Hi there,
I'm using a RadGridView with a DateTime column. The property for this column is a nullable DateTime property. I read on a few forum posts that I need to add a FilterDescriptor for the nullable DateTime columns manually. So I added the descriptors the following way:
FilterDescriptor desc = new FilterDescriptor();desc.Operator = FilterOperator.IsEqualTo;desc.Value = null;desc.IsFilterEditor = true;col.FilteringMode = GridViewTimeFilteringMode.Date;gv.Columns["WishDate"].FilterDescriptor = desc;When the data binding is complete, it instantly filters for null value in this column. But I don't want to filter right away. When I don't add the FilterDescriptor, the default FilterOperator for this column is "None".
What I need on startup is this nullable DateTime column with "Equal To" filter and not already filtered data.
I hope you know what I mean :)
Regards,
Danilo

Hello Danilo,
The solution for this will be to create a custom cell and set the operator without applying the filter. Here is the code:
To use the above class you need to handle the CreateCell event:
I hope this will be useful. Let me know if you have additional questions.

class MyGridFilterCell : GridFilterCellElement{ public MyGridFilterCell(GridViewDataColumn column, GridRowElement row) : base(column, row) { } bool flag = true; protected override void UpdateInfoCore() { base.UpdateInfoCore(); if (flag) { this.SetFilterOperator(FilterOperator.IsEqualTo); flag = false; } }}To use the above class you need to handle the CreateCell event:
private void RadGridView1_CreateCell(object sender, GridViewCreateCellEventArgs e){ if (e.CellType == typeof(GridFilterCellElement)) { e.CellElement = new MyGridFilterCell(e.Column as GridViewDataColumn, e.Row); }}I hope this will be useful. Let me know if you have additional questions.
