IE 11 Bugs still Exist with Browser File

http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/incorrectly-rendered-webpage-when-using-internet-explorer-11.aspx

In the above post the Telerik Admin suggested a browser file fix which worked very well for my Windows 7, IE 11 machine.

However it did not fix Windows 8.1 IE11. The problem exists until you switch to compatibility mode.

Is there something else we can do to the browser file until we resolve the impact of upgrading to .Net 4.5?

thanks,

Tim Kelley

[Solved] Radgrid with Dynamic Columns bound to excelworkbook dropping columns

I have an excelworkbook the user has saved to the server.
I have a radgrid that is being databound to this excel workbook.
This workbook can have varying number of columns so I cannot hardcode the columns

Each column will have various datatypes in them.. For example
Column 1 will be mixed alphanumeric values
Column 2 will be dates
Column 3 will be mixed alphanumerics

When I bind the excelworkbook to the radgrid all of the alpha numeric columns (Letters and numbers) do not show up..

ANy idea on how to fix this issue?

I am using the following code plex project to translate the excel workbook into a dataset with tables for each tab in the excel workbook:
http://exceldatareader.codeplex.com/

The code that actual binds the radgrid:

protected DataSet Data

{

get

{

if (Application["data"] == null)

{

return null;

}

return Application["data"] as DataSet;

}

private void ImportFromExcel()

{

// Bind Data and populate Dropdown

string filePath = String.Format("~/ImportProduction/{0}", FileName);

FileStream stream = File.Open(Server.MapPath(filePath), FileMode.Open, FileAccess.Read);

IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);

excelReader.IsFirstRowAsColumnNames = firstRowIsHeaderRowCheckBox.Checked;

Application["data"] = excelReader.AsDataSet();

excelReader.Close();

foreach (DataTable t in Data.Tables)

{

var name = t.TableName;

var index = Data.Tables.IndexOf(t);

RadComboBoxItem item = new RadComboBoxItem(name, index.ToString());

RadComboBox1.Items.Add(item);

RadGridImport.Rebind();

}

protected void RadGridImport_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

if (Data != null)

{

var selectedWorkSheet = RadComboBox1.SelectedIndex;

if (selectedWorkSheet != -1) (sender as RadGrid).DataSource = Data.Tables[selectedWorkSheet]; ValidateButton.Enabled = true;

}

I am having this issue since very long that Filter Icon of GridNumericColumn is not displayed Properly.
See Attached Image. It happens only in IE7. Above IE7 it works perfect. And also it happens with GridNumericColumn
Column only. It works with BoundColumn.
I am using following code and css as it suugests in some of telerik forum but it doesn't work.

<telerik:GridNumericColumn DataField="abc" HeaderText="abc" UniqueName="abc"

FilterControlWidth="80%" SortExpression="abc" FilterListOptions="VaryByDataType"

Resizable="true" AutoPostBackOnFilter="false" ShowSortIcon="true" DataType="System.Int32">

</telerik:GridNumericColumn>

<!--[if IE 7]>

.riTextBox,.riFocused,.riEnabled,.riHover

{

height:15px !important;

}

#ctl00_ContentPlaceHolder_grdAppointmentSearch_ctl00_ctl02_ctl03_RNTBF_abc

{

width:50px !important;

max-width:50px !important;

}

</style>

Default sort order?

Hey,

Trying to make a grid sort a column in descending order after clicking once on the header instead of the default ascending first. Essentially, the behaviour of this demo. From this documentation I get the impression that I can just do this from markup, as the demo does it by creating a SortExpression from code behind. I tried this in my code, and I'm not seeing a behaviour difference.

It's for Telerik 2010Q2 release, without the service pack.
VS2010, .NET 4.

The relevant grid markup follows. It pulls from a LinqDataSource, declared by DataSourceID.

<MasterTableView DataKeyNames="ReportID">

<SortExpressions>

<telerik:GridSortExpression FieldName="ReportSeverityLevelID" SortOrder="Descending" />

<telerik:GridSortExpression FieldName="ReportSeverityColumn" SortOrder="Descending" />

</SortExpressions>

<Columns>

<telerik:GridTemplateColumn HeaderText="Severity" HeaderStyle-Width="45px" SortExpression="ReportSeverityLevelID" UniqueName="ReportSeverityColumn" AllowFiltering="false">

<ItemTemplate>

<asp:Image ID="Image3" runat="server"

ImageUrl='<%# string.Format("~/Images/{0}", ReportSeverityLevel.GetReportSeverityLevel(r=>r.ReportSeverityLevelID==(int)Eval("ReportSeverityLevelID"),r=>r.IconImageFile)) %>' ImageAlign="AbsMiddle"

AlternateText='<%# ReportSeverityLevel.GetReportSeverityLevel(r=>r.ReportSeverityLevelID==(int)Eval("ReportSeverityLevelID"),r=>r.Name) %>' ToolTip='<%# ReportSeverityLevel.GetReportSeverityLevel(r=>r.ReportSeverityLevelID==(int)Eval("ReportSeverityLevelID"),r=>r.Name) %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

Not, I tried the sort expression by column name just in case, as the documentation suggests it should be by the DataSource field, which the first SortExpression for FieldName ReportSeverityLevelID is.

Thanks for any ideas.

How To Databind LightBox ItemTemplate

I have a lightbox setup with an ItemTemplate, I am displaying html text (not images like the data binding examples). I have an asp.net label inside my ItemTemplate that I want to bind the lightbox control to a list of strings and show the string inside of the label. I tried <%# Eval("mypropname")%> inside of the label but get a "Value of type 'System.Web.UI.Control' cannot be converted to 'Telerik.Web.UI.RadLightBoxItem'.

All of the Data* properties exposed server side appear to be specific to displaying images in lightbox. Is there a way to databind a lightbox with a custom item template to a list of strings? If not, is there a way to manually add these items to the lightbox server side?

Thanks!

Render RadDropdownlist from C# code behind

Hello

Current Scenario: Currently we are generating html select (dropdown) from code behind using string builder and adding the generated HTML into literal control - which will display the HTML. Below is the code snippet.

html.Append("<select name=test id=test class='xyz' onchange=\"changeDD(this);\" >");
html.Append("<option value='1'>xyz</option>");

We have number of controls being rendered dynamically based on customer settings. Now, We are trying to replace this html select (dropdown) with Telerik RadDropdownlist.

Please suggest the approach or provide your inputs to achieve this kind of HTML rendering from code behind. Also we have JS written for some of the controls.

Please let me know if you need more details.
