RadGrid Export Problem

Hi

I have an intermittent problem with the radgrid export, soemtimes the code works and exports, sometimes it just flashes the save prompt and goes back to the grid page without doing anything. here is my code.

        protected void cmdExportToExcel_Click(object sender, ImageClickEventArgs e)
        {
            RadGrid1.ExportSettings.ExportOnlyData = true;
            RadGrid1.ExportSettings.IgnorePaging = true;
            RadGrid1.ExportSettings.OpenInNewWindow = true;
            RadGrid1.ExportSettings.FileName = "test";
            RadGrid1.MasterTableView.ExportToExcel();
        }

Data table issue

We've got a radgrid bound to a dataset and a search text box on our web page. When the user inputs a code to the text box, we want the radgrid to find the row within the dataset and scroll down to it in the grid.

This was possible to do in standard VB.NET but we're having issues using telerik.

So far we have this logic:

    
               Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load  
        
                    cn = New SqlConnection(ConStr)  
        
                    ds = New DataSet  
        
                    dv = New DataView  
        
                    Dim ad As New SqlDataAdapter("select * from mytable", cn)  
        
                    ad.Fill(ds, "codeid")  
        
                    dv.Table = ds.Tables("codeid")  
        
                    RadGrid.DataSource = dv  
        
                End Sub 
        
                Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearch.Click  
        
                    Dim lpos As Integer 
        
                    dv.Sort = "codeid" 
        
                    lpos = dv.Find(btnSearch.Text)  
        
                    'here we want to set current row to lpos  
        
                    RadGrid.Rebind()  
        
                End Sub

But when it comes to setting the data set's index we found the property was read only.

RadGrid2.SelectedItems.Item(0).DataSetIndex = 4

Property 'DataSetIndex' is 'ReadOnly'.

Is there another property we have to use instead to achieve the same effect of getting the grid to scroll down to the right place in the dataset position the user searched for?

[Javascript] findItemByText - Returning Null

Dear All,
Problem Statement - I have a popup window, in which I will search and select one item(internally I have two values). On click of a button I need this text to go to parent page and get inserted into a RADCombobox. If that Item is present, the Item will get selected else a new RADCombobox item needs to be created.
Solution - Once I select one item and click button, I am calling a Javascript function in the parent page as below.

self.opener.AddSelectedOilGrade(selValue,selText);

In the parent page I am trying to find the item existing or not and then selecting this item. Below is the code.

var

combo = $find("<%= cboOilinUse.ClientID %>");

var item = combo.findItemByText(strText);

if(item)

{item.select();}

else

{

var comboItem = new Telerik.Web.UI.RadComboBoxItem();

comboItem.set_text(strText);

comboItem.set_value(strValue);

comboItem.select();}

I have refered to the example given in the below URL.
http://www.telerik.com/help/aspnet-ajax/combo_clientsidebasics.html

But this is returning NULL(var comboItem = new Telerik.Web.UI.RadComboBoxItem();).

Please let me know if anything is going wrong.

Hiding expand/collapse images when no records

I am using rad grid in hierarchical mode in my project.
Some of the rows in parent do not have child records, so i am removing the 'plus' sign for those rows. However the rows
are getting misalligned and looking dirty, typically a white border is coming to the left and bottom the cell of the 'plus' sign.

I am not able to provide scrrenshot, otherwise i would have done so.
I have posted a lot of queries before and obtained solution very quickly from your side. So thanks in advance.
Pls advice.

Page communication

I have the following scenario:

I have a radsplitter with 3 panes. - a vertical pane which has a grid with one column called packages. To the right of this pane, I have an embedded splitter with 2 horizontal panes. On the top pane, I have a 4 grids using a tabstrip of all possible items that can be added to a package. The content for the top pane is an aspx page that is also in my project.
In the bottom pane, I want a grid which will be where the user can build the package that they select in the left pane.

When the user clicks a checkbox in the top grid(pane) I want that row to be added to the grid in the bottom pane. I also want to give the user the option to use drag and drop from the top pane grid to the bottom.

Since the top grid (pane) is in a separate aspx page, is there a way for that page on checkbox clicked or on rowDragStarted to communicate back to the parent page what has been done and the data that needs to be communicated back?

Thanks,
Laura
