Combobox cell problem

[David Loomes]

Hi,

I''ve been having a problem with a grid containing a column of combobox cells where I cannot select some of the items in the drop down list.

For example I am using the cell to select an arithmetic operator (=, <>, <, <= etc) and for some reason it is impossible to select the ''<'' option even though it appears correctly in the drop down. The problem appears when the list is populated manually or from a DataTable in a data bound control.

Any Ideas?

There were problems of this nature in 1.6.1.8 and earlier versions.

Have you tried this in 2.0.3.0?

I''ve been having a similar problem and I am working with the latest release of the Grid.

Can you post a small sample project so we can see the problem here?

Clay, the problem seems to involve use of the Exclusive dropdown style.

The following code produces the problem

// build the set of allowed operators
StringCollection OperatorChoices = new StringCollection();
OperatorChoices.AddRange(new string[] {"", "=", "<>", ">", ">=", "<", "<=", "Like", "IsNull", "IsNotNull"});

GridStyleInfo Style = grid.ColStyles[1];
Style.CellType = "ComboBox";
Style.CellTipText = "Operator";
Style.DropDownStyle = GridDropDownStyle.Exclusive;
Style.CellValueType = typeof(string);
Style.ChoiceList = OperatorChoices;

You should find it impossible to select "<". Comment out the line that sets the DropDownStyle, and everything works fine.

I tried your code in this project with both 1.6.1.8 and 2.0.3.0, and was able to select the <. Do you see the problem in the sample? What version are you using?

[David Loomes]

Clay,

The sample project you sent shows the problem on my system - I cannot select or type ''<''.

The release notes with my installation describes itself as version 1.6.1.0. Is this the correct place to look?

How can I get 1.6.1.8?

Yes, 1.6.1.0 did have this problem.

You can download 1.6.18 from your Direct Trac home page.
