Unable to print radgrid in Mozilla for some pages

Hi,
With the help of the posts in http://www.telerik.com/community/forums/aspnet/grid/72051-radgrid-print.aspx#1532370 I could print the entire contents of radgrid in Internet Explorer and mozilla .But I am not able to print the radgrid of certain web pages of the application in same version of mozilla while able to do that in internet explorer.For those pages, the below function PrintRadGrid returns null for $find(radGridId).

For the non-working pages , if i put a alert as the first line of the function PrintRadGrid , then it is working

Could any body please explain why this happens and how to make it working ...

function getOuterHTML(obj) {
            if (typeof (obj.outerHTML) == "undefined") {
                var divWrapper = document.createElement("div");
                var copyOb = obj.cloneNode(true);
                divWrapper.appendChild(copyOb);
                return divWrapper.innerHTML
            }
            else
                return obj.outerHTML;
        }

function PrintRadGrid(radGridId) {

            var radGrid = $find(radGridId);
            var previewWnd = window.open('about:blank', '', '', false);
            var sh = '<%# ClientScript.GetWebResourceUrl(grdName.GetType(),String.Format("Telerik.Web.UI.Skins.{0}.Grid.{0}.css",grdName.Skin)) %>';
            var styleStr = "<html><head><link href = '" + sh + "' rel='stylesheet' type='text/css'></link></head>";
            var htmlcontent = styleStr + "<body>" + getOuterHTML(radGrid.get_element().parentNode) + "</body></html>";
            previewWnd.document.open();
            previewWnd.document.write(htmlcontent);
            previewWnd.document.close();
            previewWnd.print();
            previewWnd.close();

radGrid.get_masterTableView().fireCommand("EnablePaging", "");
}

And in code behind

RadPnl.ResponseScripts.Add("PrintRadGrid('" + grdNmae.ClientID + "')");

Thanks

Slider handle will not slide in IE9

Version: 2011.1.519.35

When you left click down and hold on the slider handle and move your mouse left or right the handle will not move. If you click in front or behind the handle on the slide scale the handle will move. This only happens in IE9.

Can you confirm replication of this issue? If so, when can we expect a fix?

hierarchical grid selected rows. How to get their parents

Hi, I have an hierarchical grid. masterTableView and DetailTables.
DetailTables has a GridClientSelectColumn that allows to select rows (multiselection)

<telerik:RadGrid ID="RadGridResources" runat="server" Width="950px" ShowStatusBar="true"

AutoGenerateColumns="False" PageSize="7" AllowSorting="True" AllowMultiRowSelection="True"

AllowPaging="True">

<PagerStyle Mode="NumericPages"></PagerStyle>

<MasterTableView Width="100%" DataKeyNames="IDResource" AllowMultiColumnSorting="True" HierarchyDefaultExpanded="true">

<DetailTables>

<telerik:GridTableView DataKeyNames="IDSlot" Name="Slot" Width="100%">

<Columns>

<telerik:GridClientSelectColumn HeaderStyle-Width="40px"

UniqueName="CheckboxSelectIDSlotColumn"

>

<HeaderStyle Width="40px" />

</telerik:GridClientSelectColumn>

<telerik:GridBoundColumn SortExpression="IDSlot" HeaderText="IDSlot" HeaderButtonType="TextButton"

DataField="IDSlot">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="Code" HeaderText="Code" HeaderButtonType="TextButton"

DataField="Code">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="Description" HeaderText="Description" HeaderButtonType="TextButton"

DataField="Description">

</telerik:GridBoundColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="IDResource" HeaderText="IDResource" HeaderButtonType="TextButton"

DataField="IDResource">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="Code" HeaderText="Code" HeaderButtonType="TextButton"

DataField="Code">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="Description" HeaderText="Description" HeaderButtonType="TextButton"

DataField="Description">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings enablePostBackOnRowClick="true">

<ClientEvents />

<Selecting AllowRowSelect="true" />

</ClientSettings>

</telerik:RadGrid>

any time a row is selected I would like to get all the selected rows collection. Think can use selectedIndexChanged...

Protected Sub RadGridResources_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGridResources.SelectedIndexChanged

Try

Dim selectedItems As New ArrayList

Dim idSlot As Long

For i = 0 To RadGridResources.SelectedItems.Count - 1

Dim dataItem As GridDataItem = RadGridResources.SelectedItems(i)

idSlot = dataItem("IDSlot").Text

selectedItems.Add(idSlot)

Next

'TO DO

Catch ex As Exception

End Try

End Sub

In the away here above I find all IDSlot (child) selected values but I don't know how to find their IDResource (parent)

Thank you

ComboBox $find returns null

Hi,
I have a rad combobox in Ajax update panel inside an ascx control. I need to show a confirm box every time the combo box is changed based on a condition. If the user chooses not to go with the change, I need to set the combo box value to the previous one.
I was able to use ScriptManager.RegisterStartupScript to show the confirm box from the SelectedIndexChanged event. But I'm not able to set the combo box value to previous one. I keep getting null for $find on the combo box. Please find the related code below. Any help is greatly helpful as I need to resolve this ASAP.

ASCX code:
<telerik:RadCodeBlock ID="rcbCodeBlock" runat="server">

    <script type="text/javascript">
        function ShowConfirmOrgCode(oldValue, combo) {
            if (!confirm('Do you want to continue...?')) {
                var orgcombo = $find(combo);
                if (orgcombo != null) {
                    alert(orgcombo.get_selectedIndex());
                    orgcombo .findItemByValue(oldValue).select();
                }
            }
        }
    </script>

</telerik:RadCodeBlock>

           <asp:UpdatePanel ID="updatePanelOrgCode" runat="server">
                <ContentTemplate>
                 <telerik:RadComboBox ID="ddlOrgCode" Width="300px" runat="server" AutoPostBack="true" Height="100px"
                DropDownWidth="570px" MarkFirstMatch="true" EnableLoadOnDemand="false" />
            <asp:RequiredFieldValidator ID="ddlOrgCodereqval" Enabled="true" runat="server" ControlToValidate="ddlOrgCode"
                Display="None" InitialValue="<<- Select Organization Code ->>" ErrorMessage="Organization code is required."
                ValidationGroup="Group1"></asp:RequiredFieldValidator>
            <asp:HiddenField ID="hiddenOrgCode" runat="server" />
            <asp:HiddenField ID="hiddenHasAccess" runat="server" />
                </ContentTemplate>
            </asp:UpdatePanel>

Code Behind:
        protected void ddlOrgCode_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            if (ddlOrgCode.SelectedIndex != -1)
            {
                OrganizationCodeCollection ogc = base.CurrentPDCreator.GetAssignedOrganizationCodes();
                int selectedOrgCode = Convert.ToInt32(ddlOrgCode.SelectedValue);
                string oldValue = hiddenOrgCode.Value;
                bool hasAccess = ogc.Contains(selectedOrgCode);
                string sorg = ddlOrgCode.ClientID;
                if (!hasAccess)
                {
                    hiddenHasAccess.Value = hasAccess.ToString();
                    string strScript = "setTimeout(ShowConfirmOrgCode('" + oldValue + "', '" + sorg + "'), 500);";
                    ScriptManager.RegisterStartupScript(updatePanelOrgCode, GetType(), "OrgCodePopup", strScript, true);
                }
                else
                {
                    hiddenOrgCode.Value = selectedOrgCode.ToString();
                }
            }

Right-Clicking LinkButton Download to "Save Target As..."

Hi,

I'm using the radbutton with the download icon to allow users to download files.

This works fine in most cases accept for mime types that the browser recognizes and opens directly
in the browser when the user would rather not open the file, but prefers to "Save As..." the file instead.

When I use a standard ASP.net hyperlink the user can either click to open or right click and select
"Save Target As..." and save it without opening it.

Is there any way to make the browsers work this way when using the radbutton as a download hyperlink?

Thank,
Scott

RadMenu z-index overlaying the Sharepoint Site Actions dropdown

I have a RadMenu in a SharePoint master page. The problem is, when I select the site Actions dropdown it appears behind the RadMenu. The Default z-index of the menu is 7000, I’ve set it to (z-index 3 !important) with no change to the issue.

How should I configure the RadMenu to appear below the SharePoint Site Actions Menu, But will still remain above the other Telerik controls.

using jQuery --> server side callback to update a RadGrid

Greetings,

I have a page with a radGrid and a button that allow my user to download a file, now if I use the RadAjax Manger to configure
the button to an AJAX style postback this will confict with the file download -- if you do this you get Parse Error, as you
are messing w/ the server response :)

This page also has a grid that shows the data that is being downloaded with a status column that displays if 'exported' process
has been completed. i.e..(the user downloaded the file)

Here's my goal, user clicks to the get the download, and aspx server side code sub. rgRequests_NeedDataSource is invoked causing the RadGrid to be updated

I am using client side jQuery.to update the text lables on the page with out issue,

but I do not understand how to invoke a server side code (asp.net).



// this is wired up to a ASP:BUTTON -- onClick event



function upDatePAMLabel(label,grid) {

$("#" + label).html("There are no User IDs waiting to be exported");

// AJAX Call back here to refresh the grid

// $("#" + grid).ajax("PortalAdminManager.aspx", "", "rgRequests_NeedDataSource","");

/* does nothing!

$.ajax({

type: "POST",

url: "PortalAdminManager.aspx/rgRequests_NeedDataSource",

data: "{}",

contentType: "application/json; charset=utf-8",

dataType: "json",

success: function (msg) {

alert(msg)

}

});

*/

// brute force method - to refresh the grid

// force a reload so that Request Status is updated in the grid

$(document).ready(function () {

setTimeout(function () { window.location.href = "./PortalAdminManager.aspx"; }, 1000);

});

}

So if anyone has done this, please a post a solution or a suggestion!

Thanks,
