Hi,
       I want to set UseStaticHeader true/false to grid on  button click using java-script. Please Provide help full Solution.



Thanks,
Rahul

I have a RadGrid with client-side binding similar to the "ODataDataSource - Filtering, Sorting and Paging with RadGrid" example.  I have been able to add multiple filter conditions in the past by calling args.set_filterExpressions(filter); multiple times in the "requesting" function (see scripts.js in the example).  However, now I have a specification where I need to search multiple fields for a value (in addition to the other filters on the grid).  So the value might appear in column1,  column2, or column3.  An example of this kind of complex filtering is shown in the list view client-side filtering example. 

What is the recommended way for a client-side bound RadGrid to have complex filtering expressions?  When calling args.set_filterExpressions(filter), any previous expression uses "AND" logic with the existing expressions.  My resulting filter would be an OData URL as in the list view OData filtering example:
((UnitPrice gt 25 and UnitsInStock lt 40) or (Discontinued ne true and startswith(ProductName,'I') eq true))


Thanks.

Hi,

I have problem for RadGrid filtering, even I set CurrentFilterFunction="StartsWith", but filtering always filter as "contains", here is my code for RadGrid, is anything wrong?

thanks

 

<telerik:RadGrid AutoGenerateColumns="false" ID="RadGrid1"

 

 

Width="800px" AllowFilteringByColumn="True" AllowSorting="True"

 

 

ShowFooter="True" AllowPaging="True" runat="server"

 

 

GridLines="None" EnableLinqExpressions="false">

 

 

<GroupingSettings CaseSensitive="false" />

 

 

<MasterTableView AutoGenerateColumns="false" EditMode="InPlace" AllowFilteringByColumn="True"

 

 

ShowFooter="True" TableLayout="Fixed">

 

 

<Columns>

 

 

<telerik:GridBoundColumn FilterControlWidth="60px" DataField="DONOR" HeaderText="DONOR" SortExpression="DONOR"

 

 

UniqueName="DONOR" AutoPostBackOnFilter="true" CurrentFilterFunction="StartsWith" ShowFilterIcon="false">

 

 

</telerik:GridBoundColumn>

........

 

Following this documentation:
http://www.telerik.com/help/aspnet-ajax/combobox-custom-attributes.html

There is no Attributes property for the RadComboBoxItem class... Why?  (See attached.)

Thanks.

Like in this example DEMO, my grid has the ability to show a menu to select and deselect columns. But on the demo, the columns resize to the grid size. Mine doesnt unless some postback is done. How do you resize grid on selecting columns checkbox from the menu?

Edit:
I got this function in javascript that calculate all column width, then apply the width to the grid style. That works well when all columns are there.
Each column must remain at a fixed size (a switch i added with the UniqueName of each column) that way i get the right width. Since i can remove a column, orderIndex can't work here.
So when i click the drop down menu and uncheck a column to hide it, the resize function doesnt work anymore because i can't find the "visible" property of the column, so i get a width containing all columns.
My tableView has a tableLayout fixed.

So, what i need here, is a way to get the visibility of the column to properly resize my grid with it.

Como hago para llenar el radfilter por una function por el codebehind.

Tengo una conexion ya creada a la bd, y estoy buscando por columnas para el lado del cliente, y quisiera obtener estos valores

Is there a way to get an event when the user scrolls from one combobox item to another? I know there are events when the user selects an item, but what about when the highlight comes on?
I'd like to display some additional data related to the item that is highlighted.

Thanks,

Ken

Hi. I have a radGrid with several columns. Some of them are comboboxes and two are RadTextBox. When user type something and press enter it processes the filter and when user clear the TextBox and press enter it clear the filter.
I am using the fuction below which was provided by Telerik.
function TitleKey(event, sender) {
     if (event.keyCode == 13) {
              var filterValue = "";
              var filterFunction = "NoFilter";
              var s = sender.value;
              if (s != "") {
                  filterValue = s;
                  var filterFunction = "Contains";
              }
     var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
     tableView.filter("title", filterValue, filterFunction);
     }
}
However everytime I clear the filter and press enter two steps occur. First it brings the grid as first loaded without any filter, than it brings the right grid with the right result if one or more filter are on.
I have tried to debug it and I cannot find why it is bringing a full grid as first Step.
The other thing is the AjaxPanal does not work properly for this textbox filter compared with the combobox. In the combobox the loading icon is on all post back process. With txtbox you rarely notice it on but when it is gone the application is still processing the grid.

How do i add autonumber to the RadGrid.
i can do in grid like this
<asp:TemplateField SortExpression="displayedname">
                    <HeaderTemplate>
                        Rec #</HeaderTemplate>
                    <ItemTemplate>
                        <%#Container.DataItemIndex+1%></ItemTemplate>
                </asp:TemplateField>

how do i add in radgrid.
