[CLOSED] How to create and load store to combobox in codebehind

[opendat2000]

Hi,

I need to create and load the sotre to combobox in codebehind. I need to do that, because i have a dynamical formpanel (FP), where FP can have textfield and/or combobox.

This FP can have one of both or many of them, so I need to create and load the store (each store have different data) for each combobox.

So, how I can do that??.

I do this in my code, but the FP don't show me anything.

 private void Create()
        {
                System.Data.DataTable theDataTable = getData(query);
                int cant = int.Parse(theDataTable.Rows.Count.ToString());
                if (cant > 0)
                {                    
                    for (int i = 0; i < cantidad; i++)
                    {
                        System.Data.DataRow theDataRow = getRow();
                        string AtribType = theDataRow["type"].ToString();
                       
                        if (AtribType.Equals(COMBOTYPE))
                        {                            
                            Store str = new Store();
                            str.ID = "Store" + i.ToString();
                            str.Fields.Add(theDataTable.Columns[0].ColumnName);
                            str.Fields.Add(theDataTable.Columns[1].ColumnName, ModelFieldType.String);
                            str.DataSource = theDataTable;
                            str.DataBind();

                            FormPanelAtributos.Items.Add(new ComboBox { FieldLabel = theDataRow["columnA"].ToString(), EnableKeyEvents = true, MsgTarget = MessageTarget.Side, AllowBlank = true, QueryMode = DataLoadMode.Local, StoreID=str.ID, DisplayField = theDataTable.Columns[1].ColumnName, ValueField = theDataTable.Columns[1].ColumnName, EmptyText = "Select...", Name = theDataRow["columnB"].ToString() });
                        }
                        else
                        {
                            FormPanelAtributos.Items.Add(new TextField { FieldLabel = theDataRow["columnA"].ToString(), EnableKeyEvents = true, MsgTarget = MessageTarget.Side, AllowBlank = true });
                        }
                    }
                    FormPanelControls.Render(WindowCtr, RenderMode.AddTo);
                }
}

Best Regards.

Thanks a lot.

Hi @opendat2000,

Do you run that code on initial page load? If so, please remove:

FormPanelControls.Render(WindowCtr, RenderMode.AddTo);

Or during a DirectEvent?

A runnable test case would help us to help you as soon as possible.

Daniil,

thanks for your prompt reply.

No, the code is run when I click on a row in a gridpanel and show the windows with the combobox and/or the textfield.


Example:

1.- Run the app.
2.- Select a item in a treepanel.
3.- Show data in a gridpanel of the item selected in 2.
4.- Click in one of data.
5.- Show the window with a X quantity of combobox and/or textfield.

The window in the point 5 have a different quantity for combobox and/or textfield, this is because that the item selected in the tree panel, are different for others.

Thanks a lot.

Best Regards.

1.- Run the app.

Please clarify - what the app should I run?

[opendat2000]

Run the App is just a example of the step of how works.


thanks a lot.

[Daniil]

Ok. I think I need such an app to go through the steps. Could you, please, provide?
