Hi

Please help urgently!

I have been working on a project for many months, the site is live and working fine.
I booted up this morning and tried to add a Telerik control to a page in Visual Studio. 
In design view, nothing happens, in source view, I get the dreaded 'Operation could
not be completed'.

I tried the advice already in the forums, but no solution so far. Work has come to a grinding
halt with Telerik controls.

As a test I then created a new web site using the RadControls template.
When I try to add controls to the default page, I get the same error, so it is not project
dependent apparently.

I guess this may be a vidual studio problem but can anyone tell me how to fix it?
This is not a new installation! Worked fine until today.
Setup is Windows vista ultimate, IIS7, Q2 2009 RadControls, VS 2008.

Please help!

Thanks
Clive

hi there,
i'm having a trouble in radtreeview, and i'm so confused about it.
i'm using radtreeview to load data from SQL DB, and checkbox involves.
i have three level of employee (it mean i have 3 level of nodes)  and i display all employees on my radtreeview,
i want to click to checkboxes to select employees id, then insert into my DB.
but, when i click to my employees's level 3, ( it mean : this node at 3th level )
i can not refer to parent of this node ( refer to manager of this employee ) to select  value of node.
can you help me to resolve this proplem.
thanks,
ps: best regards.
this is my code :
AspTree.aspx

div class="center" style="width:500px; height:auto; float:left;">

<radt:radtreeview id="RadTreeView1" runat="server" CheckBoxes="True"

 

 

OnNodeClick="NodeClick"

 

 

OnNodeCheck="RadTreeView1_NodeCheck" AfterClientCheck="AfterCheck"

 

 

 

></radt:radtreeview>

parentNode = node.Parent;

 

 

string PNode = parentNode.Value;

if (RadTreeView1.Nodes.FindNodeByValue(PNode).Checked)

 

{
    // do something if parent node checked.

I have two radgrids on the same page being populated with data. On each grid I have this setting: 
PagerStyle-Position="Bottom"
However, on postbacks it seems that the pager display will appear on the top and bottom of both grids. I don't set this anywhere else in the code. What would cause the property to reset? How can I get it to maintain its value? I can post any code that is needed. Thanks.
 

Radsplitter will not take up even half the  height of page.   It is stuck at 400px in height, width is not affected.  I can make it smaller but not bigger.  I would like it ideally to fill 90% of the page.  The splitter has two panes, radlist in one pane and radeditor in the other.  Would like 90% of page width covered by rad splitter, and would like it to stay at that percentage even if the browser dimensions change.

Tried the splitter.resize(x,y) in client side script; again I can't get height over 400px, although I can make it smaller. 

Thank you all in advanced.

Attached is screen shot, and below is aspx file;

My application currently has a RadGrid that is connected to a database with additional two GridButtonColumns.  Both of the buttons have 'Delete' commandNames so they both access the same class when the delete command bubbles.  I wanted them to access seperate classes based on which button they will click. 
Does anyone have any ideas I am currently stuck.
Thank you!

Hi,
I am using 2009.3.1314.20. When i filter for  only "%" character with "contains" filter function, filter do not works (It do not throw any error). But when use any other character with "%" like "10 %" it's showing me correct records. I do not want to change version. Anybody solved this issue, Please let me know.

Thanks,
Yogesh

I have a hierarchical RadGrid that is editable.  If you edit a row that is expanded, the row collapses once in edit mode.  Once its in edit mode, you can expand it again and it remains in edit mode. This can be seen in the Telerik demos (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/threelevel/defaultcs.aspx) so I'm guessing this is the way it was designed, and is not a bug.  But is there a way I can prevent a row from collapsing when it enters edit mode?

Thanks,
Justin

Hi,

why following code is not changing the header background color?
<HeaderStyle Font-Bold="true" BackColor="#FF9900"/>

Many thanks

My requirement is to open a Detail Table in a Hierachy RadGrid from a double click.  We have the expand arrow working fine for this, but would also like to have Row Double click do the same thing. 

Here is sample of what we currently have:

Designer:

<telerik:RadGrid ID="rgvOrderHistory"
                 runat="server"
                 AllowPaging="True"
                 AllowCustomPaging="true"
                 AllowSorting="true"
                 AutoGenerateColumns="false"
                 AllowFilteringByColumn="false"
                 OnSortCommand="rgvOrderHistory_SortCommand"
                 OnNeedDataSource="rgvOrderHistory_NeedDataSource"
                 OnItemDataBound="rgvOrderHistory_ItemDataBound"
                 OnDetailTableDataBind="rgvOrderHistory_DetailTableDataBind"
                 CssClass="rgvOrderHistory"
            onitemcommand="rgvOrderHistory_ItemCommand" >
    <MasterTableView DataKeyNames="OrderNumber"
                     AllowPaging="true"
                     PageSize="10"
                     PagerStyle-AlwaysVisible="true"
                     PagerStyle-Mode="NextPrevAndNumeric"
                     AutoGenerateColumns="false"
                     AllowFilteringByColumn="false"
                     Name="OrderHistoryMaster">                              
            <Columns>
                 //SOME BOUND COLUMNS
   </Columns>
                
                     <DetailTables>
                        <telerik:GridTableView AutoGenerateColumns="false"
                                               AllowPaging="false"
                                               AllowFilteringByColumn="false"
                                               CssClass="rgvOrderHistoryDetails"
                                               Name="OrderHistoryDetail"
                                               DataKeyNames="ProductID" >
                       <Columns>
                            //SOME BOUND COLUMNS
  </Columns>
</MasterTableView>
   <ClientSettings></ClientSettings>
</telerik:RadGrid>

Code Behind:

   protected void rgvOrderHistory_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
        {
            try
            {

                if (e.IsFromDetailTable) return;

                int virtualItemCount;
                rgvOrderHistory.DataSource = GetOrderHistoryDataSource(out virtualItemCount);
                rgvOrderHistory.VirtualItemCount = virtualItemCount;
            }         
            catch (Exception ex)
            {
                //some code
            }
        }

  protected void rgvOrderHistory_DetailTableDataBind(object source, GridDetailTableDataBindEventArgs e)
        {
            try
            {

                GridDataItem dataItem = e.DetailTableView.ParentItem;
                int orderNumber = (int) dataItem.GetDataKeyValue("OrderNumber");
                int virtualItemCount;

                e.DetailTableView.DataSource = GetOrderHistoryDetailDataSource(orderNumber, e.DetailTableView.PageSize,
                                                                               e.DetailTableView.CurrentPageIndex,
                                                                               out virtualItemCount);
                e.DetailTableView.VirtualItemCount = virtualItemCount;

            }
            catch (Exception ex)
            {
                //some code
            }
        }
