The current filterable option is set as:
filterable:{operators:{string:{eq:"Equal to"}}},
which produces the following drop down
I wanted to remove the "AND" part so that the drop down looks like this
How do i do that?
If you take a look at the api documentation it shows you this here: remove extra filter option

I am moving to Blazor and attempting to work out how to use custom filtering in Radzen's DataGrid. Here is an example of what I am looking to do (from the old app I need to migrate):
As you can see, there is a filtering section above the grid. Of course I know that Radzen has built-in filtering in the grid itself, but that doesn't help when the filter you want to apply is to a column that is not visible on the grid..
So basically: how do you filter on columns that are not in the grid? I am using OData.. if there is a way I can modify the OData filter when the search button is clicked and reload the grid, that would be helpful.
Sorry if I misunderstood you. As you said, when search button clicked you can load data from the DB by using oData filter and reload the Radzen data grid.
then just call StateHasChanged();
I worked out a solution. You can see it here: https://forum.radzen.com/t/radzen-datagrid-custom-filtering/9448/12
Basically I copied their code from /Radzen.Blazor/QueryableExtension.cs and modified the ToODataFilterString() method to use a collection of FilterDescriptor instead of RadzenGridColumn<T>.. As the name implies, it returns an OData query string.. which I use to filter the grid's data. A working example, with full source code can be found here: https://github.com/gordon-matt/Extenso/tree/develop/Demos/Demo.Extenso.AspNetCore.Blazor.OData
there is a feature called "Filter Row" in Kendo Grid
http://demos.telerik.com/kendo-ui/grid/filter-row
I want to add a drop-down list instead of a text box or a number box, to the filter box. It's for filtering a column that has countries. So I want list of countries in a drop-down list. How can I do this?
It's very similar to the custom Filter Menu (http://demos.telerik.com/kendo-ui/grid/filter-menu-customization). I made the mistake of no using valuePrimitive: true. You might not want it in your situation but keep that in mind.
Here's a sample: http://dojo.telerik.com/OKaS
Also, the filter menu should take up the editor model of the column but it's not always what you want.
Edit
Starting from 2014 Q2 SP1, the template function now receives an object containing "datasource" and "element". In my example, you would have to change the dropdown initialization from "container.kendoDropDownList" to "container.element.kendoDropDownList". The datasource is empty in my example but I'm assuming this can be used to pass the choices to a control without requiring another datasource or to externalize your current. I have not experimented with this feature but I suggest you do before taking my sample blindly.
As Pluc mentioned earlier valuePrimitive: true will help you create a custom filter for your grid/columns to send id's to your controller, if you are not using setting this property true you will receive an Object in your controller instead of a number, the conversion will not be made automatically . This is still working as of 2019
The Search dialog has a drop down item named is in. I like to rename that to something different: Is between
Is it possible to rename it?
If I understand correctly what you need you can use odata option . See the demo from the answer where you will see the operation "from".
On your jqgrid column, change "SearchToolBarOperation" to what operation you need.
I am using custom paging in a RadGrid. It is working fine. But filter is not working as i want. So I thought of writing my own code for filter. But how could i get the filter text and the coloumn for which the filter was applied in the NeedDataSource event.
I got the answer, but I forgot to update here. My bad...
The answer is: gridObject.MasterTableView.FilterExpression. This grid property has all the filters concatenated as a string. this string contains column headers and the filter applied separated by comma ,. You can split that and work on it.
I found another way, which I discovered thanks to ckr's answer here. You need to do this for each filterable column you are interested in:
var filterValue = rgFilterPoints.MasterTableView.GetColumn("YourColumnName").CurrentFilterValue;
Another option, if you happen to be in an event whose EventArgs parameter has Item (like GridCommandEventArgs), you can use this:
((GridTableCell)e.Item.Cells[5]).Column.CurrentFilterValue
You need to use column index in this case. Beware there are a few "hidden" columns at the beginning, so in this example I'm accessing the 4th column in the markup.
How Custom Search Panel In jQgrid example I Want translate search operation example equal to = or greaderthen > or ... or translate to arabic,
thanks all
I have perused the jqGrid wiki and found two pages which might help you.
This page talks about custom searching and its parameters. Notice that you can bind to the beforeSearch event and fire your own function, and parse the search text to accomplish whatever you want.
There is also toolbar searching, which allows custom filtering on each field in your data table. Depending on your solution, you may want to pursue this path. Again, this option also has events that you can bind to if the default search options don't fit your need.
