Is it possible to set the maxlength on the filter item?

Ironically, the filter item seems to inherit most of the column properties, data type for example, but it ignores the maxlength property. I have a field that is an int16, but I want to limit the user from typing in more than four numbers.

Also, I don't want to show the comma if the value is greater than 999.

I would prefer not to have to go to the trouble of creating FilterTemplates if possible. It is a shame that there don't seem to be more filter properties in the grid column.

Here is the solution:
        protected void RadGrid_ItemCreated(object sender, GridItemEventArgs e)  
        {  
            if (e.Item is GridFilteringItem)  
            {  
                TextBox txtClientAssetId = ((e.Item as GridFilteringItem)["ClientAssetId"].Controls[0] as TextBox);  
                if (txtClientAssetId != null)  
                {  
                    txtClientAssetId.MaxLength = 20;  
                }  
 
                TextBox txtAddress = ((e.Item as GridFilteringItem)["Address"].Controls[0] as TextBox);  
                if (txtAddress != null)  
                {  
                    txtAddress.MaxLength = 20;  
                }  
            }  
        }  
 
 

but I have to say, what a huge pain in the a##. I am not a fan of the radgrid filtering. I am going to revert their filters and just create my own. The implementation is a real drag.

Things that could make it much nicer:
1) A setting for max length on the filter control.
2) A global setting for filter menu items by data type. If I could go in and say I want the following menu items for all int32 filters, that would be awesome.
3)  An option to display a button to reset all filters
4) an option at the grid level to use a search button to start the search rather than an autopostback for each filter selection.

Hello Jim,

Indeed, this is one possible option to handle the desired setup.
Another option is to use a filter template, and define the look and feel of the filter menu for a given cell manually. This gives you the greatest flexibility, without having to write much code. Additional information on this option is available in the following example:

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx

I hope it gets you started properly.

Best wishes,
