Questions on UI for ASP.NET AJAX Forum

Since I never received a response from this thread: http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/inherited-page-classes-problem.aspx

I'll post here.

In using v. 2008.2.826.35 i wasn't having any problems with the RadGrid. However, when I tried using build 2008.3.1125.35, i began having insert/update issues.

On insert, empty strings (not NULLs) are returned to my app and therefore empty strings are being inserted into my DB.

On update, the original values are being 'updated' in the database - not the new values.

As you can see from the link above, I'm using OnNeedDataSource, so I don't believe the issue is with a PostBack. AND, like i said earlier, everything works perfect with the 2nd Quarter Release. There's a bug somewhere in your 3rd quarter.

Thanks,
Joshua

ComboBox value filled with node text instead of the node value after the second postback

I have an AJAX ComboBox Control and I added an AJAX Treeviw Control inside the ComboBox Item Template. When the post back happened for the second time the ComboBox Value come up with the node text value instead of the node value.

I want to store the Selected Node Value in the ComboBox Item(0).Value and to store the selected node text to the ComboBox Item(0).text and I want them to survive postbacks.

Is this passable? How can I do it?

When I use the following statements:

comboBox.get_items().getItem(0).set_text(node.get_text());

comboBox.get_items().getItem(0).set_value(node.get_value());

I get an error.

Please I need your help.

Thank you.

Selected rows in a grid grouped by two columns

Hi,

I am using following code to get all the rows (checkboxes) that have been selected by a user:

    
            function GetSelectedRows()  
        
            { // get all the rows with the checkbox checked  
        
                var strTickets = "";  
        
                var grid = window["<%= RadGrid1.ClientID %>"];  
        
                var masterTableView = grid.MasterTableView;  
        
                for (var i=0; i<masterTableView.Rows.length; i++)  
        
                {              
        
                    var cell = masterTableView.GetCellByColumnUniqueName(masterTableView.Rows[i] , "TemplateEditColumn");  
        
                    alert("cell=" + cell);  
        
                    var checkBox = cell.getElementsByTagName("INPUT")[0];  
        
                    if (checkBox && checkBox.checked)  
        
                    {  
        
                        var cellID = grid.MasterTableView.GetCellByColumnUniqueName(masterTableView.Rows[i], "TradeTicketID");  
        
                        strTickets = strTickets + cellID.innerHTML + ",";  
        
                    }  
        
                }  
        
                return strTickets;  
        
            }

Everything works fine when there is no grouping, or if the grid is grouped by one column. But when I group by two columns, it doesn't work. It fails on alert("cell=" + cell) with "cell=undefined". Any ideas?

We are using RadGrid v2.0.50727, this project was developed last year.

Thank you,
Julia

bubbling event from RadTreeView UC to main page

Hi All

I have moved the RadTreeView to a UC.

How i wish that when the user clicks on a node, the event is bubbled to the main page, and then the RadGridView is bound.

At the moment in the UC, I have the following:-

protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)
    {
        //lblError.Visible = false;
        //lblError.Text = "";
        RadTreeNode nodeEdited = e.Node;
        ViewState["nodeLevel"] = e.Node.Level;
        ViewState["FullPath"] = e.Node.FullPath;
        ViewState["Value"] = e.Node.Value;
        //pnlCrawledBuildDetailExtended.Visible = false;
        BindGridView();
    }

How can I bubble the BindGridView() to the Main Page, and bind the gridview on the main page?

Thanks for your help

[Solved] Size of FormatStripper drop down

Hi,
is there a way to increase the width of the FormatStripper drop down menu? German text is too long and causes line breaks. Width is set to 200px in the style attribute and I can't find a way to change that programmatically.
