How do I find RadGrid on ItemCommand Event of RadGrid that lies inside RadTreeList

Hi Telerik,

I have RadGrid inside FormTemplate of RadTreeList. I have called an "ItemCommand" event on RadGrid that bascially deleted the uploaded files when user clicks the delete button within ItemTemplate of RadGrid. All its happening is good. But as soon as deletion gets done I'm trying to rebind the RadGrid , but its giving me EXCEPTION.

RadGrid element is null.

Can you help me ?

Below is my code:-

protected void FilesRadGrid_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

{

foreach (TreeListDataItem item in KnowledgeBaseRadTreeList.Items)

{

RadGrid FilesRadGrid = item.FindControl("FilesRadGrid") as RadGrid;

if (e.CommandName == "Del")

{

string[] values = e.CommandArgument.ToString().Split(':'); // ID:FilePath

if (System.IO.File.Exists(Server.MapPath(values[1])))

{

try

{

System.IO.File.Delete(Server.MapPath(values[1]));

}

catch { }

}

Glb_Entities.ExecuteSP(new object[] { "Usp_KnowledgeBase_Uploads_Delete"

, "@KnowledgeBase_Uploads_ID", values[0]

});

FilesRadGrid.DataBind();

}

While my RadGrid lies in Form Template of RadTreeList as :-

<EditFormSettings EditFormType="Template" PopUpSettings-Width="100%">

<FormTemplate>

Telerik:telerik:GridTemplateColumn

We have a RadGrid with some telerik:GridTemplateColumns. We get a datasource and bind the grid. For first page grid behavour is consistent. But after page change, other columns in grid gets new values but itemtemplate columns persist the values from first page.

Grid Design Code :

<

telerik:RadGrid ID="rgvTest" runat="server" AllowFilteringByColumn="false"

AllowPaging="True" AllowSorting="True" MasterTableView-ShowHeadersWhenNoRecords="false"

AllowCustomPaging="false" AutoGenerateDeleteColumn="false" AllowMultiRowSelection="true"

AutoGenerateEditColumn="false" GridLines="None" ShowGroupPanel="True" OnItemDataBound="rgvTest_ItemDataBound"

OnPageIndexChanged="rgvTest_PageIndexChanged" OnSortCommand="rgvTest_SortCommand"

ClientSettings-ClientEvents-OnRowDblClick="GridRowDoubleclick" >

<

Columns>

<telerik:GridTemplateColumn HeaderImageUrl="../Images/priority_icon.png" UniqueName="Priority1"

HeaderTooltip="Priority">

<asp:Image ID="PriorityImage" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>
</Column>

Considering page size is set to 10.
After debugging , i got that OnItemdataBound event is called for first 10 records on load.
And after page change, it is called for 20 times but insted for 20 record of first page and second page, it is called twice for first 10 records... Strange but true.
If anyone has any idea abot this please help me out.

There is a problem with the editor and using MS Internet Explorer (any Version) by converting selected text into a bullet list.

What i'm doing:

Write three lines:

Select the three lines and press the button "Bullet List".

I'm trying to work with this which is more or less what i am looking for : http://demos.telerik.com/aspnet-ajax/grid/examples/programming/pivot/defaultcs.aspx

the problem the Row/Column headers are not the column names from my table. I need to write them directly in the code.
Some help would be welcome! thanks in advance

Line Series with figure

I have an line series and this series I own figures in circles. This series is powered by an array of double. Two things I'm not getting done.

1) I can not do it no plot, when the value of the array at that position is zero (0).

2) That it is series with the X axis, that is, zero. Within the circles I put a few labels. I wish to make circles stay in the middle of the line (series), as it is along the X axis, should come half circles at the top (positive) and half the bottom (negative). It has to do this?
