Collapsing Constraints on Losing Focus

[Ralf Gnass]

Hello,

there is a problem using the GridDataBoundGrid in Version 3.2.1.0 when it loses the Focus to a RichTextBox, as it seems, and when Constraints are being used to create Hierarchy Levels to be expanded by the User.

When the grid-Focus is lost to a RichTextBox, the whole Grid gets collapsed, and the focus is not being lost. When you try it a second time and the grid is collapsed, it loses the focus.

Any Suggestions?

How do I see the probblem in this sample? http://www.syncfusion.com/Support/user/uploads/GGC_9d8f822f.zip

I tried it both with version 3.2.1.0 and 3.3, and clicking the richtextbox did not seem to collapse any gird nodes for me.

Use the GridDataBoundGrid.

I replaced the GroupingControl with the GridDataBoundGrid in your example with the following Extension to the code:

private void Form1_Load(object sender, System.EventArgs e)
{
DataTable parentTable = GetParentTable();
DataTable childTable = GetChildTable();
DataTable grandChildTable = GetGrandChildTable();

DataSet ds = new DataSet();
ds.Tables.AddRange(new DataTable[]{parentTable, childTable, grandChildTable});

//add the datatables in their nested order
tableLevelList.Add(parentTable.TableName);
tableLevelList.Add(childTable.TableName);
tableLevelList.Add(grandChildTable.TableName);

DataRelation parentToChild = new DataRelation("ParentToChild", parentTable.Columns["parentID"], childTable.Columns["ParentID"]);
DataRelation childToGrandChild = new DataRelation("ChildToGrandChild", childTable.Columns["childID"], grandChildTable.Columns["ChildID"]);

ds.Relations.AddRange(new DataRelation[]{parentToChild, childToGrandChild });

this.gridDataBoundGrid1.DataSource = parentTable;

GridHierarchyLevel level1= gridDataBoundGrid1.Binder.AddRelation("ParentToChild");
GridHierarchyLevel level0= gridDataBoundGrid1.Binder.RootHierarchyLevel;
if(level0!=null)
{
level0.RowStyle.Font.Size = level0.RowStyle.Font.Size+1;
level0.RowStyle.BackColor = Color.WhiteSmoke;

}
if(level1!=null)
level1.ShowHeaders = false;

gridDataBoundGrid1.ExpandAll();

}

Sorry about the wrong grid.

I put your form.Load into the sample.

Exactly what steps do I take to see the problem. The form comes up with the RichtextBox having focus. I can click back and forth between the RTB and the grid without any node collapsing in the grid.

Comment out the line

this.gridDataBoundGrid1.UseListChangedEvent = true;

in the Generator Code.

This has been corrected in version 3.3.
