All the state name values are "select". So the code may be checking if the value is not "select" accept the value. Please try it out with this logic

Make sure that the scriptmanager is the first thing (ajax at least) on your page - it must be found before the calandarextension tag...

Hi,
I have a question. I have a gridview in my aspx page. I grabed the data from table. But I want that when I see the aspx page initialy the gridview should be sorted by a column name FirstName in asscending order by default. How can I do that.
Thanks
|
|
|
|
|
In your query that is the data in the table if it is sql you can do
order by FirstName asc
You can also do sorting if you are binding to the datatable directly. Switch to using a DataView and set the sort Property on the dataview.
Something like
DataView dv = yourdataTable.DefaultView;
dv.Sort = "FirstName";
gridview.DataSource = dv;
gridview.DataBind;
Hope that helps.

hi,
I have a web page and it has three textboxes. It has already some text. When I edit the text boxes and click on Edit button the button supposed to epdate the data in the database. But when I debug it the value of textboxes gives me the previous value not the edited value may be in postback it lost it's new value. I set enableviewstate property to True but even then it doesn't work.
Thanks in advance.

If you are setting the textbox text in the form load event you need to make sure you have a check on the IsPostBack property. The page load event happens before your edit event, so the data gets set back to its original value in the page load. So you need some code like this:
If (!IsPostBack)
{
textBox.Text = "somevalue";
}
or
If Not IsPostBack Then
textBox.Text = "somevalue
End If
Hope that helps.

I have the following code but when I build this it gives me errors that username, userpass, userfname does not exist in current context.
I don't know where is the problem and how can I fix this.
SqlConnection objConn = new SqlConnection("Data Source=sql1300.mssqlservers.com;Initial Catalog=twcsan;Persist Security Info=True;User ID=twcsan;Password=mln0531");
SqlCommand objCmd = new SqlCommand("UPDATE tbUsers SET MyName = @username, " +
"MyPass = @userPass, " +
"UserFName = @userfname, " +
"WHERE UserId = 10", objConn);
objConn.Open();
objCmd.Parameters.AddWithValue(@username1, TextBox1.Text);
objCmd.Parameters.AddWithValue(@userPass, this.TextBox2.Text);
objCmd.Parameters.AddWithValue(@userfname, this.TextBox3.Text);
objCmd.ExecuteNonQuery();
objConn.Close();
Thanks in advance

Please try to write a relevant subject. "urgent please help" says nothing about your specific question, and does nothing to distinguish it from all the other questions.
You have forgotten the quotes around the strings.
objCmd.Parameters.AddWithValue("@username1", TextBox1.Text);

Hi all,
I have a gridview that has an edit template with a textbox and a dropdown list in it.
At runtime the textbox and dropdown are invisible on the gridview (because they only show in edit view).
When I click "Edit", the textbox and dropdown appear.
I want to be able to reference the dropdown list but when I try to do so, I get the "Object reference not set to an instance of an object." error.
Here is my code:
protected void grdTrak_RowDataBound1(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
((DropDownList)e.Row.FindControl("dlStatus")).Attr ibutes.Add("onSelectedIndexChanged", "enableother(this)");
}
}
Does any one know what the problem could be?
Thank you in advance!
Dave

The row data bound happens for every row in the gridview. Only one row is set in edit mode, so you can not assume you will find the dropdown in each of the rows as they get data bound.
Hope that helps.
