DataSet, GridView DataBinding to Parent Information

Hi,

I have setup a dataSet with 3 tables Locations,Customers and Orders. I have setup 3 relations "Locations to Customers" , "Locations to Orders" and "Customers to Orders"

I have a form that has two GridViews one to show All the Customers and one to show the Selected Customers Orders.

I have done this by:

MainForm.DataSource = FormData;

MainForm.DataMember = "Customers";

SubForm.DataSource = FormData;

SubForm.DataMember = "Customers.Customers_Orders";

Is there anyway I can bind a column to the Locations Description from the Locations table via the "Locations to Customers"/"Locations to Orders" in the relative grids?

Dropdown Multi-line Textbox

I am a new(will be official by the end of the week) Telerik customer that is migrating from DevExpress. I have, obviously, been impressed so far but I have come across a concern. My app makes extensive use of DevEx's "Dropdown Multiline Textbox control and I have not seen a similar control for Telerik so far. Am I missing it or would I have to create it myself by embedding the Textbox into a Dropdown control? If so is there any guidance on that?

While this isn't a deal breaker it will be a bit of a downer if the first thing I have to do after purchasing a $1300 Custom Control suite is build my own custom control....

Thanks for any help and direction that can be provided.

Binding Dataset with Filter causes Problems

Hi,

In the code below I have a dataset connected to a radTreeView. It is recursive and it works. When I try to filter the dataset with the .Select command the radTreeView knows there is data there but the displaymember stays blank - meaning no text in the tree. Why?

Thanks,
Karl

private void BindLangDataToTree()

{

this.radTreeView1.DisplayMember = "Thema_" + myLang; ;

this.radTreeView1.ParentMember = "pid";

this.radTreeView1.ChildMember = "id";

this.radTreeView1.ValueMember = "id";

radTreeView1.DataSource = ds_Baum.Tables["Baum"];//.Select("Schule='" + mySchuleID + "'");

}

[Solved] GridViewComboBoxColumn DBNull issue

Hi,

I have a ComboBoxColumn that is bound to a datatable. One of the options in the datatable is "None" with a value of DBNull. I have the DisplayMember and ValueMember set and everything works just fine, except when I choose "None" in the list and move off the row. The column with the ComboBox is empty instead of "None". Any other value displays the lookup text just fine.

Any ideas?

RadGridView initialization delay

Hi,
Could I make RadGridView control's initialization faster? Currently first initialization of this control can take few seconds, what is quite long in case of dialog window, appearing on demand.

Sample code:

public partial class RadGridViewDialog : Form

{

private RadGridView _grid;

public RadGridViewDialog()

{

InitializeComponent();

}

private void btnInitialize_Click(object sender, EventArgs e)

{

_grid = new RadGridView();

panel2.Controls.Add(_grid);

_grid.Dock = DockStyle.Fill;

_grid.BringToFront();

}

private void btnBuild_Click(object sender, EventArgs e)

{

using (_grid.DeferRefresh())

{

GridViewDataColumn firstColumn = new GridViewTextBoxColumn();

firstColumn.HeaderText = "Name";

_grid.Columns.Add(firstColumn);

firstColumn.ReadOnly = true;

GridViewDataRowInfo[] rows = new GridViewDataRowInfo[200];

GridViewDataColumn secondColumn = new GridViewTextBoxColumn();

secondColumn.HeaderText = "Value";

_grid.Columns.Add(secondColumn);

secondColumn.Width = 110;

secondColumn.MinWidth = 70;

int rowIndex = 0;

for (int i = 0; i < rows.Length; i++)

{

rows[rowIndex] = new GridViewDataRowInfo(_grid.MasterView);

rows[rowIndex].Cells[0].Value = "name" + i;

rows[rowIndex].Cells[1].Value = "value" + i;

rowIndex++;

}

firstColumn.IsPinned = true;

_grid.Rows.AddRange(rows);

firstColumn.BestFit();

}

After first opening this form, when user clicks on btnInitialize button application is freezing for few seconds, clicking on btnBuild button is much faster. Second and next clicks on btnInitialize (no matter in the same or other dialog in the same application) are faster too.

I've noticed that it's a reason of calling:
Telerik.WinControls.Themes.ControlDefault.ExternalControlsThemeHelper.LoadGridThemes()
in the static constructor of class Telerik.WinControls.UI.RadGridViewElement.

Is it possible to speed up first initialization of this class?

Regards

GridView
