I've used the Telerik Themebuilder to create a css file for the grid and set up my application to use the theme. This is working however, there are many classes that are not being output by the themebuilder. For instance, the buttons on the pager don't work.
Settings to reproduce the problem:
<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" Width="800px" OnNeedDataSource="RadGrid1_NeedDataSource">
<ClientSettings>
<Scrolling AllowScroll="true" UseStaticHeaders="true" />
</ClientSettings>
<MasterTableView InsertItemDisplay="Bottom"
I have a grid with several columns - so many that they cannot all appear at once. Users are allow to reorder the columns as they wish. If my grid is set to FrozencolumnsCount=0, then when they drag a column to the edge of the grid, the grid starts to horizontally scroll so that they can see additional columns and drop their column in the desired location.
However if I set FrozenColumnsCount=1, then when they drag a column to the edge of the grid, the grid does not horizontally scroll.
The row selection in RadGrid is not proper if the row is deselected via the checkbox, while the Shift button is pressed.
Steps to reproduce the problem:
These issues can be reproduced here:
1. Navigate to the above site on an iOS device (IPhone or IPad).
2. Touch the top right hamburger menu to open the Columns Display Form.
3. Touch a checkbox.
The first touch over a checkbox or its corresponding label is not changing the state of the checkbox but at the same time, the header buttons are switched to Done and Cancel (as if changes have been made).
Touching between separate column fields changes the state of the checkbox of the upper column but the same is not updating the header buttons (Back button remains visible and Done and Cancel remain hidden).

Hi,
Heres a simple one: I have a dynamic grid `MasterTableView.EnableColumnsViewState = false;` on page init and all works fine. However, when the client/browser show a dynamic column thats hidden (or vise versa), and the column is gone on postback (being a dynamic grid this can happen), the LoadClientState tries to get the column - and if it fails to, it breaks down hard.. Instead it should just ignore it, as its just a pretty un-important show/hide state.
Your RadGrid code goes something like this:
LoadClientState ->
if (clientState.ContainsKey("showedColumns")) ->
control.GetColumn(columnUniqueName).Display = true; <-- just ignore this if not found - also on the others like hide, resize etc.
Thank you!... +1 for making this html editor a MD flavor instead :)

Noticed that when using a template to custom define the pager look, the pager gets rendered in a TD and not a TH as expected since the pager is in a THEAD. Could the header pager only be modified to render in TH? This would allow all elements in the header to render the same and help with styling.
HeaderContextMenu filter functions such as "GreaterThanOrEqualTo", "LessThanOrEqualTo" are not working.
This issue happens with the Header Context Menu. The following scenarios are affected:
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"
AllowFilteringByColumn="true">
<MasterTableView AutoGenerateColumns="False">
<Columns>
<telerik:GridNumericColumn DataField="Price" DataType="System.Decimal"
FilterControlAltText="Filter Price column" HeaderText="Price"
SortExpression="Price" UniqueName="Price" NumericType="Currency"
AutoPostBackOnFilter="true" CurrentFilterFunction="EqualTo">
</telerik:GridNumericColumn>
</Columns>
</MasterTableView>
</telerik:RadGrid>
C#
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) });
}
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?

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.
Currently, the Headers are cycled by pressing the Tab key and this FeatureRequest is to improve the behavior and allow arrow navigation between headers, similar to the Kendo UI Grid:
Also, pressing Home/End should navigate to the first/last focusable cell in the row, while Ctrl+Home/Ctrl+End should navigate to the first/last focusable element in the Grid.
Good morning,
we have a strange issue using RadGrid with horizontal scroll and frozen columns: there a resizing of the height which gets user experience not the best.
See attached gif.
Could you please help us?
