Datepicker width rendering issue in Safari and Chrome filter

I have a grid with a date column. Here is the code:

The grid renders properly and everything looks great in IE and FireFox. However in Safari and Chrome the column width for the Eval Date column is HUGE. If I set AllowFilter="False" for the EvalDate column the grid looks good in Safari and Chrome again.

Is there a work-around for this and is this a known bug?

Thanks,

Dan

IE 7.0 Rad Textbox under Rad Tab Strip is not maintaing width

I've noticed that when we have 2 tabs in a form and have rad textbox controls on both tabs, the tab that is not in focus has controls with different widths than specified in the markup. This is happening in IE 7.0. I have confirmed that this is working properly on all other browsers.

RadGrid RadTreeView LoadOnDemand and NodeTemplate

I had written a page that employed a RadGrid with an EditTemplate that contained a RadTreeView that itself contained a NodeTemplate. It all worked fine until my RadTreeView got too many nodes in it and just ran way too slow. I decided I need to move toward a Load on Demand solution for the RadTreeView. But the complexity of needing to generate a partial tree of templated nodes within an edited RadGrid has proven just more than I can figure out how to do.

So, I've boiled it down to a simple case that I think captures all the important parts of my implementation. There's a commented section in the code-behind that can be uncommented to enable Load on Demand. I didn't supply any of my futile implementations in TreeView_NodeExpand because none of them have worked. I'm asking for what might go in there to make this example work.

My aspx file is:

<%@ Page AutoEventWireup="true" CodeFile="DefaultCS.aspx.cs"

Inherits="Telerik.Web.Examples.Grid.Integration.GridWithTreeViewComboBoxEditors.DefaultCS"

Language="c#" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

</FormTemplate>

// To enable Load on Demand, uncomment these lines

// pNode.ExpandMode=TreeNodeExpandMode.ServerSideCallBack;

// pNode.Nodes.Clear();

// }

}

public void TreeView_NodeExpand(Object sender, RadTreeNodeEventArgs e) {

// What can go in here that will allow me to create nodes according to

Data Source Null when Paging

Hi All,

I'm having some issues building a RadGrid using Advanced Data Binding. I have a grid that is displaying a report that's run by selection options and clicking a button. When the button is clicked the first page generates correctly, but any time you try to use any of the paging (click page number, forward, back) the DataSourse appears to be wiped out and the grid becomes invisible again since it is empty. Any help would be appreciated.

Grid:

<telerik:RadGrid ID="GridComplianceReport" Width="100%"

AllowPaging="True" PageSize="30" runat="server" AllowSorting="true" Visible="false"

OnNeedDataSource="GridComplianceReport_NeedDataSource" GridLines="None" >

<MasterTableView Width="100%" />

<PagerStyle Mode="NextPrevAndNumeric" />

</telerik:RadGrid>

OnNeedDataSource:

protected void GridComplianceReport_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

Employee parentEmployee = new Employee();

Employee childEmployee = new Employee();

if (Session["Employee"] != null)

{

parentEmployee = (Employee)Session["Employee"];

}

if (Session["ChildEmployee"] != null)

{

childEmployee = (Employee)Session["ChildEmployee"];

if (Session["SelectedEmployeeID"].ToString() == parentEmployee.EmployeeID)

{

FillComplianceReport(parentEmployee);

}

else

{

FillComplianceReport(childEmployee);

}

else //no child employee, populate with logged in employee

{

FillComplianceReport(parentEmployee);

}

private void FillComplianceReport(Employee employee)

{

lblReportsHeader.Text = employee.Name;

string who = "";

ArrayList complianceType = new ArrayList();

ArrayList complianceStatus = new ArrayList();

List<Reports> complianceReport = new List<Reports>();

who = rdbEmployeeType.SelectedItem.Value;

foreach (ListItem item in chkComplianceTypes.Items)

{

if (item.Selected)

complianceType.Add(item.Value);

}

foreach (ListItem item in chkComplianceStatus.Items)

{

if (item.Selected)

complianceStatus.Add(item.Value);

}

complianceReport = EmployeeBLL.GetComplianceReports(employee.EmployeeID, who, complianceType, complianceStatus);

Session["ComplianceReport"] = complianceReport;

GridComplianceReport.DataSource = complianceReport;

if (compliancereport.Count > 0)

GridComplianceReport.Visible = true;

ReportsExceptionPanel.Visible = false;

}

On Button Click:

protected void btnGenerateComplianceReport_Click(object sender, ImageClickEventArgs e)

{

GridComplianceReport.Visible = true;

GridComplianceReport.DataSource = null;

GridComplianceReport.Rebind();

}

RadWindowManager in UserControl?

Ok, here is my noob question :-)

I have a footer usercontrol (ascx). This footer control launch server side a radwindow (that is another aspx page).

Here is my code:

RadWindow newWindow = new Telerik.Web.UI.RadWindow();

newWindow.ID = "HelpDeskMessageWindow";

newWindow.NavigateUrl = "ErrorPopup.aspx";

newWindow.AutoSize = true;

newWindow.Modal = true;

RadWindowManager1.Windows.Add(newWindow);

newWindow.VisibleOnPageLoad = true;

As you can see in order to do that I have to put the radwindowmanager inside the usercontrol.

I'm worried about this, because I think that the radwindowmanager should stay in the parent aspx page who contains the control.

What is the best way to do that? i'm doing something wrong?
Thanks a lot

Filter feature

I see the RadGrid have Filter feature for every column. Sometimes I want a filter feature like Excel. It means the filter dropdown menu only show those distinct value instead of filter expression. Whether the RagGrid implement the feature?
