I put an Ajax panel on my page but now downloads do not work, I know is cause of the response.write stream. I s there a way to get around this in the code behind of the itemCommand. The downloads are in a sub grid of my main grid so I cannot take it out of the ajax panel.

<DetailTables>

<telerik:GridTableView DataKeyNames="intUploadId" Name="SubGrid" Width="50%" TableLayout="Fixed" Font-Size="10" AutoGenerateColumns="False" SkinID="Web20">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="intWarrantyNumId" MasterKeyField="intWarrantyNumId" />

</ParentTableRelation>

<HeaderStyle Font-Bold="true" HorizontalAlign="Center" />

<ItemStyle HorizontalAlign="Center" />

<AlternatingItemStyle HorizontalAlign="Center" />

<Columns>

<telerik:GridTemplateColumn HeaderText="File">

<ItemTemplate>

<asp:LinkButton ID="lnkDelete" runat="server"

CommandArgument='<%# Bind("intUploadId")%>' CommandName="DeleteDoc" OnClientClick="return confirm('Are you sure you want to delete this attachment');">

<asp:Image ID="imgDelete" runat="server" ImageUrl="~/Images/Delete Circle Small.png" BorderStyle="None" />

</asp:LinkButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="File">

<ItemTemplate>

<asp:LinkButton ID="lnkFile" runat="server" Text='<%# Bind("strLocation")%>' CommandArgument='<%# Bind("strLocation")%>' CommandName="Download"></asp:LinkButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

If (e.CommandName = "Download") Then

Dim filename As String = e.CommandArgument.ToString

'Dim path As String = Server.MapPath("~/RMAUploads/" & filename)

Dim targetfolder As String = "\\" & ServerName & "\iPBR\Warranty\" & filename

Response.AddHeader("Content-disposition", "attachment; filename=" & filename)

Response.ContentType = "application/octet-stream"

Response.WriteFile(targetfolder)

Response.End()

End If

Detail Table Issue

Hello,

I have found a weird problem with detail tables. After assigning the correct datakeys to the tables I found that one of my detail tables was not working even though there was nothing wrong with the query nor the detail table structure.

After a bunch of trial and error I found that unless the datakey names are the same in the Master and Detail grids, detail grids will not query any data.

In my mind this is a bug as we can assign whatever datakey names we want in the DataKeys attribute. The grid should not be enforcing a foreign key naming constraint, while a lot of the time these will be the same some times they will not and in those cases the master/detail relationship within the RadGrid breaks and does not work properly.

Full disclosure, our Telerik version is so old no one knows what version it is and we don't have access to the source files anymore to find out. It is a good bet it is pre-2013.

RadioButtonList in RadGrid ItemCommand

Can a radiobuttonlist trigger a call to ItemCommand inside a RadGrid. Below, the button works, but the radiobuttonlist does not hit the event in code behind.

<telerik:GridTemplateColumn AllowFiltering="false" HeaderText="Approvals" UniqueName="Approvals">

ItemStyle HorizontalAlign="Left" Width="140" />

<HeaderStyle HorizontalAlign="Left" Width="140" />

<HeaderTemplate>

</HeaderTemplate>

<ItemTemplate>

<asp:RadioButtonList ID="rdoApprovals" runat="server" RepeatDirection="Horizontal"

CommandName="ApproveDeny">

<asp:ListItem Value="1">Approve</asp:ListItem>

<asp:ListItem Value="2">Deny</asp:ListItem>

</asp:RadioButtonList>

<asp:Button ID="btnTest" runat="server" Text="test" CommandName="test" />

Custom root node(s) DataFieldParentID (not null and not default value)

A root node is interpreted by RadTreeView as any node with a DataFieldParentID of null or empty default value.

I have a hierarchy which is cut from a larger hierarchy and as a result, the Parent value (a Guid in this case) of the nodes I want to root are set to specific values. As I am binding to an ObjectDataSource I simply overwrite the Parent Guid for the root nodes in my BL with Guid.Empty.

However it would be nice if there were some way to specify the root value to hook on to so this fudge would not be necessary.

One alternative I tried was to create a static node with a value of the specific root Guid I want to hook on to. However I found that even with AppendDataBoundItems enabled the bound data does not hook on to the single, static, root node.

Has anyone else shared my experience?

Thanks

Single Control & Drop Zone for File Upload and Directory Upload

I was looking at the demos and playing around with the upload control. It seems that its designed to either be File uploads or Directory uploads, not do both at the same time. It seems we would would have to have two buttons one to allow choosing files and one to allow choosing a directory. The same with drop locations we could have a custom zone that accepts files and we would have to have another custom zone that only accepts a directory.

Below are some scenarios to help explain. I would love to know if all of these scenarios are possible and if so how. If they all of them are not then I would like to know what the reasoning is behind this limitation.

Scenario One

The user click an "upload" button that they can choice either 1 or more files, or 1 or more directories and the control will handle uploading all of them

Scenario Two

The user drags some files to a drop location and it detects they are files and uploads

Scenario Three

The user drags one or more directories to the same drop location as above and it detects they are directories and uploads the files represented within

Rad Editor content is not coming in <p> tag for single line text

Rad Editor content is not coming in <p> tag for single line text.

In Current Version 2018.2.710.45

While I put single line text like "Test" in rad editor and getting value in debug mode as "Test"

In Previous Version 2013.2.717.45
While I put single line text like "Test" in rad editor and getting value in debug mode as "<p>Test</p>"

My expected result is "<p>Test</p>" in this version 2018.2.710.45;

This is happening only for single line text .

Please give any solution.

Disable tooltip on client side events?

Hi,

I need to disable the tooltip on an appointment when I drop a row on top of it. Currently, if I do this, and remain atop the appointment (my cursor that is), it will bring up the tooltip and cancel my row drop if the background execution takes too long (which it does because this is a very busy calendar).

It would also help to disable it temporarily after a context menu selection.

Any help would be appreciated.

Thanks!

RadPanelItem ItemTemplate Not Binding

I am working with RadPanelBar and RadPanelItem objects. On page load, I have anIEnumberable of a type that I iterate over to build my 1st and 2nd layers of PanelItems. Iam using the ItemTemplate features and setting those to each object. The issue I'm encountering is that when I postback to update some information, The ItemTemplate for each PanelItem and it's children is null. Below is a snippet of how i'm building out the PanelBar. I need to be able to access the user controls inside each template to update some data.

foreach (var integration in integrations)

{

RadPanelItem integrationGroup = new RadPanelItem(integration.Name);

integrationGroup.ItemTemplate = new IntegrationItemEnabledTemplate(integration.UniqueId, integration.IsActive);

foreach (var param in integration.Parameters)

{

if (!string.IsNullOrEmpty(param.Key))

{

var pnlItem = new RadPanelItem();

pnlItem.ItemTemplate = new IntegrationItemTemplate(param.Integration, param.Key, param.Value);

integrationGroup.Items.Add(pnlItem);

}
