Asked On October 1, 2004 03:26 PM

I am working with Version 2.1.0.9 and was wondering if there is a way to identify what columns from a data set are displayed and what columns are not. Currently I have to create a new data set and copy only the columns I want to have show be in the Data Grid. For Example, if I have a list of States I want to display the name of the state, the state postal abbreviation. But my data set also stores a state code that is reportable to an outside agency and the country code that is associated with the state. I do not want to display the last two values. To reduce database hits I am retrieving the entire table and storing it in memory and I will use the other columns of data information in processing.

Hi Ben, You could hide any number of columns in the MultiColumnComboBox''''s dropdown as shown in the code snippet below : // Show DisplayMember column this.multiColumnBoundCombo.ListBox.Grid.Cols.Hidden[1] = false; // Hide the other columns this.multiColumnBoundCombo.ListBox.Grid.Cols.Hidden[2] = true; this.multiColumnBoundCombo.ListBox.Grid.Cols.Hidden[3] = true; this.multiColumnBoundCombo.ListBox.Grid.Cols.Hidden[4] = true; this.multiColumnBoundCombo.ListBox.Grid.Cols.Hidden[5] = true; Please refer to the sample attached which illustrates this. Thanks for considering Syncfusion products. Regards, Guru Patwal Syncfusion, Inc.
