Questions on UI for WinForms Forum

Hi,
I have encountered some problems:
First, I change my grid's theme to Telerik, at runtime Column Headers's theme still remains unchanged but other parts are effected.
and the user have to hover mouse over the header to see the theme's effect on grid. this happens only one time, at form load.

Second, In a comboobox column the cell doesn't show the correspond value of combobox.

Third, While I have handled DataError, CellValidating, RowValidation Events, why still NoNullAllowedException and DupplicatePrimaryKeyException throws by the application? this happen when I click somewhere on the Form or Grid (this really happens just test it).

Fourth, Do I have to write code to change combobox column' Right To Left property for each Grid of My App?

And more unsolved problems in the near future,
Special thanks to Telerik Team, for lots of time you pay to me.

Parent Child with 2 Grids

Using the gridview controls is there a way to create a parent child relationship and all the grids to handle the table design that they are populated with. For instance if someone adds a row to the parent and that violates the constraints of the table will the grid display that or do I have to handle all of that on my own? When the user changes rows in the parent the child grid should automatically on it's own query the table and repopulate. Is this possible with telerik? My boss thinks the grids should act like the oracle forms or Access forms with the underlying datasource. Will that functionality work with Telerik Winform controls?

Thank You

RadMenu Item can't fully display in Win7

I use RadMenu in my Windows Application. If the application run in WinXP, the text in the menu item can be displayed completely.
However, in Win7, only part of the text is displayed (e.g. only "Men" is displayed instead of "Menu Item"). When the mouse over the menu item, it can be displayed (e.g. "Menu Item").

Is it a bug in Win7 or if there is any setting?

Best Regards,
Emily

radGridView1 CellFormatting problem

Hi everyone,

I'm trying to make a datagrid which allows custom components into cells. I used CellFormatting event of the radGridView. But when i use this event, something strange happening. I introduced the scenario with pictures as bellow;

First i open the form;

Please check 1.png

Then i resize the form;

Please check 2.png

Then i return back to its normal size;

Please check 3.png

Here's the code i wrote for cellformating;

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)

{

if (e.CellElement.ColumnInfo is GridViewDataColumn && ((GridViewDataColumn)e.CellElement.ColumnInfo).Name == "column1")

{

//if (!(e.CellElement.RowElement is GridHeaderRowElement)) // I can't write this code because my codes can't find GridHeaderRowElement class.

{

if (e.CellElement.Children.Count > 0)

return;

ucTextBoxButton txt = new ucTextBoxButton();

txt.KeyDown += new KeyEventHandler(txt_KeyDown);

e.Column.ReadOnly = true;

ucGridViewTextBoxButtonColumn gridviewclm = new ucGridViewTextBoxButtonColumn(txt);

gridviewclm.StretchHorizontally = true;

gridviewclm.StretchVertically = true;

e.CellElement.Children.Add(gridviewclm);

}

Do you have any ideas?

RadGridView Rows.AddNew() problem

Hi everyone,

I'm trying to make a datagrid which allows custom components into cells. But when I call AddNew void, it gives me an error like this;

Constructor on type 'FCS.ManagementConsole.Main.Components.ucTextButtonElement' not found.

Here is my ucGridViewTextButtonCellElement.cs;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Telerik.WinControls.UI;

using Telerik.Reporting.Drawing;

using System.Drawing;

namespace FCS.ManagementConsole.Main.Components

{

class ucGridViewTextButtonCellElement : GridDataCellElement

{

private ucTextButtonElement TextBoxButtonElement;

public ucGridViewTextButtonCellElement(GridViewColumn column, GridRowElement row)

: base(column, row)

{

}

public override void Initialize(GridViewColumn column, GridRowElement row)

{

base.Initialize(column, row);

}

protected override Type ThemeEffectiveType

{

get

{

return typeof(GridDataCellElement);

}

protected override void CreateChildElements()

{

base.CreateChildElements();

TextBoxButtonElement = new ucTextButtonElement();

TextBoxButtonElement.MinSize = new Size(50, 20);

TextBoxButtonElement.Text = "Red";

this.Children.Add(TextBoxButtonElement);

}

Here is my component class;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Telerik.WinControls.UI;

namespace FCS.ManagementConsole.Main.Components

{

class ucTextButtonElement:RadTextBoxElement

{

public event EventHandler ButtonClick;

public ucTextButtonElement()

{

RadButtonElement btn = new RadButtonElement();

btn.Size = new System.Drawing.Size(25, 10);

btn.Click += new EventHandler(btn_Click);

btn.BringToFront();

btn.Text = "...";

}

void btn_Click(object sender, EventArgs e)

{

EventHandler handler = ButtonClick;

if (handler != null) handler(this, e);

}

Here is my ucGridViewTextBoxButtonColumn2.cs;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Telerik.WinControls.UI;

namespace FCS.ManagementConsole.Main.Components

{

class ucGridViewTextBoxButtonColumn2 : GridViewDataColumn

{

public ucGridViewTextBoxButtonColumn2(string fieldName)

: base(fieldName)

{

}

public override Type GetCellType(GridViewRowInfo row)

{

if (row is GridViewDataRowInfo)

{

return typeof(ucTextButtonElement);

}

return base.GetCellType(row);

}

This the code that i get error;

ucGridViewTextBoxButtonColumn2 grid = new ucGridViewTextBoxButtonColumn2("TextBoxColumn");

radGridView1.Columns.Add(grid);

radGridView1.Rows.AddNew();

Do you have any ideas?
