var selectedRows = window["<%=RadGrid1.ClientID %>"].MasterTableView.SelectedRows[0];

window["<%= RadGrid1.ClientID %>"].AjaxRequest("<%= RadGrid1.UniqueID %>", "No|" + selectedRows.KeyValues["No"]);

<radG:RadGrid ID="RadGrid1" runat="server" AllowPaging="true" GridLines="None" Skin="Office2007" AllowSorting="false" EnableAJAX="true" AutoGenerateColumns="false">

<MasterTableView AutoGenerateColumns="False" DataKeyNames="No">

<Columns>

<radG:GridBoundColumn DataField="No" UniqueName="No" HeaderText="No"

string[] arr1 = eventArgument.Split(new char[] { '|' });

txtNo.Text = arr1[1].ToString();

}

textboxes which is outside of radgrid in server side coding.
Please find me the solution as soon as possible.
Note: im using classic radgrid.

AllowedFileExtensions break validation

Hi,

I was trying to set AllowedFileExtensions in RadAsyncUpload, but no matter how I set it, it doesn't work (all the extensions are available) AND, what's worse, it breaks file size valildation - I have the MaxFileSize set for something like 3MB, but as long as AllowedFileExtensions are set, the validation fails for a 2MB file, while it lets through a file that is 18kB.

I've seen a few threads where you suggest to disable Silverlight. I've done it. I've also disabled flash - no avail.

I've tried to set it in markup, in code, using a dot before the extension as well as without it. Nothing works.

My project is using telerik 2010_3_something, so I thought maybe it got fixed in some newer version. I set up a new project with telerik 2012_1_529 in a totally new project - no change.

I'll probably try to use a custom validator now, hope it works... But anyway please tell me if there is possible to make it work anyway.

[Solved] Pre ticking checkboxes on load

I have a list in a RadDropDown, that users can select multiple values from, these are then saved to a database in a comma separated string.

When I wish to edit the data I need the same checkboxes to be ticked.

My code is atttached, I'm getting the first value to tick, but on subseqent values the x is null and no further binding takes place. The value of the selectedItem matched the value of Usr from the array.

'populate the dropdown and pre select checkboxes

If Not IsDBNull(u_ds.Tables(0).Rows(0)("LinkedUsers")) Then

Dim arrLinkedUsers As Array = Split(u_ds.Tables(0).Rows(0)("LinkedUsers"), ",")

For Each Usr In arrLinkedUsers

ddlClinic.SelectedValue = Usr

Dim x As RadComboBoxItem = DirectCast(ddlClinic.SelectedItem, RadComboBoxItem)

If Not x Is Nothing Then

x.Checked = True

End If

Next Usr

End If

Multiple templates based on bound data

Hey Guys,

I've come up against a sticky one here. I'm trying to apply a dynamic (from UserControl) ItemTemplate to my RadListView.
I do this OnItemDataBound and it works great except for the fact the ItemTemplate seems to have already been set up and so I end up modifying the template ready for the next record and not the current one. So all templates are staggered out-of-sync by one record.
It seems there is no event to handle that lets me check my dataitem in time to set the current ItemTemplate. I;ve read a solution online regarding the vanilla .NET ListView where you create a custom version which exposes what is effectively a "OnItemCreating" event where you can query the underlying data item in time to set the ItemTemplate accordingly.

I guess my question is really, have I missed something in Telerik's ListView that will allow me to do this? And if not, can I extend the Telerik ListView in the manner of that example and create an event where I can carry out my desired operations?

Many thanks for any help - code snippets below.

<telerik:RadListView ID="rlvJobsListPage" runat="server" ItemPlaceholderID="phJobsList" DataSourceId="objJobList"

OnItemDataBound="rlvJobsListPage_ItemDataBound" AllowCustomPaging="true" AllowPaging="true" PageSize="20" AllowSorting="True">

<LayoutTemplate>

<div id="searchList">

<div id="phJobsList" runat="server"></div>

</div>

</LayoutTemplate>

<EmptyDataTemplate>

No records found

</EmptyDataTemplate>

<ItemTemplate>First item gets this default - not my dynamic template like the rest of them do</ItemTemplate>

</telerik:RadListView>

protected void rlvJobsListPage_ItemDataBound(object sender, Telerik.Web.UI.RadListViewItemEventArgs e)

{

// Set each bound item to status "Loaded"

if (e.Item is RadListViewDataItem)

{

RadListViewDataItem thisDataItem = (RadListViewDataItem)e.Item;

Job thisListing = (Job)thisDataItem.DataItem;

//Formulate the Template name and Render it!

rlvJobsListPage.ItemTemplate = Templating.Render_ITemplate(Globals.SectionIds.Jobs, thisListing.ListingTemplate, TemplateType.Summary,

this);

}

VERY strange looking Upload control

Hi,

I am trying to use the RadUpload control in my application, but I am getting some very strange results, and no matter what I do it doesn't seem to change it.
Please see the attached screen shot.
There are 2 edit controls swhowing per file, along with a Browse button AND a select button, as well as a dot to the left.
It is currently set to use the Office2010Blue skin, but seems to ignore this.
Markup for the upload control shown below

<div style="left: 0px; position:absolute; top: 60px; height: 230px; width: 320px;">

<telerik:RadUpload ID="Upload" runat="server" MaxFileInputsCount="3" EnableEmbeddedSkins="true"

ControlObjectsVisibility="RemoveButtons, AddButton" SkinID="Office2010Blue">

</telerik:RadUpload>

</div>

Has anyone any idea how I can get this to look right?
What I really want, is for each file to show a text box, select button and remove button in the correct skin.

Thank you

Paul

[Solved] Grid Column Resizing Tooltip

Hello,

I am have currently added the following piece of JavaScript to the Column Resizing Event of a RadGrid I am using:

function ColumnResizing(sender, args)

{

if (args.get_gridColumn()._columnResizer._currentWidth < 60)

{

args.set_cancel(true);

}

It works so far, but now I would also like the "tool tip", which appears during the resizing and displays the exact width of the column, to stop at 60px. Is it possible to access the tool tip and set it's text in the code above, and would that work out as intended?

Thanks in advance,
Robin
