When filtering for a negative number in a GridNumericColumn with a Numeric Type of "Currency" and  AutoPostBackOnFilter="true"  filter loses its negative value on Enter keypress.

Setup to reproduce:

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" Width="800px" OnNeedDataSource="RadGrid1_NeedDataSource"
    <MasterTableView AutoGenerateColumns="False">
            <telerik:GridNumericColumn DataField="Price" DataType="System.Decimal"
                FilterControlAltText="Filter Price column" HeaderText="Price"
                SortExpression="Price" UniqueName="Price" NumericType="Currency" 
                AutoPostBackOnFilter="true" CurrentFilterFunction="EqualTo">


protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    (sender as RadGrid).DataSource = Enumerable.Range(1,6).Select(x=> new { Price = Math.Pow(-1, x) * (x * 0.1 + x * 0.01) });
Type a negative value e.g. "-0.11" in the filter control and press Enter. The filter value changes to a positive one and then the filter applies.

Update: Items is marked as Won't Fix as the behavior is expected and is due to the nature of the batch mode. Changing it will result in a breaking change.

Hi Team Telerik,

i found a bug in RadGrid. This one only appears in Chrome Webbrowser.
Columnresizing only works once per column in chrome. You can see it right the way in your demo-site. Go to the Resizing Demopart and resize one column. Now try to re-resize it. It wont work. 

Best wishes Philipp

RadGrid throws a "Failed to load viewstate" exception in a specific setup with two level hierarchy and DateTimeColumns. 

Steps to reproduce:
1. Expand an item
2. Click on "Add new record button" in the expanded detail table view
3. Click "Cancel"
4. Click on"Add new record" this time on the master table view

Code to reproduce:

<telerik:RadGrid ID="rgComments"
    <MasterTableView Width="100%"
        CommandItemDisplay="Top" DataKeyNames="OrderID">
            <telerik:GridTableView DataKeyNames="OrderID" DataSourceID="dsComment" Width="100%"
                runat="server" CommandItemDisplay="Top">
                    <telerik:GridRelationFields DetailKeyField="OrderID" MasterKeyField="OrderID"></telerik:GridRelationFields>
                    <telerik:GridDateTimeColumn DataField="OrderDate" PickerType="DateTimePicker">
            <telerik:GridDateTimeColumn DataField="OrderID" />
<br />
<asp:SqlDataSource runat="server" ID="dsComment" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
    SelectCommand="SELECT [OrderID], [OrderDate] FROM [Orders]"></asp:SqlDataSource>
<asp:SqlDataSource runat="server" ID="dsSpell" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
    SelectCommand="SELECT [OrderID], [OrderDate] FROM [Orders]"></asp:SqlDataSource>

When Scrolling is enabled with Frozen columns in RadGrid, horizontal scrollbar not visible in Microsoft Edge.

Issue appears in Microsoft Edge Version:
- Microsoft Edge 42.17134.1.0
- Microsoft EdgeHTML 17.17134


Apparently, setting the horizontal scrollbar's height to 17 pixels will make Microsoft Edge display it. (Note: in case it still not displaying, you may try with 18px)

To set the height, you can choose one of the options below:

1. Using CSS style to increase the size of the horizontal scrollbar by one pixel.

<style type="text/css">
    .RadGrid div[id$="_Frozen"] {
        height: 18px;

        /* or  */
        /*padding-bottom: 1px;*/

2. Using JavaScript

Subscribe the grid to its GridCreated client-side event, and in the event handler increase the element's height with the scrollbar then revert it back to its original size with a delay:

<script type="text/javascript">
    function GridCreated(sender, args) {

I updated my code with version 2013.3.1114, but the method get_cell() of the GridDataItem has become case-sensitive.
I have some codes that with version 2012.3.1016 that was working correctly.
Is possibile to have the choice of case-sensitive / insensitive or at least have backward comaptibility ?

Because the TBODY THEAD and TFOOT elements are rendered in an incorrect order which is "header -> footer -> body" rather than "header -> body -> footer", the screen readers fail to present the data properly.

The SearchRow in RadGridView WinForms is extremely good.


How can we implement the same in ASP.Net Ajax RadGrid?

In radgrid, when you are filtering the grid using EXCEL like filtering, you get a Listbox where you can enter a filter string, which then shows a filterlist of checkboxes that match that filter string.  There is a checkall checkbox at the very top.  If you select that, it selects all the filtered list checkboxes and checks them.

When you then click the filter button to apply the selection, the filter criteria is ignored, and no grid filtering occurs.

I did find a "fix" for this, but it is not useable.  


The problem with this fix is that it works on the first applied filter, but if you the try to filter again, the Listbox takes a extremely long time to load the checkbox list, and so is not practical.

Is there a better solution?  Has this even been identified as a bug which will be fixed?

Release R2 2021 SP1

When the Grid is set to have FilterType="HeaderContext" and filtering by a keyword that starts with a question mark "?MyKeyword", an exception will be thrown: System.ArgumentOutOfRangeException: Index was out of range.

The issue can be replicated in our online demo Excel-like Filtering.

Note that the demos will not display the exact exception because it is handled by the CustomError mechanism of the demo site.

As a user I would like to see on each grid the aggregate function totals for the actively displayed grid and on the last page the aggregate function totals for the active displayed grid and the data set aggregate function totals so that each page displays only its page level total and on the last page displays the full total of all data displayed.

See attached examples:
Example: Page level Total on every page and on the last page Page level Total plus Grid whole Total on the last page.
