Hi,

I'm Using radGridView to load data from Datatable;

DataTable is populated from the Database;

2 Columns are added at design time;

If i Use radGridView1.AutoGenerateColumns = true;

then it shows 4 Columns on populating data.

and if i Use radGridView1.AutoGenerateColumns = false;

Hi

I have a data grid and I am wondering if the column header text can be vertical ? If so, how do you make the text vertical?

Within the grid I have columns with Y and N, I want to make the background of the cell Green if Y and Red if N - what do I need to do to achieve this?

In this update the Breadcrumb got several updates.

One of the updates is the text editing mechanism, but for my application, this is an unwanted option. How can I disable this option?

TextBoxColumn - MultiLine, Wrap Text, Vertical Size

Can you make a row autosize or otherwise set the height so that all of the the text in the cell in a TextBoxColumn is visible? For some of the rows, the text string is short. For others, it will take four lines to contain the text.

Thank you,
Gary

Hi,

I want to remove the top four buttons from Image Editor control. How can do I do that? I found one thread for "UI for WPF", but the properties mentioned in that thread, like IsOpenButtonVisible etc are not there in my latest downloaded version of control.

Thanks!

public class CustomCellElement : GridDataCellElement

{

private RadButtonElement radButtonElement;

private RadButtonElement radButtonElement1;

private RadTextBoxElement radTextBoxElement;

public CustomCellElement(GridViewColumn column, GridRowElement row) : base(column, row)

{

}

protected override void CreateChildElements()

{

base.CreateChildElements();

radButtonElement = new RadButtonElement

{

Text = "-",

Margin = new Padding(1, 1, 2, 1)

};

radButtonElement.Click += new EventHandler(radButtonElement_Click);

this.Children.Add(radButtonElement);

this.radTextBoxElement = new RadTextBoxElement

{

Margin = new Padding(1, 1, 1, 1),

TextAlign = HorizontalAlignment.Right

};

this.Children.Add(radTextBoxElement);

radButtonElement1 = new RadButtonElement

{

Text = "+",

Margin = new Padding(2, 1, 1, 1)

};

radButtonElement1.Click += new EventHandler(radButtonElement1_Click);

this.Children.Add(radButtonElement1);

}

private void radButtonElement_Click(object sender, EventArgs e)

{

int value = Convert.ToInt32(radTextBoxElement.Text) - 1;

if (value > 0)

radTextBoxElement.Text = Convert.ToString(value);

}

private void radButtonElement1_Click(object sender, EventArgs e)

{

int value = Convert.ToInt32(radTextBoxElement.Text) + 1;

if (value > 0)

radTextBoxElement.Text = Convert.ToString(value);

}

protected override void DisposeManagedResources()

base.DisposeManagedResources();

}

}

protected override SizeF ArrangeOverride(SizeF finalSize)

{

if (this.Children.Count == 3)

{

float textBoxWidth = finalSize.Width - radButtonElement.DesiredSize.Width - radButtonElement1.DesiredSize.Width;

RectangleF buttonRect = new RectangleF(0, 0, radButtonElement.DesiredSize.Width, finalSize.Height);

RectangleF textBoxRect = new RectangleF(radButtonElement.DesiredSize.Width - 1, 0, textBoxWidth - 1, finalSize.Height);

RectangleF button1Rect = new

RectangleF(textBoxWidth + radButtonElement.DesiredSize.Width - 1, 0, radButtonElement1.DesiredSize.Width, finalSize.Height);

this.Children[0].Arrange(buttonRect);

this.Children[1].Arrange(textBoxRect);

this.Children[2].Arrange(button1Rect);

}

return finalSize;

}

{

public CustomColumn() : base()

{ }

public CustomColumn(string fieldName) : base(fieldName)

}

public CustomColumn(string uniqueName, string fieldName) : base(uniqueName, fieldName)

{

}

public override Type GetCellType(GridViewRowInfo row)

{

if (row is GridViewDataRowInfo)

{

}

and How a Add it GridView

CustomColumn customColumn = new CustomColumn

{

Name = "Qty",

FieldName = "Qty",

HeaderText = "Quantity",

Width = 150,

HeaderTextAlignment = ContentAlignment.MiddleRight,

TextAlignment = ContentAlignment.MiddleRight

};

radGridView1.MasterTemplate.Columns.Add(customColumn);

I'm Facing Display problem Please see Image.

Buttons are not displaying properly, cutting the sides. TextBox should be according to the height of GridView cell you can see empty area at the bottom.

How to get and set the value of text box. when row is adding directly to grid.

Please note that the Gridview AllowAddNewRow & AllowEditRow is set to False.(adding Row to GridView Programatically)

But I can Still change the value in the Textbox(Editing to textbox should be disabled.)

Apply the format like other column(please see image).

Thank you
