I want to display a gridview when a textbox is focused. The gridview is hidden when the page is loaded and as soon as the focus is on the textbox the gridview should be visible.
Here is my code
<asp:TextBox CssClass="txt" ID="txtEducation1" AutoPostBack="true" runat="server" onfocus="MyFunction"></asp:TextBox>
protected void MyFunction(object sender, EventArgs e)
{
gridview1.Visible = true;
}

What I need to do Is constantly read the cpu percentage and display it to a textbox, but the issue is I am using the windows form not the console so I cant use a while loop. I think my best bet is to use an event, but I am not sure how.

I have question regarding Gridview.
Can i set each column in Gridview with different Datasource ? for example I create Gridview with 3 column , can I set each column with different datasource ?
I have two tables
Orders
ID, CreatedDate,CustomerID
1, 03/04/2014, test
OrderDetails
ID,ProductId, ProductName,Quantity,Price,Total
1, 5, Toy, 5, 1.99, 9.95
I have a gridview, im using its 'datasource dropdownlist' to populate it, i have the SQL statement
SELECT Orders.ID, OrderDetails.ProductId, OrderDetails.ProductName, OrderDetails.Quantity, OrderDetails.Price, OrderDetails.Total FROM (OrderDetails INNER JOIN Orders ON OrderDetails.ID = Orders.ID) WHERE (Orders.CustomerId = ?)
where the '?' is parameters source = QueryString, and QueryStringField= email
i have a session that is the customerEmailId, so
string CustomerEmailID = (string)Session["email"];
Response.Redirect("MyAccount.aspx?email=" + CustomerEmailID);//i have tested it and customerEmailid is test
however nothing loads in the GridView
I can enter text in the first cell but it disappears when I move to the next cell. What can be causing this to happen? I using C#, DevExpress Winforms.

I am having a problem with deleting gridview rows. I am populating my gridview by selecting value in a dropdownlist then by clicking the add button, value will be added in my gridview, here is my code:
In my aspx:
<asp:GridView ID="GridView1" runat="server"
CssClass="mGrid" EmptyDataText = "There are no records to display">
<Columns>
<asp:TemplateField ItemStyle-Width="10">
<HeaderTemplate>

With the btnRemove codes above, If I clicked it, it'll remove all values in my gridview even the unchecked rows, what I want is that just the checked rows not all. And are there any other simple way of removing rows in a gridview than using checkbox? I am using c# with asp.net.
I have a gridview in which I show report data, I wanted to print this data, so I added print functionality. This print functionality does not print entire gridview data, it only prints data which is visible on the screen and skip the data which is under vertical scroll bar.
Below is the print grid view code in c# for WINDOWS APPLICATION.
private void btnPrint_Click(object sender, EventArgs e)
{
if (printDialog1.ShowDialog() == DialogResult.OK)

passing selected row in gridview to my dropdown. I have 1 gridview, 1 textbox and 1 dropdown list box. My dropdown is populated by SqlDataSource from my table Country. On my gridview, I have 3 columns, which are SELECT, NAME and COUNTRY. Under SELECT column, I have my hyperlinked Select, every time I clicked on a certain row NAME will pass in textbox (no problem with that), but in my dropdown it does not populates the COUNTRY that I choose. For example, I have Jack for name and USA for country. Beside Jack and USA, I have a hyperlink Select, when I click Select, Jack will display on my textbox and supposed to be USA will display on my dropdown but not displaying instead it says an error "'cboCountry' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
I have tried the codes below:
protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
{
txtname.Text = GridView2.SelectedRow.Cells[1].Text;
cboCountry.Text = GridView2.SelectedRow.Cells[2].Text;
}
Only the textbox os working, no luck at all in dropdown...I'm using c# and asp.net.
I'm trying to find a way to remove an item that has been dynamically added when I change my drop down list selected user. The way this works is I add an edit and delete button dynamically when I select a user. I need to have the existing one be removed when I change users. Here is the code I'm using to build the two buttons. How do I remove them? Do I wipe out the columns and then add the columns again?
try {
dgvBG.DataSource = this.bgDataTableAdapter.GetData(cbPatientID.SelectedItem.ToString());
try {
Image editBGImg = Properties.Resources.editor;
Image delBGImg = Properties.Resources.del;
DataGridViewImageColumn btnBGEdit = new DataGridViewImageColumn();

Ihave a gridview which populated via selected item on my drop down list which I don't have any problem with that. My problem is I am trying to save multiple rows on my gridview into my database, for example I have added 3 items on my gridview which looks like this:
Id | Name
111 | Jack
222 | Nicole
333 | John
Now, I want all that under column Id which is 111, 222 and 333 will be save on my database once I click Save button I am trying the code below but it gives me an error saying "system.data.sqlclient.sqlparameter does not contain a definition for 'Values' and no extension method 'Values' accepting a first argument of type..." :
SqlConnection con = new SqlConnection("Data Source=GATE-PCSQLEXPRESS;Initial Catalog=dbProfile;Integrated Security=True");
SqlCommand cmdd = new SqlCommand("Insert into profile (Id, profile_id)VALUES(@id, @profile_id", con);
foreach (GridViewRow row in GridView1.Rows) {
[Code] .....
My table should be look like this once I am able to save multiple rows from my gridview into my database:
auto_id | Id | profile_id
1 |111 | 101
2 |222 | 101
3 |333 | 101

WPF window I'm working on. I have a window that has a textbox to enter a name to search a database table for, and when the search button is clicked, the ID for that username will be returned to a separate textbox. The code I've written atm doesn't seem to be working, but it looks fine to me. Here's what I've got;
private void btn_SearchUsers_Click(object sender, RoutedEventArgs e)
{
if (!string.IsNullOrWhiteSpace(txtb_SearchName.Text))
{
SqlConnection sqlCon = new SqlConnection(conStr);
[Code] .....
So, I have the value entered into the textbox to be searched for stored in a variable, I'm selecting the ID from the table when the name in the variable is found, storing the result in a DataTable, and then in my foreach loop, if I find the name (the name column being index 1 in the table), I set set the ID result textbox to equal the ID for that name (the ID column being index 0 in the table). I think the foreach part is what's throwing me off. Maybe the column stuff? My Users table is like;
ID Name
1 John
2 Roger
3 Mike
In my code below the first textbox.appendtext works but the second, textbox1.appendtext(i);, gives an error;
The name 'textbox1' does not exist in the current context (CS0103).
Is it possible to put text into the textbox from this routine?

public MainForm() {

I was following a c# book to write a WPF with a textbox. When the textbox is selected(got focus) with keyboard or mouse, it will select all text in it. I followed the book and wrote this:
private void TextBox1_GotFocus(object sender, RoutedEventArgs e) {
TextBox1.SelectAll();
} private void TextBox1_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e) {
var control = sender as TextBox;
[Code] ....
The book said having "e.Handled = true" is to stop the event in order to prevent the cursor being positioned on somewhere of the text instead of selecting all text. From my understanding, "e.Handled = true" is for stopping routed events. Is this means that something will run if "e.Handled = true" is not there? If yes, then what is it?
