Multiple image editors and open dialog OnClientLoad

Hi There,

I have multiple image editors loaded on a page. All have a OnClientLoad function which does a executeCommand('crop').
The dialogs are opened, but only the last image editor is showing the crop dialog. The other dialogs seem to be hanging and can't be opened/closed anymore.

Many thanks in advance for your support!

Grouping bug in build 1002

Hi,

I found an other problem in the grid. If you have two columns bound to the same datafield grouping will fail with the following error:
An item with the same key has already been added

Example:

<telerik:RadGrid ClientSettings-AllowDragToGroup="true" ShowGroupPanel="true" ShowFooter="true" runat="server" ID="rg" AutoGenerateColumns="False" GroupPanelPosition="Top">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn HeaderText="id" DataField="id"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="value 1" DataField="Value" UniqueName="Value1"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="value 2" DataField="Value" UniqueName="Value2"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Code behind:

Protected Sub rg_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles rg.NeedDataSource

If e.IsFromDetailTable = False Then

Dim dt As New DataTable()

dt.Columns.Add("id", GetType(Integer))

dt.Columns.Add("text", GetType(String))

dt.Columns.Add("value", GetType(Double))

Dim r As DataRow

r = dt.NewRow()

r("id") = "1"

r("text") = "nr. 1"

r("value") = 1.5

dt.Rows.Add(r)

r = dt.NewRow()

r("id") = "2"

r("text") = "nr. 2"

r("value") = 2.5

dt.Rows.Add(r)

rg.DataSource = dt

End If

End Sub

RadComboBox in Radgrid template column giving issues when changing index

I have a Radgrid with a RadComboBox in a templateColumn. My other columns are AutoGenerated. By default the template column comes as the first column in the grid. If I leave it like that, it will work just fine. But whenever I change the index of it (and it actually moves), the RadComboBox in the first 9 rows stops working. From row 10 until the last it works again. I also tried with Autogenerate= false. Same issue.The code is use to change the index is in the aspx.cs file, gets called on PreRender Event and looks like this:

GridColumn c = RadGrid1.MasterTableView.GetColumnSafe("Temp");
if (c != null)
{
int total = RadGrid1.MasterTableView.RenderColumns.Count() - 2;
for (int i = total; i >= 2; i--)
{
RadGrid1.MasterTableView.RenderColumns[i + 1].OrderIndex = i - 1;
}
c.OrderIndex = total + 1;
}
RadGrid1.MasterTableView.Rebind();

Identifying the selected image server side

I am displaying a number of images in thumbnail area with DisplayAreaMode="ToolTip".

Then a user clicks an image, it selects the thumbnail and shows the tooltip with a larger image. Works great!

When the tool tip goes away, the thumbnail is still selected -- how would I get the selected Thumbnail on the server side?

Thanks,
Todd.

hide link in status bar from GridHyperLinkColumn

Does somebody know how to hide the link from GridHyperLinkColumn.DataNavigateUrlFormatString ?
I mean not showing in the browser status bar.

In asp.net for Hyperlink control there is a OnMouseOver javascript event very useful to do this.

Thanks in advance.
