Hi,

I am looking for a way to keep the edit buttons fixed somewhere in the RadTreeList. The treelist will be scrolling horizontally, but I'd like to find a home for the buttons where they will always be visible to the user, or at least be consistent across rows. Is there a way to achieve this?

I was thinking something like "fixed" columns? Failing that, if they could be the first two columns, but without the indentation, similar to the WPF control's Hierarchy Column (http://www.telerik.com/help/wpf/radtreelistview-features-hierarchy-column.html)?

Appreciate your help.

I am trying out the new multicolumn headers feature in version 2012.2.607.35 and have a couple of issues:

Using the ColumnGroups Collection editor on the property page for the grid and as soon as I click on the Add button I get the error message:

Group name cannot be null or empty string.
Parameter name: Name

Which is empty because I just clicked on the Add button!

Then I enter the Name for the GridColumnGroup which I am using "ContactDetails" and then click on the OK button and in design mode the display of the grid crashes and displays:

RadGrid - RadGrid1System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: index at System.Web.UI.ControlCollection.get_Item(Int32 index) at System.Web.UI.WebControls.TableCellCollection.get_Item(Int32 index) at Telerik.Web.UI.GridHeaderItem.get_Item(String columnUniqueName) at Telerik.Web.Design.RadGridDesigner.Grid_ItemDataBound(Object sender, GridItemEventArgs e) at Telerik.Web.UI.RadGrid.OnItemDataBound(GridItemEventArgs e) at Telerik.Web.UI.GridItem.SetupItem(Boolean dataBind, Object dataItem, GridColumn[] columns, ControlCollection rows) at Telerik.Web.UI.GridTableView.CreateMultiColumnHeaders(Boolean useDataSource, GridColumn[] copiedColumnSet, GridTHead thead) at Telerik.Web.UI.GridTableView.CreateControlHierarchy(Boolean useDataSource) at Telerik.Web.UI.GridTableView.CreateChildControls(IEnumerable dataSource, Boolean useDataSource) at System.Web.UI.WebControls.CompositeDataBoundControl.PerformDataBinding(IEnumerable data) at System.Web.UI.WebControls.DataBoundControl.OnDataSourceViewSelectCallback(IEnumerable data) at System.Web.UI.DataSourceView.Select(DataSourceSelectArguments arguments, DataSourceViewSelectCallback callback) at System.Web.UI.WebControls.DataBoundControl.PerformSelect() at Telerik.Web.UI.GridTableView.PerformSelect() at Telerik.Web.UI.GridTableView.DataBind() at Telerik.Web.UI.RadGrid.DataBind() at System.Web.UI.Design.WebControls.DataBoundControlDesigner.DataBind(BaseDataBoundControl dataBoundControl) at Telerik.Web.Design.RadGridDesigner.DataBind(BaseDataBoundControl dataBoundControl) at System.Web.UI.Design.WebControls.BaseDataBoundControlDesigner.GetDesignTimeHtml()

I have a question about functionality of this control.

Here is my scenario: I have an ASPX page with a RadWindow that has a ContentTemplate that appears from clicking a button. Nothing complicated, the button just does this

OnClientClick="openUploadWindow1(); return false;

Inside of the RadWindow that opens I have (among other controls) a RadAsyncUpload control that automatically uploads a file to the default temporary directoy and a DIV that contains the image of a file that is saved to a database. What I'm trying to do is the following:

Someone uploads a TIFF image through the RadAsyncUpload tool. I would like to display this image in the aforementioned DIV as soon as the image is finished uploading to the temporary directory. However, TIFFs can't be viewed normally in a browser, so I would need to post-back to the server to convert it to a JPG, PNG, or BMP and then display that image. However, I don't see a method that handles this scenario.

In brief I want to:
  • Open a RadWindow
  • Select a file that is immediately uploaded via RadAsyncUpload in that RadWindow
  • As soon as it's finished, call some server-side function or at least post-back to the server
  • Convert the image to a JPG
  • Re-open the dialog box with the controls on my RadWindow with the same information

This since it's posting back it sounds like more a job for RadUpload, but there's most likely functionality in RadAsyncUpload that I don't know about.

Thank you for your time.

 I have been trying to get grouping int the grid to rebind through many, many different routes.  I have used hidden fields, ViewData, postback, grid actions and though the data will reapply there doesn't appear to be any way to get the grid to reevaluate the grouping. 

Why must we use the drag/drop to get groups to update?  Is there any way to do it programmatically?  How do I assign the group by variable?  It seems to send a string similar to filter (e.g. "Filter1-asc~Filter2-asc") but there is no way to force the grid to use the grouping you wish to assign?

I look at this example (http://demos.telerik.com/aspnet-mvc/Grid/Grouping) and it is no help.  I did exactly what is in there (minus the
"Configurator").

I am starting to the think the "Configurator" rewrites the HTML so that the entire page is recompiled and therefore the grouping is reevaluated.  I've seen that it is supposedly irrelevant but I have done everything but that and the grouping does not take.

Has anyone had success that can help me?

******* UPDATE - Just as I had given up I came across the answer.  I had a case of making it more complicated than it needed to be.  I set the grid "groupBy" variable and it worked.

Hello!

I've implemented the RadTreeView successfully in a RadPane, within a RadSplitter.
But now the formatting of the TreeView is very malformed, it looks like each TreeNodeItem is beeing centered. Does anybody know a reason where this can come from?

Here is a sample code and attached the sample outputs:

<div style="width:700px; height:300px;">
          <rad:RadTreeView ID="TestTree" runat="server" Height="200px" Skin="Windows7" BorderWidth="3" style="float: left">
                <Nodes>
                    <rad:RadTreeNode Text="Test1" Expanded="true" runat="server">
                        <Nodes>
                            <rad:RadTreeNode Text="Test2" runat="server">
                                <Nodes>
                                    <rad:RadTreeNode Text="Testasdfjklö2" runat="server" >
                                    </rad:RadTreeNode>
                                </Nodes>
                            </rad:RadTreeNode>
                            <rad:RadTreeNode Text="Test3" runat="server" >
                                <Nodes>
                                    <rad:RadTreeNode Text="Testasfwqeradfawererdfgrthrtzh3" runat="server" style="float: left">
                                    </rad:RadTreeNode>
                                </Nodes>
                            </rad:RadTreeNode>
                        </Nodes>
                    </rad:RadTreeNode>
                </Nodes>
            </rad:RadTreeView>
        </div>


Thank you very much for every help!

Kind regards

While it would be really nice to be able to have a built in multi file download, what about downloading a single file with drag and drop to the desktop as shown here:
http://www.html5rocks.com/en/tutorials/casestudies/box_dnd_download/

If we could do something like this in most cases it would not be a problem for the user to need a multi file download.  Is the drag and drop download possible with this control?  Do you have any information on how to accomplish it?

Thanks,
Ryan

Just recently updated our application with the latest Telerik release for IE10 support.  Majority of the bugs we saw are now resolved.  However, we are noticing an issue with the RadMenu.  On the expand of drop down menu, an iframe is rendered behind the menu item and can be seen with an "Windows Internet Explorer cannot load this page" or something along those lines.  Basically you can see the IE "World" image loaded behind the menu and once the menu is expanded it is covered up.  It is brief but noticeable.  

Do you have any suggestions or workarounds?  I do see the iframe markup so was considering adding a .rmSlide iframe CSS styling to perhaps hide it.

I tried to grab a screenshot but its near impossible to time it right.

Hi everyone,

now I am making my database model and I would like to know if telerik needs to have primary keys in coupling tables?

I hope you understand my "coupling tables".

Thank you for your replies.

I have a user control inside of a rad grid.
When you expand the radgrid row for edit or insert I have a listbox that displays a set of items in a source and a destination box where the items they transfer are...
I would like to validate that the destination box has at least one item either via a asp.net validation control or via client side javascript.
The issue with the clientside script is that I am having a hard time getting it to work since it is a USER CONTROL inside of a parent page..

Any ideas?
