hello, everyone:
I am creating a DataGrid form a DataSet with autogeneratecolumns:
dg.DataSource = ds;
dg.DataBind();
But I want to change the style of the columns. Particularly speaking, i want to have all the columns have fixed width/height so that the datagrid may look better. It is because some of the content may have many words. I have tried many methods,however, the datagrid never changed.
Any ideas?
ThanX in advance!

Hi Mini. The code worked as is for me... did you change the datasource or when the data is bound?
The one thing about the technique I demonstrated is that the data must be bound to the grid before the PreRender (or other event of choice) is triggered. If the data isn't bound, then there isn't a child Table control to inspect, and I'm guessing that's why you're getting an error referencing dg.Controls[0].
Another way to go about this, that is probably better anyway, is to use the ItemDataBound event of the DataGrid. Take a look at the event documentation for it on MSDN and you'll see an example of how it is used. It's very similar to the approach I showed here, except that you'll access a table row and its cells through the event args that are passed to the ItemDataBound event handler, rather than accessing the child Table control directly.
If there's interest, I might be able to work up an article on this fairly quickly.

Thank u, Mike and miniThomas, for the attention.
I have tried both of the approach, however, the datagrid is still not changed. I am wondering if it is beacause the width of the datagrid could not be longer than certain value, for some of the columns are really quite long. looking forward to ur further answer.
Regards,
Steven

Hi Steven. I do think you'll want to trap ItemDataBound in your datagrid. You can Google "ItemDataBound" for examples.
I've submitted an article about this topic that will hopefully get posted soon that also shows an example.

Hi All
I have a datagrid & I want it to be sorted when the user clicks on the column header..How can I do that??
Thanks a lot in advance
Happy

it's very simple
use this function in your class file or at code behind
public void BindGrid(DataTable dt, DataGrid dg, string sortexpression, string order)
{
try
{
if (dt.Rows.Count > 0)
{
DataView dv;
dv = dt.DefaultView;
if (sortexpression != "")
{
if (order == "desc")
dv.Sort = sortexpression + " DESC";
else
dv.Sort = sortexpression;
}
dg.DataSource = dv;
dg.DataBind();
}
}
catch (Exception ex)
{
clsLog.WriteLog(ex.Message);
throw ex;
}
}
where, argument1=datatable object where you hv stored the data which you would like to display
2.argument2=your datagrid id
3.argument3=variable(here u cn take sortexpression which you will declare at the beginning like this private string sortexpression = "";)
4.argument4= Convert.ToString(ViewState["order"])
now on click of column_header event write the code
LinkButton lnkbtn;
lnkbtn = (LinkButton)sender;
if (Convert.ToString(ViewState["order"]) == "Asc")
{
ViewState["order"] = "desc";
}
else
{
ViewState["order"] = "Asc";
}
if (lnkbtn.Text == "1st column headername")
{
sortexpression = "1st column headername";
}
if (lnkbtn.Text == "2ndcolumn headername")
{
sortexpression = "2ndcolumn headername";
}
fillgrid();
(i think u know what to write in this function here just bind ur grid and one more thing in this function call the sort function with required paramts mentioned above)

Change the allowSorting datagrid property to true
go to Columns property, select the field what you want to sort, write onto the SortExpression the same column datafield.
On datagrid sorting function
<br />
protected void Grid_Sorting(object sender, GridViewSortEventArgs e)<br />
{<br />
string sql = "SELECT * FROM table WHERE conditions ORDER BY " + e.SortExpression;<br />
SqlDataAdapter data_Adapter = new SqlDataAdapter(sql, conexxxion);<br />
DataSet dataSet = new DataSet();<br />
data_Adapter.Fill(dataSet);<br />
Grid.DataSource = dataSet.Tables[0].DefaultView;<br />
Grid.DataBind();<br />
}<br />
you can do it with all datagrid columns

The simple answer is 'You can not'. The only FileOpen dialog you get is 'Browse' using , which creates a textbox and a button. Anything else might need ActiveX.
