How to achieve different filtering for different columns in RadGrid

[Bibhudutta]

I am new to Telerik. I have implemeted Telerik RadGrid, in that I have "Conatins" as the default Filtering option for all columns. But now I want it to be specific to some columns. Thats means for few columns I want "Contains" as the filtering option and for few I want "EqualTo" to be the filtering option. I have " Google Like " filtering, so no filter button next to the textbox feild to display the filter options. How can I achieve this ?

Please Help me out . Thanks.

Hello,

You can reduce the filter options as per your requirement. Check the following help documentation which explains more about this.

Hi,

You need to change the implementation of the SelectedIndexChanged event in the custom filter column class:

private void list_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            GridFilteringItem filterItem = (GridFilteringItem)((RadComboBox)o).NamingContainer;
            if ((this.UniqueName == "Index"))
            {
                //this is filtering for integer column type
                filterItem.FireCommandEvent("Filter", new Pair("EqualTo", this.UniqueName));
            }
            //filtering for string column type
            filterItem.FireCommandEvent("Filter", new Pair("Contains", this.UniqueName));
        }

You could follow the same approach, you should only change the conditions in the if statements  to check whether the desired ComboBox is the one that is created and then to assign the required filter function.

Give this approach a try and check whether this is the desired behavior.
