Set Row Header

[stewart]

Prior to using RadGridView, i made use of the new DataGridView in .NET 2.0.

consider the code below, where i successfully populate the row headers:

string[] userInputParams = new string[] {"apples","oranges",
                                                              "mangos",
                                                              "guanábana"}
 for (int i = 0; i < userInputParams.Length; i++)
 {
                gridRows.Add();
                gridRows[i].HeaderCell.Value = userInputParams[i];
}

How would i acheive this with the telerik RadGridView winform control?

thank you

Hi stewart,

Thank you for writing us.

In RadGridView you achieve this behavior by using the HeaderText property of the GridViewColumn. Consider the following code snippet:

this.radGridView1.DataSource = table;
this.radGridView1.Columns[0].HeaderText = "apples";
this.radGridView1.Columns[1].HeaderText = "oranges";
this.radGridView1.Columns[2].HeaderText = "mangos";
this.radGridView1.Columns[3].HeaderText = "guanábana";

Let us know if you have any other questions.

Hi Jack,

Thank you for your quick reply.  The code you supplied will
set the column headers, while my code, if you notice, is accessing
the HeaderText property for individual gridRows (a row collection)
items.  The end goal is to set the row header.

i have been unable to reference the row header directly.
I  tried using the GridRowHeaderCellElement constructor,
with no success.

I've resorted to a solution that employs the radGridView1_RowFormatting
event as per the forum posting: http://www.telerik.com/community/forums/thread/b311D-heamc.aspx

I am using the trial version of 'RadControls for WinForms Q3 2007 SP1',
is there an updated release, perhaps a Q1 2008?  I am very interested
in your product, and would like to incorporate it into our solutions.

once again,

thank you,

Hello Stewart,

I apologise as I didn't understand your question the first time. You can access the row header cell by processing the CellFormatting event. Consider the code snippet below:

this.radGridView1.CellFormatting += new CellFormattingEventHandler(radGridView1_CellFormatting);
void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement is GridRowHeaderCellElement)
    {
        e.CellElement.BackColor = Color.Red;
        e.CellElement.DrawFill = true;
    }
}

Don't hesitate to write us if you have other questions.

Hi Jack,

I'm using RadGridView WinForms, I want to show row numbers in row header similar to row numbers shown in excel. Apart from cell formatting event code you shared in your previous thread is there any syntax to explicitly set row as row header? Please help with syntax how to set row header after radGridView1.Rows.AddNew(); 

Thanks in advance.

Hi Kalpana,

There is no dedicated row number column in RadGridView. The best way to do this is by handling the CellFormatting event. Consider the sample below:

this.radGridView1.CellFormatting += new CellFormattingEventHandler(radGridView1_CellFormatting);
this.radGridView1.Columns.Insert(0, new GridViewTextBoxColumn("RowHeader") { ReadOnly = true, HeaderText = " " } );

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
    GridDataCellElement cell = e.CellElement as GridDataCellElement;
    if (cell.ColumnInfo.Name == "RowHeader")
    {
        cell.Text = cell.RowInfo.Index.ToString();
    }
}

I hope it helps.
