Column width on datagrid

Hi,

You can give them the style you want, manipulate it as much as you can by setting the header  style

Do it for the column that you think it might be applied.

<Columns>
            <asp:CommandField ShowSelectButton="True" />
                <asp:BoundField DataField="MyType" HeaderText="MyType" SortExpression="MyType" >
		     <HeaderStyle Width="100px"/>
		 <asp:BoundField>    
               .....
</Columns>

Well, I think I misunderstood your question, you wanted to set the width of the TextBox appropriately to the Width of the column??

You will have to do it in RowDataBound event of the gridView, is that you want the textBOx inside your grid or outside? you can get in there, count column
e.Row.Cells.Count

 and on each colum you get the width of that column:
int colWidth = e.Row.Cells[index].Width

Then you find your textBox control by:
TextBox myTB = e.Row.Cells[3].FindControl("tbTextBoxID")
myTB.width = colWidth


Hope it gives you some idea

protected void gvShaders_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //.... depend on how you want to put your textbox more condition will be added and changed
        if (e.Row.RowType == System.Web.UI.WebControls.DataControlRowType.DataRow)
        {
	        /...another tracking to find row of the textBox
		 //and on each colum you get the width of that column:
		int colWidth = e.Row.Cells[index].Width
 
		//Then you find your textBox control by:
		TextBox myTB = e.Row.Cells[3].FindControl("tbTextBoxID")
		myTB.width = colWidth	
        }
}

I would be looking to have the textbox outside the Gridview. I will look at your solutions now.

ok then you dont have to user RowDataBound, do you know in advance how many textbox you have or you create it after the GV is binded

If so, you need a placeHolder: just play around to get the layout right the way you want it
for(int i = 0; i < myGV.Columns.Count; i++)
{
   int colWidth = myGV.Columns[i].ItemStyle.Width
   TextBox myTextBox = new TextBox();
   myTextBox.Width = colWidth;
   plhBoxes.Add(myTextBox);
}

I know how many I have in advance. How can I set the size of the textbox based on their ID.

ok, as I posted.

for example if you have this textBox
<asp:TextBox ID="tbSearchName" runat="server"/>

And the Colum: "CusName" is at index 2;
then after the gridView binding in your .cs file:
tbSearchName.Width = "200px";
or bSearchName.Width = gvShaders.Columns[1].ItemStyle.Width;

// you might wanna check the casting, it's Unit type so just play around with it

My column 1 would have corresponding textbox myTextbox1,
column 2 would have corresponding textbox myTextbox2, etc etc..

myTextbox1.Width = mygv.Columns[1].ItemStyle.Width;

JINN

That doesnt seem to work for me now.

Im actually thinking of now trying to have the textboxes inside my grid. Is that what you have above?

WHere do you put this?
myTextbox1.Width = mygv.Columns[1].ItemStyle.Width;

You have to make sure you set this after the GirdView has already been binded. If you want to put the boxes inside the gridView, it's different story, quite tricky I assume (because you only want 1 box for each column)

I put it like below and as i step through it, colWidth  = 0 all the time..

Any ideas?

protected void LabourCostsGrid_DataBound(object sender, EventArgs e)
        {
            for(int i = 0; i < LabourCostsGrid.Columns.Count; i++)
            {
                double colWidth = LabourCostsGrid.Columns[i].ItemStyle.Width.Value;
            }
 
        }
