Multicolumngrid Is Inserting an extra subitem and shifting visible data to left.

[Kim Dobranski]

When I first add a node to the multicolumngrid. I am adding 5 SubItems and the subitems.count = 5.

After, if I try to perform any actions on these nodes they now have 6 subitems.  

When I first add a node, SubItem[0]  is the second column in the grid, the first column has the node.text

When I later edit or check the node the node , SubItem[0]  is hidden and the second column in the grid is now SubItem[1] 

Its hard to explain but please see the attached project sample I create to reproduce. 

This is a real problem for me need it addressed ASAP.

Hi Kim,

Thanks for using syncfusion products.

Query 1: When I first add a node, SubItem[0] is the second column in the grid, the first column has the node.text

As per the default behavior of multicolumntreeview the first column will occupy the text of node and following that the subitems are shown. If you want to maintain the node.text in separate column you have add the empty column in your application.

Code Snippet

void FillTree() 

{ 

    multiColumnTreeView1.Columns.Clear(); 

    multiColumnTreeView1.Columns.Add(new TreeColumnAdv() { Width = 125 }); 

    multiColumnTreeView1.Columns.Add(new TreeColumnAdv() { Width = 125, Text = "Column 1" }); 

    multiColumnTreeView1.Columns.Add(new TreeColumnAdv() { Width = 125, Text = "Column 2" }); 

    multiColumnTreeView1.Columns.Add(new TreeColumnAdv() { Width = 125, Text = "Column 3" }); 

    multiColumnTreeView1.Columns.Add(new TreeColumnAdv() { Width = 125, Text = "Column 4" }); 

    multiColumnTreeView1.Columns.Add(new TreeColumnAdv() { Width = 125, Text = "Column 5" }); 

}
