Hi
I have to populate some datas from sql server database and display it directly in a CSV Format or CSV file. When i run the project it should provide me an option to whether open or save or cancel the file. when i click open it should be opened and be viewed in a excel sheet in CSV format and when i click save it should ask the destination folder and should be saved there in CSV format and when i click cancel it should be cancelled and the application should be closed. pls note that all these actions should happen in the same browser and should not be redirected to anyother page. Can anybody give me the detailed description and code in Asp.Net using C# .It's very Urgent.
Regards
Vijay.

Not only are you impatient, asking this multiple times in the same forum, you also feel it's urgent enough to spam other forums.

HI All,
I have a page in which there is a check box control. When this check box is checked then another page is loaded to an IFRAM. There is a Button in IFRAM page named Back. I want when I click on Back the Check box should be unchecked. Problem is that Check box is on Parent Page and that Button is on IFRAM page. How can I do that i-e when some one click on IFRAM page Back Button the Parent Page Check box should be Unchecked.
Please Help me
Thankx in Advance.

You've asked this question many times, and have been given viable solutions. Maybe your practice of using IFRAMEs is the problem.

Hey Palani,
There might be the following scenarios,
1) you COM Component is not registered in the webserver,
search your registry for "D07EDCC5-4AB7-4B40-91AB-C5BAEE7FA608"
user regsvr32 command
2) your COM might not be binary compatible , may be u built it again and it changed its class id (happens with VB COM if u dont select binary compatibility)
3)The "Logged On User" -- usually the anonymous account -- does not have adequate permissions to run the control. In many cases the anonymous login account (IUSR_<machine>) does not have appropriate permissions on certain Directories/Files or the specific component and its dependencies. While less frequent, if the registry permissions for certain keys are not set correctly, it causes the control to fail to initialize
4)The "Everyone" group has been removed from having READ permissions on certain registry keys due to the mistaken notion that Everyone means ANYONE, when in actuality it simply means all validated users on the Domain/machine.

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.
waiting for promp reply

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;
