If I want to not show any search results until the user has typed in at least two characters, is that possible? If so, can you point me to documentation on this or an example. I've been looking through the SearchLookUpEditStyleSettings documentation and don't see how to accomplish this.
Should I be creating a new ticket when I have a followup question like this?
Thanks again,
Bill
Hi Bill,
Our LookUpEdit provides a different searching mechanism. In the SearchLookUpEditStyleSettings, the FindMode property specifies the conditions under which the search can be started.
If the FindMode is set to Always, the search will be started after a small delay. It is done in order not to start the search when a user has not yet ended typing the condition string. This delay can be specified via the DataViewBase.SearchDelay property. To change the delay, set this property for the grid's view in the popup content template.
Does this capability meet your requirements?
I apologize for this misunderstanding. The cause of this exception is that version 12.1.4 does not contain the {dxgt:TableViewThemeKey ResourceKey=SearchPanelWidth} theme key. To fix this exception, simply do not use this resource:
XML<Style x:Key="{dxgt:TableViewThemeKey ResourceKey=SearchPanelContentTemplate}" TargetType="{x:Type ContentControl}">
<Setter Property="dx:FocusHelper2.Focusable" Value="False"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Grid Background="{DynamicResource {dxgt:TableViewThemeKey ResourceKey=SearchPanelBackground}}">
<local:MySearchControl x:Name="PART_SearchControl" Width="260" .../>
<!-- ... -->
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Let me know if you need further assistance.
Thanks
Thank you for that width correction. When I run the sample, as soon as I click on the column, I see the list of items. The search does indeed wait until you type multiple characters, but the list is already showing. My customer's desire is to hide the complete list, and only display portions of list that match the search after typing characters. Is there a way to hide the selection items until the search a number of characters has been entered?
Thanks again,
Bill
You can implement this functionality by overriding the UpdateFilterCriteria in the MySearchControl class. In this method, modify the FilterCriteria property if the SearchText is empty in the following manner:
C#protected override void UpdateFilterCriteria() {
if(ColumnProvider == null) {
FilterCriteria = null;
return;
}
if(string.IsNullOrEmpty(SearchText)) {
FilterCriteria = SearchControlHelper.GetCriteriaOperator(ColumnProvider, FilterCondition, Guid.Empty.ToString(), CriteriaOperatorType);
return;
}
FilterCriteria = SearchControlHelper.GetCriteriaOperator(ColumnProvider, FilterCondition, SearchText, CriteriaOperatorType);
}
If you have additional questions, feel free to reactivate this thread.
Thanks
