I have a RadGrid(with Paging) in an updatepanel, and as a result the paging no longer works.
If I do the updatepanel away the paging works, unfortunatly this breaks the page layout.
Any ideas how to get a radgrids paging to work in an updatepanel.

Import Spreadsheet reading row by row

I need to import a spreadsheet into a dataset. The spreadsheets have rows and columns of data, but some of the columns are totaled at the bottom. I think this is giving me error when trying to use the DataTableFormatProvider.Export.

So I want to open the file and read the cells row by row. Are there any examples on how to open a spreadsheet and walk through it row by row?

RadTabStrip - clicking active tab

I'd like to use the tab strip as a filter for a RadGrid below it -- meaning, I won't be using a multipage view but rather every tab will have the same content, just the filter for the radgrid will change based on which tab is selected.

I am using a hierarchical tab scenario, so the primary tabs (pid's are null, therefore root) are usernames, and the underlying ones are prior years of tickets they had. This all works perfectly -- top tabs are their names, and when they click on them, the "current year" of tickets as well as any tickets that are still open are shown (even if they're from prior years). If they want to look at past years, they'd just click on the tab that represents that year number. Each click event fires off a re-bind for the RadGrid below.

All works fine, except for this one problem - once a tab is active, if a user clicks that same tab again, I don't get another click event firing. I'd like to use this re-click as a "refresh" event (meaning the datagrid would re-query the underlying datasource to get up to the minute results).

In the attached picture, if a user selects the first tab (ChCurrier), then selects 2022 to look at last year's tickets, there is no way for him to then re-select the current year's tickets by clicking on ChCurrier again - the click event won't fire because it's already active/selected.

Populating a RadCheckBox from an int column in a datarow

I haven't used Telerik for some time and I'm trying to add a RadCheckBox whose datasource is an integer value in a column of a datarow. In the web page I've got this :

<telerik:RadCheckBox ID="chkProrataEnabled" runat="server" text="" TabIndex="7" Value='<%# DataBinder.Eval(Container, "DataItem.Prorata_Enabled") %>' autopostback="false" OnCheckedChanged="chkProrataEnabled_CheckedChanged">
</telerik:RadCheckBox>

but the check box is not being populated so I'm thinking some form of conversion from int to bool is required but not sure how to go about this. I was thinking I could change the DataBinder.Eval to check the integer value and return a true/false bool ?

I'm missing RadDateRangePicker and nothing else?

The thing about the below error is that I have working controls on the page I'm using, it's just this one control that's missing. Why is that? Is my version too old and this isn't available in that version? The Telerik.Web.UI version is 2014.1.416.35, and yes, I know it's old, but it's what I've got.

Help?

RadChart Input value is invalid

We have developed an application which uses Telerik Radchart controls and it all works successfully on 2 webservers, one here in South Africa (culture EN-SA) and one in the UK (En-UK). However, when is was deployed to a clean Windows 2008 server in Italy (culture IT-Italian) the error below occurs. Thinking that this was culture specific I changed it to En-SA but we still get the error. There was a similar post on your system from Sep 2009 but no solution was posted so I am asking for your help.

Disable Case Sensitive in Telerik Rad ComboBox

I have used a telerik Rad combobox in my ASP.NET web application.

With the help of stored procedure Rad combobox will list some user email-id's.

User will enter minimum 3 characters or paste the input mail in the Rad combobox.
It is failing for some scenarios.

For Example,
The user email id in stored procedure is "Abc@ymail.com".

When user manually typed as "abc@ymail.com", Rad combobox displays the exact match and
when user paste input value as "Abc@ymail.com" and while Left click on outside of the comboBox, it displays the exact match but
when user paste input value as "abc@ymail.com" and while Left click on outside of the comboBox, it is not displaying the exact match.

I tried by changing input text value , rad ComboBox id value and Stored procedure values to lower.
But it doesn't meet my requirements and there is no impact on application.

Note: There is no issue in Stored Procedure, it returns the result inspite of Lower and Upper case.
Kindly suggest me a solution.

Thanks in Advance
