Combobox empty despite binding datasource

So I've got a control that uses a radcombobox. Said control exists in two nearly identical pages, but on one of the pages it's empty. Doing a step through on the codebehind shows that the datasource is binding correctly and is populated with information.

So I'm left here scratching my head trying to figure out why the combobox on this one page is always empty. In both cases the combobox is in a separate table above a radgrid, and is loaded when the grid calls it's NeedDataSource function on postback (after search, the box is used to determine an action to take against an item in the list).

It looks as if everything is fine on the server side.

<telerik:RadComboBox id="actionbox1" Runat="server"

ToolTip="Select a Bill action" MarkFirstMatch="True" EnableLoadOnDemand="false" ShowDropDownOnTextboxClick="False" Width="176px">

</telerik:RadComboBox>

[Solved] how to refresh radgrid?

hi,

I have rad grid control and radcompobox, now whenever I change radcombobox index, the page is post back and RadGrid1_NeedDataSource will be fired again with different datasource (because when changing combobox index the sql statment is changed and datatable is changed too) and the grid should be changed, but the problem its remaining same as it is!!

when I click refresh button in radgrid, then content of grid changed!

so the question would be, how to refresh datagrid after assigning datasource to different table?

[Solved] Chart not rendered with AjaxLoadLoadingPanel on PageLoad

I want to use the RadChart component. To try it, I first used the Telerik demo for scrolling and zooming (http://demos.telerik.com/aspnet-ajax/chart/examples/newfeatures/zoomingscrolling/defaultcs.aspx) and it works.

But when I put this code in our application, the chart is not renderer properly after the first page load, no data is shown and the loading image still there. It happen if I show the loading panel on page load as described on Telerik on-line documentation (http://www.telerik.com/help/aspnet-ajax/ajax-show-loadingpanel-on-initial-pageload.html).

I tried to bind data again on ajax request without sucess as in this post (http://www.telerik.com/community/forums/aspnet-ajax/ajax/show-loading-panel-on-initial-page-load.aspx) except I remake the entire data source because the chart don`t have a Rebind() method.

Anybody have an idea about how to use the RadChart component and still having a loading panel on page load?

Thanks.

File Manager with CustomFileSystemProvider

We are using the File Explorer with a CustomFileSystemProvider. When a user uploads a file, there is a method to check if the user has access to the share the file is being uploaded to. The method is called CheckWritePermissions:

public override bool CheckWritePermissions(string virtualTargetPath)

The method signature only provides access to the path of the folder. However, we need to also access the filename that is being uploaded as well, to do an additional check to see if the file already exists. At present, there doesn't seem to be any way to do this.

Does anyone know of a way to modify the CustomFileSystemProvider to access the filename when a user uploads documents to a share? Since users can upload multiple documents at a time, the method should show the current filename that is being processed as the files are uploaded.

Getting grid editable row value in code behind on timer tick event

Hi All,

In our application we used telerik rad grid and timer control. Have a editable text box inside a grid. The timer interval is one min. In timer tick event I am saving grid data in to the session. There is around 500 lines in grid. There are two scenario .
1. Entered the value in editable text box of the grid. And check entered value from grid in code behind (in .cs file) am able to get all the values from the grid.
2. Entering the data in text box and continue till the end of the grid, meanwhile in the middle timer tick event fires then I am not getting all editable rows value in code behind of the grid.

Eg: Grid contains 300 rows to be entered. After inserting value in 200 rows timer tick fires and try to save the data of 200 rows.
But am able to get 130-150 rows of data in that timer tick event when try to read from grid data . In timer tick event i am using this code to read the grid value in code behind.

foreach (GridItem item in grid.Items)

{

RadNumericTextBox txtBox = (RadNumericTextBox)item.FindControl("txtBox");

}

Kindly someone help me to resolve this issue. Thanks in advance.

Pavan

[Solved] Cannot hide a control in GridTemplateColumn

Hi,

I have an issue hiding one of the controls in my grid. This is the GridTemplateColumn

<Telerik:GridTemplateColumn UniqueName="Results" DataField="Results" HeaderText="Results" AllowFiltering="false" >

                     <ItemTemplate>

                      <asp:LinkButton ID="Upload" runat="server" CommandName= "Edit"
                     Text="Upload" EnableViewState="true">
                     </asp:LinkButton>

                     <asp:LinkButton ID="Download" runat="server" CommandName= "Download" CommandArgument='<%# Eval("Results")%>' Text="Download" EnableViewState="true">
                     </asp:LinkButton>

                     </ItemTemplate>

                   <EditItemTemplate>

                      <telerik:RadUpload ID="ResultsUpload" runat="server" ControlObjectsVisibility="None" InputSize="55" />

                     </Telerik:GridTemplateColumn>

I am trying to hide the Download control depending on certain condition. Here's my vb.net code

Protected Sub Radgrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

        If TypeOf e.Item Is GridDataItem Then

            Dim eItem As GridDataItem = TryCast(e.Item, GridDataItem)
            Dim filename As String

            For Each item As GridDataItem In RadGrid1.MasterTableView.Items

                Dim Download As LinkButton = TryCast(eItem.FindControl("Download"), LinkButton)
                filename = Download.CommandArgument
                If (Download.CommandArgument = "Not Available" Or Download.CommandArgument = Nothing) Then
                    Download.Visible = False
                Else
                    Download.Visible = True
                End If

            Next
        End If
    End Sub
My problem is I am able to hide all the download linkbuttons except the first row. first row will always shows download button even if the condition is not met.

Any one has any idea about this issue please let me know. Thanks

Unable to collapse all groups in RadGrid

                            </telerik:GridBoundColumn>

                            <telerik:GridBoundColumn DataField="AskedForCount" HeaderText="Asked For invitations" Aggregate="Sum" FooterText="Total: ">         
                            </telerik:GridBoundColumn>         
                            <telerik:GridBoundColumn DataField="TotalCount" HeaderText="Total" Aggregate="Sum" FooterText="Grand total: ">         
                            </telerik:GridBoundColumn>         
                        </Columns>         
                    </MasterTableView>         
                </telerik:RadGrid>         

And I would like to have both levels of grouping collapsed by default. I've tried the following property on the MasterTableView:

                    GroupsDefaultExpanded="false"         

But this only seems to collapse the top grouping level. When you expand on of the top groups, all of its subgroups open up expanded!

So next, I tried the following in the OnLoad method, as instructed by http://www.telerik.com/help/aspnet-ajax/grdcollapseallitemsongrouping.html:

                    if (!IsPostBack)         
                        {         
                            uxByAgeAndGenderGrid.Rebind();         
                     
                            foreach (GridItem item in uxByAgeAndGenderGrid.MasterTableView.Controls[0].Controls)         
                            {         
                                if (item is GridGroupHeaderItem)         
                                {         
                                    item.Expanded = false;         
                                }         
                            }         
                        }         

But I get the following error:

                    Server Error in '/' Application.

Radgrid add new record data checking

In a Radgrid, how do I keep the add new record open when someone clicks the save button and I check to make sure the data is all in the correct format or valid? I want the add new record to stay open after I tell them the data is not valid and also keep the values they have already entered.
