I have a radgrid and I am populating the grid using data returned from a web service call (after massaging the data returned by WS) A lot of records are returned from this web service calls. I would like to paginate it ,but paginating in the server side makes another call to WS, which I do not want.

On top of it, during post backs the gridItemCount is set to the page size, though there are more records than the page size.

I would like to do some sort of pagination in the client side, where clicking on next/prev would just hide/show relevant pages. And when the page does a postback, I would like to "post" the entire grid instead of a portion of it. Is it possible ?

[Solved] RadGrid Upload in edit mode

Hello
I have a RadGrid with only one MasterTable.
The user can Update, Edit or Insert in this Grid.
When the user Edit a record, I would like to display a upload control to be able to upload the logo of the company and then save it to my table. Is it possible to have this as a gridbound column as I would like also that when the user click on Edit, it display the value that is already in the table..
Thanks in advance

And does it has a property where I could set the width of my controls in the edit part?
Thanks again

FilterExpression when Datasource and Excel Spreadsheet

Hello

We have a particular grid in our system where a user can say where the data comes from, they can choose a database or excel spreadsheet.

When the grid is bound they can choose which column they want to filter from a drop down and enter the filter in a textbox.

                     string filterExpression;         
             filterExpression = "(" + list.SelectedItem.Value + " Like '%" + txt.Text + "%'" + ")"; 
            
            Grid.MasterTableView.FilterExpression = filterExpression;
                    

The grid is then rebound as usual.

This all works well when they choose a database as their datasource, but when an excel spread sheet is used it does not work.

Should the filter work on excel datasources? or from my code extract above can you see an obvious reason why it would not work?

Thanks

static header (how?)

Is there any way to achieve a staic header within a RadWindow, so that I could put a menu or toolbar there that would not scroll with the page data?

Fixed width Appointments

I am working on a hack to allow for fixed width appointments, but i am having problems determining for a resource the max number of appointments that are side by side. So here is the way I am trying to get it to work.

I am using the ColumnWidth property set to 110 so i want each appointment to be approximently 100px. Now if I can determin the max number of appointments that are side by side for a resource, I can, with jquery i am planning on over writing the percentages in the header and content with fixed widths based on the max number of appointments.

This should allow the appointments to stay with a % and work as normal.

I have seen quite a bit of complaining on here about this so if you have a better solution please let me know.

Getting HTML formatting using ExcelML

I like the presentation capabilities of using ExcelML with export to excel.

However, I have a column that has html formatting ... when I use the ExcelML option, then just the code shows up.
If I use the HTML option, then is displays correctly but then I lose funcitionality of the ExcelML such as the sorting capabilities in the header cells.

Is there a way to get the HTML formatting to show in the ExcelML option?

thanks

Reporting Services Compatible with the RadGrid?

Hi support,

I am attempting to reproduce the nested view templates demo; seen here: http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx. However, I want to use Reporting Services 2005's report viewer control to show a report inside the NestedViewTemplate. My problem is the report is being pushed together and bunched up when inside the NestedViewTemplate area of the hierarchical grid. My question is: Is Reporting Services 2005's report viewer control compatible with the RadGrid and inparticular the NestedViewTemplate?

Thanks,
Josh

[Solved] RadGrid NestedViewTemplate/DetailTables and Web Service Data-Binding

Hello,

I've been playing around with RadGrid in a financial application that retrieves its data every second. In order to reduce server load I did some data caching and utilized RadGrid's client data-binding capabilities. Data is retrieved from an ASMX web service. Unfortunately I couldn't find a good demo implementing web server data-binding and NestedViewTemplate's/DetailTables'...

Consider a markup like this one:

    
                    <telerik:RadGrid ID="Grid1" runat="server"> 
        
                        <MasterTableView HierarchyLoadMode="ServerOnDemand"> 
        
                            <Columns> 
        
                                <telerik:GridBoundColumn DataField="Date" HeaderText="Date" DataFormatString="{0:D}" /> 
        
                                <telerik:GridBoundColumn DataField="Source" HeaderText="Source" /> 
        
                                <telerik:GridBoundColumn DataField="Subject" HeaderText="Subject" /> 
        
                            </Columns> 
        
                            <NestedViewTemplate> 
        
                                <asp:Label ID="LblBody" runat="server" Text='<%# Bind("Body") %>' meta:localize="false" /> 
        
                            </NestedViewTemplate> 
        
                            <NestedViewSettings> 
        
                                <ParentTableRelation> 
        
                                    <telerik:GridRelationFields MasterKeyField="NewsID" DetailKeyField="NewsID" /> 
        
                                </ParentTableRelation> 
        
                            </NestedViewSettings> 
        
                        </MasterTableView> 
        
                        <ClientSettings> 
        
                            <DataBinding Location="~/GridFeeder.asmx" SelectMethod="GetNews" SelectCountMethod="GetNewsCount" /> 
        
                            <Selecting AllowRowSelect="True" /> 
        
                        </ClientSettings> 
        
                    </telerik:RadGrid>

It would be nice if I could somehow attach a select method to the NestedViewTemplate in order to retrieve a news by NewsID and still use a web service for that.

I've got an almost identical issue with DetailTables - I can't set a web service method to retrieve the appropriate data filtered by NewsID.

I know I can achieve this by using ObjectDataSource but I can not (correct me if I am wrong) point it to an arbitrary web service.

Any help would be greatly appreciated.
Thank you.

Combo box wont receive focus in Edit Form

I am using a POPUP edit form for my grid and I set focus to a control in the ItemCreated event. This works fine for textboxes but when I try to set focus to a RadComboBox it does not work. I do not receive an error, focus is just never set.

Anyone know how to make this work or explain what I may be missing here?

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

If (TypeOf e.Item Is GridEditFormItem AndAlso _
e.Item.IsInEditMode) Then

Dim cboOrg As Telerik.Web.UI.RadComboBox = CType(e.Item.FindControl("cboOrgId"), Telerik.Web.UI.RadComboBox)
cboOrg.Focus()

End If

end sub
