Hello,

I'm using the custom http handler method for AsyncUpload and I need to pass some values to my .ashx handler with query string. When I upload a 2048KB or smaller file everything works fine. But if I try to upload anything more than 2048KB, all query string variables become NULL but the UploadedFile content is fine. My application is setup to upload 2GB file and I have no problem with the standard method. What can possible cause the query string variables to become NULL?

Thanks.

</telerik:RadAsyncUpload>



<script type="text/javascript">

	function OnFileUploading(sender, args) {

		var obj = { CustomerID: window.CustomerID };

                args.set_queryStringParams(obj);

	}

	.....

</script>


protected

override IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration configuration, string tempFileName)

{

try

{

var CustomerID = context.Request.QueryString["CustomerID"

];

Align DropDown to right

Hi, Im using the RadAutoCompleteBox on the right side of my page and when DropdDown appears, it is aligned with the left side of the textbox with width expanding to the right (and I miss some portion of the DropDown content if too wide). Is there a way to align the DropDown to the right of the input textbox and have the its width growing to the left? Im not sure if the DropDownPosition property is for that since it doesnt seem to be documented in control's documentation.

TIA

Martin

Difference between client scripting usages

Hello all,
While handling controls in client side, some times I have to use $find("<%= txtSearch.ClientID %>") and some times $find("txtSearch").
So what is the difference between $find("<%= txtSearch.ClientID %>") and $find("txtSearch"). Also when I have to use $find("<%= txtSearch.ClientID %>") and $find("txtSearch"). Expecting a good explanation.

Thank you
Abhilash

RadUpload looks strange in IE 8

I just updated to the latest telerik ajax controls (2011.2 915) and now the RadUpload control looks very strange in IE 8. No matter what skin I put on it, it just looks like a gray box with a top and right border and no browse button.

In Firefox it looks correct.

Any ideas?

[Solved] Remove columns between Excel & CSV Export

I return data to a RadGrid and would like to give the user the option to either export it to a CSV and/or Excel file. The CSV file would only provide them limited fields that they would need in order to import it into another application. The Excel version would contain all the columns displayed in the Grid.

I am currently able to give them the Excel file but is this possible to give them the CSV file using the same grid results only exporting preselected columns? If so, how would I go about doing this?

Also, is it possible to display the filters (using radFilter) that were applied on the exported file?

Hierarchy Grid - Sorting & Paging

I have a "Main" grid on the page which generates many reports based upon the user selection.

Here is the code of the Grid:

<telerik:RadGrid ID="gvMainControl" runat="server" AutoGenerateColumns="true" GridLines="None"

CellPadding="0" CellSpacing="0" AllowPaging="False" Skin="WebBlue" AllowSorting="true"

ShowFooter="True" EnableLinqExpressions="false" AllowCustomPaging="false" >

<MasterTableView TableLayout="Auto" AllowFilteringByColumn="False" PageSize="20"

CommandItemDisplay="Top" AllowCustomPaging="false" >

</MasterTableView>

</telerik:RadGrid>

Some of the reports requires Hierarchy Grids within the MasterTableView which we create once the user clicks the "Generate Report Button". Here is the code to add the DetailsTables on Button Click:

For i = 0 To intLevels

Dim tableViewOrders As New Telerik.Web.UI.GridTableView()

tableViewOrders.DataMember = dicTemp(i).GroupBy.GroupBy(0)

gvMainControl.MasterTableView.DetailTables.Add(tableViewOrders)

Next i

We use the NeedDataSource event to re-populate the main grid when needed:

Protected Sub gvMainControl_NeedDataSource(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles gvMainControl.NeedDataSource

gvMainControl.DataSource = reporting_service.Run(Of Reporting.Item_DrillDown)()

gvMainControl.MasterTableView.DataKeyNames = {"Category_Name"}

gvMainControl.MasterTableView.ClientDataKeyNames = {"Category_Name"}

End Sub

Expending the grids works well and the data is shown via DetailsTableDataBind:

Protected Sub gvMainControl_DetailTableDataBind(sender As Object, e As Telerik.Web.UI.GridDetailTableDataBindEventArgs) Handles gvMainControl.DetailTableDataBind

If e.DetailTableView.DataMember = "Item_Name" Then

Dim strCategory_Name As String = CType(e.DetailTableView.ParentItem, Telerik.Web.UI.GridDataItem).GetDataKeyValue("Category_Name")

e.DetailTableView.DataSource = New Reporting_Service.Query(Global.Reporting_Service.Query.Report_Type.Items, New Dictionary(Of String, String) From {{"Category_Name", strCategory_Name}}, _

Nothing, New Reporting_Service.Query.Group(New List(Of String)({"Item_Name"}), New List(Of String)({"Quantity", "Total_Price"})), New List(Of String)({"Quantity"}), True, Nothing, Me.strUniqueID).Run(Of Reporting.Item_DrillDown)()

End If

Problem starts when you try to Sort or Page in the inner Grids. It simply doesn't work. No event gets fired, not "NeedDataSource" or "DetailsTableDataBind".

Your help is appreciated.
