Hi,

The purpose of the input mask is to aid with the drop down's AutoSuggest capabilities.

It is rather cumbersome for a user to type in: 243-6577-1... to find all entries starting with this string. I was hoping to mask the input to automatically include the dash (-) and make things a little easier.

Thanks.

I believe I am having a problem with these timing issues. 

There is another column in my grid which is a "Filter" field used to manipulate the drop down. However, the "Filter" field cannot access the ColumnFilters because they don't exist until after the drop down has been painted?

Sorry I'm not entirely sure what happens after the InitialzeLayout event is fired.

Once the drop down has been painted the ColumnFilters are populated and work as expected. 

EDIT:

Looks like I can just use the Paint event as a pseudo-AfterDropDown event that the DropDownEditorButton doesn't have. This solves my filters problems!

Thanks for all your help Mike.

Okay, I think I see the confusion. There are two different ways to specify ColumnFilters based on the RowFilterMode property.In fact, the ColumnFilters property exists on two different objects.

The code you have here is attempting to clear the ColumnFilters on the Rows collection of the grid. This will not work for the root band and it won't have any effect on any band unless your RowFilterMode is set to SiblingRowsOnly (which is not the default).

If your RowFilterMode is the default or you want to clear the filters on the root band, you should be using the ColumnFilters on the band, not the Rows collection:

this.m_AccountDropDown.,DisplayLayout.Bands[0].ColumnFilters["Client_Id"].ClearFilterConditions();

I'm still not sure what dropping down a DropDownEditorButton has to do with this. I don't see how they could possibly have any effect. Unless maybe you are setting up some ColumnFilters in code and there is some sort of timing issue because the grid hasn't painted, yet. But that doesn't seem likely.

This code: 

this.m_AccountDropDown.Rows.ColumnFilters["Client_Id"].ClearFilterConditions();

Cannot be executed as the ColumnFilters array has a length of zero. Once I have clicked the DropDownEditorButton and the drop down has been displayed (The _InitializeLayout method has already been called at this point.) the ColumnFilters is populated and I am able to continue without error. 

So the question is, which methods need to executed in order to populate the ColumnFilters array?

Hi,

I don't understand your question. What exactly do you mean by "initialized".

I am using ColumnFilters to work alongside the EditorWithMask control and it works well. 

I am having a small issue with the ColumnFilters not being initialized until after I do a DropDown() of my grid. How can I avoid doing this or - what methods are called during the drop down that construct the ColumnFilters?
