How can I make it so that my datagrid columns span the width of my datagrid, when I get my dataset?

Thanks

this.dataGrid1.SizeChanged += new EventHandler(this.OnSizeChanged);

private void AdjustColumnsWidth()

foreach ( DataGridTextBoxColumn dgtc in this.dataGridTableStyle.GridColumnStyles )
{
dgtc.Width = 80;
}
}

I think that you are miss understanding what I want. I want my datagrid to spread out the columns across the top of the grid depending on the number of tables.

Currently my code is setting a fix size but I cannot even get that working. Do you have any suggestions?

<br />
			GridColumnStylesCollection gcsColl = StudenDataGrid.TableStyles["Student"].GridColumnStyles;<br />
			for (int i = 0; i<gcsColl.Count; i++)<br />
			{<br />
				if (gcsColl[i].GetType() == typeof(DataGridTextBoxColumn))<br />
				{<br />
					DataGridTextBoxColumn textColumn = (DataGridTextBoxColumn)gcsColl[i];<br />
					textColumn.Width = 150;<br />
				}<br />
			}<br />
<br />

Thanks

Hey ,

You want to spread the columns depending on the number of tables or columns? I think I did not understand your question. Assuming you want to spread the columns depending on the number of columns implement AdjustColumnsWidth as. Hope this helps

private void AdjustColumnsWidth()
{
this.isColumnWidthAdjusting = true;
int verticalScrollBarWidth = this.globalEntitySearchGrid.VerticalScrollWidth;
int currentWidth =
this.dataGridTextBoxColumnExConjunction.Width +
this.dataGridTextBoxColumnExEntity.Width +
this.dataGridTextBoxColumnExOperator.Width +
this.dataGridTextBoxColumnExValue.Width +
DELTAFACTOR + this.gridTableStyle.RowHeaderWidth;
int gridClientWith = this.globalEntitySearchGrid.ClientSize.Width - verticalScrollBarWidth;

if (currentWidth > gridClientWith)
{
int delta = currentWidth - gridClientWith;
this.UnWireResizeEvents();
this.dataGridTextBoxColumnExConjunction.Width = this.dataGridTextBoxColumnExConjunction.Width - delta / 4;
this.dataGridTextBoxColumnExEntity.Width = this.dataGridTextBoxColumnExEntity.Width - delta / 4;
this.dataGridTextBoxColumnExOperator.Width = this.dataGridTextBoxColumnExOperator.Width - delta / 4;
this.dataGridTextBoxColumnExValue.Width = this.dataGridTextBoxColumnExValue.Width - delta / 4;
this.RefreshGrid();
this.WireUpResizeEvents();
this.AdjustDynamicControls();
}
else if (currentWidth < gridClientWith)
{
int delta = gridClientWith - currentWidth;
this.UnWireResizeEvents();
this.dataGridTextBoxColumnExConjunction.Width = this.dataGridTextBoxColumnExConjunction.Width + delta / 4;
this.dataGridTextBoxColumnExEntity.Width = this.dataGridTextBoxColumnExEntity.Width + delta / 4;
this.dataGridTextBoxColumnExOperator.Width = this.dataGridTextBoxColumnExOperator.Width + delta / 4;
this.dataGridTextBoxColumnExValue.Width = this.dataGridTextBoxColumnExValue.Width + delta / 4;
this.RefreshGrid();
this.WireUpResizeEvents();
this.AdjustDynamicControls();
}
this.isColumnWidthAdjusting = false;
}

Or this would work too:

			//Put Grid Autosize code here<br />
			DataGridTableStyle style = new DataGridTableStyle();<br />
			style.MappingName = dataTable.TableName;<br />
			foreach (DataColumn column in dataTable.Columns)<br />
			{<br />
				DataGridTextBoxColumn gridColumn = new DataGridTextBoxColumn();<br />
				gridColumn.MappingName = column.ColumnName;<br />
				gridColumn.HeaderText = column.ColumnName;<br />
				gridColumn.Width = StudenDataGrid.Size.Width / accessDataSet.Tables["Student"].Columns.Count;<br />
				style.RowHeadersVisible = false;<br />
				<br />
				style.GridColumnStyles.Add(gridColumn);<br />
			}<br />
<br />
			StudenDataGrid.TableStyles.Add(style);<br />
			this.StudenDataGrid.DataSource = accessDataSet.Tables["Student"];<br />

This will autosize the column headers according to the number of columns you have in your dataset.

Thanks for the help.

WHAT?? If you didn't change anything, there won't be any differences.

Or, like I said, WHAT? I don't understand what your asking. "Difference DLL"???

hi to all,

how can i disable a text box without changing the forecolor to gray.
what i want is to disable the text box and to keep the forecolor to black.

i don't want to use the readonly property because the back color is still white.

best regards and thanks in advance

Those are your only options while still using a TextBox.

A little trick I've seen used before is to create equivilent label controls, set them up to look like the textboxes, and put them behind their textbox counterparts. Then when the textboxes needed to become ReadOnly without the readonly look, they just set the TextBox.Visible property to false.

Hi:

I think this is purely controlled by Windows and may be a little by CLR. I don't think there would be a setting to this effect.

Perhaps yes. But within CLR's realm and through C#, it may not be, since all Memory Management is purely controlled by CLR.

You may need to venture out into direct C++ programming and delve into Windows APIs for that. Is'nt it?

This isn't possible to do in a .NET Framework Managed application.

You'll have to write your app in unmanaged C++ to get this to work.
