender, EventArgs e)
{
   RadGrid1.MasterTableView.ExportToExcel();
}

protected void RadGrid1_InfrastructureExporting(object sender, Telerik.Web.UI.GridInfrastructureExportingEventArgs e)
{
  e.ExportStructure.ColumnWidthUnit = Telerik.Web.UI.ExportInfrastructure.ExportUnitType.FormatDefault;

  // ERROR: The Columns collection is empty if the columns of radgrid are auto-generated or dynamically added in code behind
  foreach (var col in e.ExportStructure.Tables[0].Columns)
  {
    col.Width = 20;
  }
}
