Hi,
I have written an user control (UserControl) and i would like to allow only one instance per page to be instantiate by its type.
Do you know what is the best method to achieve this? It has to work in both the statical and dynamical loading scenarios.

I worked on a server that had the same problem. To get the validators to work, I have to turn off client side validation. Then they worked.

Hi,
I am developing a web appication using asp.net with c#.
I am updating Dataset using datgrid EditItemTemplate and storing in cache.
finally i want to update my table using SqlAdaptor Update mathod but i am gatting error.Please help me..
This is my Dataset Update mathod:
public void grdEmployee_Update(Object o,DataGridCommandEventArgs e)
{
int id = (int)grdEmployee.DataKeys[e.Item.ItemIndex];
TextBox txtName,txtDesignation,txtSex,txtAge,txtSalary;
txtName =(TextBox)e.Item.Cells[0].Controls[0];
txtDesignation =(TextBox)e.Item.Cells[1].Controls[0];
txtSex =(TextBox)e.Item.Cells[2].Controls[0];
txtAge =(TextBox)e.Item.Cells[3].Controls[0];
txtSalary =(TextBox)e.Item.Cells[4].Controls[0];
if (Cache["EMPCACHE"]!=null)
{
DataSet dsUpdate= (DataSet)Cache["EMPCACHE"];
dsUpdate.Tables[0].Rows[e.Item.ItemIndex]["NAME"]=txtName.Text;
dsUpdate.Tables[0].Rows[e.Item.ItemIndex]["DESIGNATION"]=txtDesignation.Text;
dsUpdate.Tables[0].Rows[e.Item.ItemIndex]["SEX"]=txtSex.Text;
dsUpdate.Tables[0].Rows[e.Item.ItemIndex]["AGE"]=Convert.ToInt32(txtAge.Text);
dsUpdate.Tables[0].Rows[e.Item.ItemIndex]["SALARY"]=Convert.ToSingle(txtSalary.Text);
dsUpdate.AcceptChanges();
Cache["EMPCACHE"]=dsUpdate;
grdEmployee.EditItemIndex = -1 ;
grdEmployee.DataSource = dsUpdate;
grdEmployee.DataBind();
}}
Finally i am going to update on Database using this code
private void btnDatabaseUpdate_Click(object sender, System.EventArgs e)
{
try
{
string strConnection= System.Configuration.ConfigurationSettings.AppSettings.Get("ConnectionString");
SqlConnection con = new SqlConnection();
con.ConnectionString = strConnection;
SqlDataAdapter sda = new SqlDataAdapter("select ID,NAME,DESIGNATION,SEX,AGE,SALARY from EMPLOYEEDETAILS",con);
SqlCommandBuilder scb = new SqlCommandBuilder(sda);
sda.Fill(dsObj,"EMPLOYEEDETAILS");
DataSet dsUpdate = (DataSet)Cache["EMPCACHE"];
dsObj = dsUpdate.Copy();
int success=sda.Update(dsObj,"EMPLOYEEDETAILS");
dsObj.AcceptChanges();
grdEmployee.DataSource = dsObj;
grdEmployee.DataBind();
}
catch (Exception ex)
{
Response.Write("
" + ex.Message.ToString());
}
}
I am gatting this error:
Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.

Check your sqlDataSource object... first make sure the connection string you are using supports update operation. Second, when you get to the screen where it asks you to type in the SQL statements, click on the Advanced button, then check "Generate Insert, Update, and Delete statements" box. You may also check the "Optimistic concurrency" box as well.
If the above doesn't help you, Zip your project, and email it to me so I can take a look at it  NightHawk13@hotmail.com

To get the selected Text from the dropdownlist
TextBox2.Text = DropDownList1.SelectedItem.Text;
To get the selected Value from the dropdownlist
TextBox2.Text = DropDownList1.SelectedValue;
(or)
TextBox2.Text = DropDownList1.SelectedItem.Value;

thnx Deepa,,
Through collection its 100% possible..The basic problem is there tht the event (DropDownList2_SelectedIndexChanged)is not fired on ..so the problem is arising..
else the associated code is absolutly running fine(TextBox2.Text = DropDownList2.Text;
TextBox2.Text = DropDownList1.SelectedValue;).
Both statments r crect
Regards
shriya

Make the autopostback event property of the dropdownlist to true..
Have you placed the dropdownlist on the form or in a panel??
where there is a will there is a way
