Hi,
You could write a javascript for the client-side which checks for a selection of common fonts, and then postback an array of boolean values to the server indicating which of those fonts were found. It is probably best to stick to web-safe fonts.
Hope this is of use!

Set the ViewState property
|
|
|
|
|
Are you adding this control runtime after Page init event ?
if yes add this control in Page Init
if this is static control then make sire that ViewState is enabled of the control and then for the Page.
Thanks and Regards

on form load, i add if (ispostback){combo1.databind()}
|
|
|
|
|
There's your problem. you want to databind when its not a postback, not when it is!
|
|
|
|
|
Put in Page Init method and check if it works
then figure out in Page Load method
Thanks and Regards

Also make sure that your combobox bind when page ispostback property false.
on page load event
if(!IsPostBack)
{
//Bind Combobox here
}

I have noticed that it just not losing the selected value but also writing a blank text. the Viewstates are now enabled and still no change

Can you post your code, it might help us re-create your problem

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
lngSiteID = Convert.ToInt64(Request.QueryString["ID"]);
LoadSiteDetail(lngSiteID);
//loadSiteTreeView();
Session["AddNewRecord"] = "false";
tvwSites.CollapseAllNodes();
tboSiteID.Text = Convert.ToString(lngSiteID);
LoadCombos();
MainContactLoad(lngSiteID);
//LoadData();
}
else
{
lngSiteID = Convert.ToInt64(Request.QueryString["ID"]);
//tboLocation.Text = (string)Session["LocName"];
//LoadSiteDetail(lngSiteID);
//MainContactLoad(lngSiteID);
cboContact.DataBind();
}

}
void check()
{
System.TimeSpan dt_diff = Convert.ToDateTime(to_date).Subtract(Convert.ToDateTime(from_date));
days = dt_diff.Days;
for (int i = 0; i <= days; i++)
{
sql_date = Convert.ToDateTime(from_date).AddDays(i).ToString("MM/dd/yyyy");
sql_date1 = Convert.ToDateTime(from_date).AddDays(i).ToString("MM/dd/yyyy");
dt.Columns.Add(new DataColumn(sql_date1, typeof(string)));
drow = dt.NewRow();
com = new SqlCommand("select * from tbl_report where emp_id='366' and datetime1='" + sql_date + "'", con);
dr = com.ExecuteReader();
while (dr.Read())
{
drow = "x";
dt.Rows.Add(drow);
}
dr.Close();
}
GV_musterrole.DataSource = new DataView(dt);
GV_musterrole.DataBind();
}

This code will blow up for all sorts of reasons. What if a non valid date is entered ?
What you want to do, should be done in the DB, it's called a pivot table.
