Hi,
I have this scenario
an aspx page with masterpage. The masterpage has a combobox control, as that value changes an event is raised.
I catch it this way

Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

AddHandler Master.supplierChanged, AddressOf onSupplierChanged

End Sub

Protected Sub onSupplierChanged()

RadGridNMBacheche.Rebind()

End Sub

and then on needdatasource fill the datasource with businness object

Protected Sub RadGridNMBacheche_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGridNMBacheche.NeedDataSource

Try

Dim NM As New NewsManager.CNewsForMyself(myConn)

Dim myDataset As DataSet = NM.getNewsForMyself_asDataset(OrderMode)

RadGridNMBacheche.DataSource = myDataset

Catch ex As Exception

Call LogManager.WriteToErrorLog(errorPath, ClassName, System.Reflection.MethodBase.GetCurrentMethod.Name.ToString(), ex, Err())

End Try

End Sub

So, as combobox value changes my grid changes as well (myconn changes), unless mydataset (the datasource) is nothing,
in this case grid does not refresh and still shows old records. ajax or not ajax is the same.

How to remove html tags from Radcombobox on event of onblur

Hi,

I am using rad combobox and i want to do that when any <HTML> tag insert in combobox after that user go to click GO button than it should become HTML. I am able to do it on simple asp text box but not able to do it on combobox.

Code example:

On TextBox :
<script type="text/javascript">
        //remove space from log text box
function RemoveSpecialSymbols(id) {
            var objid = document.getElementById(id);
            if (objid)
                objid.value = html2entities(objid.value);
        }

        function html2entities(sometext) {
            var re = /[<>]/g
            //    if (sometext.length > 2500)
            //        sometext = sometext.substr(0, 2500);
            return sometext.replace(re, function (m) { return replacechar(m) })
        }

        function replacechar(match) {
            if (match == "<")
                return ""
            else if (match == ">")
                return ""
        }
</script>
<asp:TextBox ID="txtEmail" runat="server" TabIndex="1" MaxLength="50" SkinID="RequiredTextBox" onkeydown="javascript:if (event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {RemoveSpecialSymbols(this.id);}};" onblur="RemoveSpecialSymbols(this.id);" ></asp:TextBox>

Same thing i want to do it on RadCombobox....

     <telerik:RadComboBox ID="RCBSearch" runat="server" Width="250px" Height="150px" Text=""
                    ShowToggleImage="false" EmptyMessage="Search by tags, products, business name"
                    EnableLoadOnDemand="true" ShowMoreResultsBox="true" Style="float: left; margin: 0;
                    padding: 0;" EnableVirtualScrolling="true" ShowDropDownOnTextboxClick="false"
                    onkeydown="PressKeyForProfile(this, event)">
                    <WebServiceSettings Method="GetCompanyNames" Path="wsSellWithMe.asmx" />
                </telerik:RadComboBox>

But it is sowing some kind of javascript error...

"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500"

Thanks
Manish

Ecxeption while Grouping

hi all
I am using radgrid in my application , in that i need to enable the grouping feature, so i set AllowGrouping=true , ShowGroupPanel = true and AllowDragtoGroup = true. It works fine when i try to drag and drop a integer type column(eg:Salary) into the groupPanel but when i drag and drop a string type column(eg: Product Name) it throws an exception like "Could not find the column" or "Could not find the column index -1(Out of Range Exception)".

When the column name contains Space in it (eg: Product Name) the exception is like " Cloud not find the Column Product" i.e., it does not read the Name in Product Name.

Please tell me how to fix this issue it is very urgent.

Thanks in Advance

Dynamic RadSiteMap , IE9 rendering issue

Hello,

I have a radmenu in aspx page and i am adding radsitemap dynamically to radmenuitem.
I am adding radsitemapnodes to radsitemap.
I am using IE9, if i run my application in compatible mode then it works fine.
OR
If i add <meta http-equiv="X-UA-Compatible" content="IE=8" /> in the HEAD section then also it works fine.
In the above two scenarios i was able to see radsitemapnodes with bullets on the left side.
But, if i open my application in normal mode in IE9,then whenever i hover on the menuitem i can see the text of the radsitemapnodes but
the bullets are invisible.
if i click on the menu or if i do some click action on the menu then all bullets are visible .From then i was able to see the bullets in the
Radsitemap.

Does anybody aware of this issue.
Is this the issue with IE9?
Is there any workaround for this?

Please assist.

Thanks,
LV

exception of type 'system.outofmemoryexception' was thrown.

Hi,

It seems like "exception of type 'system.outofmemoryexception' was thrown" is a common error that people are having using the RadGrid; however, I can not find any real solution that works on the forum. My dataset contains 3.5 million records for 80 rows of data.

Regards,

Kelly

Hiding But Not Disabling Scroll

Hello,

I have two RadGrids, g1 and g2, on a page and both have vertical scrollbars. The g1 scrollbar controls the vertical scroll of g2. I would like to hide the vertical scrollbar in g2 but not disable the scrolling.

How is this accomplished?

Thanks,
John S.
