Hidden property for column in child row doesn't work ( Hierarchical ultrawingrid , ultragrid, wingrid )
posted

It looks like the hidden propery deosn't work in the Hierarchical ultraGrid for the child rows.

I create a simple form with one UltraGrid in it and I manually put 2 bands in it and in the page load I put the code below.

 private void HiddenColumns_Load(object sender, EventArgs e)

{ 

 

 

//======================================

//step 1: ultrawingrid structure

ultraGrid1.DisplayLayout.Bands[0].Columns.Add("Primary");

ultraGrid1.DisplayLayout.Bands[0].Columns.Add(

"parentcol");

ultraGrid1.DisplayLayout.Bands[0].Columns.Add(

"parenthidden");

ultraGrid1.DisplayLayout.Bands[0].Columns[

"parenthidden"].Hidden = true;

ultraGrid1.DisplayLayout.Bands[1].Columns.Add(

"Foreign");

ultraGrid1.DisplayLayout.Bands[1].Columns.Add(

"ChildPrimary");

ultraGrid1.DisplayLayout.Bands[1].Columns.Add(

"childhidden");

ultraGrid1.DisplayLayout.Bands[1].Columns[

"childhidden"].Hidden= true;

 

 

 

 

 

 

 

 //======================================

 

 

//step 2: Dataset structure

 DataSet ds = new DataSet();

ds.Tables.Add(

"Parent");

ds.Tables.Add(

"Child");

ds.Tables[

"Parent"].Columns.Add("Primary");

ds.Tables[

"Parent"].Columns.Add("parentcol");

ds.Tables[

"Parent"].Columns.Add("parenthidden");

ds.Tables[

"Child"].Columns.Add("Foreign");

ds.Tables[

"Child"].Columns.Add("ChildPrimary");

ds.Tables[

"Child"].Columns.Add("childhidden");

ds.Tables[

"Parent"].PrimaryKey = new DataColumn[] { ds.Tables["Parent"].Columns["Primary"] };

ds.Tables[

"Child"].PrimaryKey = new DataColumn[] { ds.Tables["Child"].Columns["ChildPrimary"] };

ds.Relations.Add(

"relation",ds.Tables["Parent"].Columns["Primary"],ds.Tables["Child"].Columns["Foreign"]);

 

//======================================

 

 

 

 

 

 

 

 

 

 

 

 

 

 

//step 3: adding rows to the dataset

 DataRow rowParent = ds.Tables["Parent"].NewRow();

rowParent[

"Primary"] = 1;

rowParent[

"parentcol"] = "Hello!!!";

rowParent[

"parenthidden"] = "I am hidden in parent";

ds.Tables[

"Parent"].Rows.InsertAt(rowParent, 0);

 

DataRow rowrChild = ds.Tables["Child"].NewRow();

rowrChild[

"Foreign"] = 1;

rowrChild[

"ChildPrimary"] = 101;

rowrChild[

"childhidden"] = "I am hidden in child";

ds.Tables[

"Child"].Rows.InsertAt(rowrChild, 0);

 

//======================================

 

 

 

 

 

 

 

 

 

 

 

 

//step 4: binding the dataset to the grid

ultraGrid1.DataSource = ds;

}

 

this is the result I was expecting the childhidden to be hidden just like the parenthidden that's hidden in the parent row.

 please I am stuck with this problem, I need and explanation.

thanks for all your help in advance.

    the code was formated automatically when I posted so here is a better version of it.

    private void HiddenColumns_Load(object sender, EventArgs e)

            {

                //======================================

                //step 1: ultrawingrid structure

                ultraGrid1.DisplayLayout.Bands[0].Columns.Add("Primary");

                ultraGrid1.DisplayLayout.Bands[0].Columns.Add("parentcol");

                ultraGrid1.DisplayLayout.Bands[0].Columns.Add("parenthidden");

                ultraGrid1.DisplayLayout.Bands[0].Columns["parenthidden"].Hidden = true;

     

                ultraGrid1.DisplayLayout.Bands[1].Columns.Add("Foreign");

                ultraGrid1.DisplayLayout.Bands[1].Columns.Add("ChildPrimary");

                ultraGrid1.DisplayLayout.Bands[1].Columns.Add("childhidden");

                ultraGrid1.DisplayLayout.Bands[1].Columns["childhidden"].Hidden= true;

     

                //======================================

                //step 2: Dataset structure

                DataSet ds = new DataSet();

                ds.Tables.Add("Parent");

                ds.Tables.Add("Child");

     

                ds.Tables["Parent"].Columns.Add("Primary");

                ds.Tables["Parent"].Columns.Add("parentcol");

                ds.Tables["Parent"].Columns.Add("parenthidden");

     

                ds.Tables["Child"].Columns.Add("Foreign");

                ds.Tables["Child"].Columns.Add("ChildPrimary");

                ds.Tables["Child"].Columns.Add("childhidden");

     

                ds.Tables["Parent"].PrimaryKey = new DataColumn[] { ds.Tables["Parent"].Columns["Primary"] };

                ds.Tables["Child"].PrimaryKey = new DataColumn[] { ds.Tables["Child"].Columns["ChildPrimary"] };

     

                ds.Relations.Add("relation",

                        ds.Tables["Parent"].Columns["Primary"],

                        ds.Tables["Child"].Columns["Foreign"]);

     

                //======================================

                //step 3: adding rows to the dataset

                DataRow rowParent = ds.Tables["Parent"].NewRow();

                rowParent["Primary"] = 1;

                rowParent["parentcol"] = "Hello!!!";

                rowParent["parenthidden"] = "I am hidden in parent";

                ds.Tables["Parent"].Rows.InsertAt(rowParent, 0);

     

                DataRow rowrChild = ds.Tables["Child"].NewRow();

                rowrChild["Foreign"] = 1;

                rowrChild["ChildPrimary"] = 101;

                rowrChild["childhidden"] = "I am hidden in child";

                ds.Tables["Child"].Rows.InsertAt(rowrChild, 0);

     

     

                //======================================

                //step 4: binding the dataset to the grid

                ultraGrid1.DataSource = ds;

     

            }
