Forms Data Controls :: Appending Datagridview Record From Textbox?
Nov 1, 2010
I'm new to asp.net. I have an exercise about datagridview.
Basically it's like this, I created a sql database in visual studio, added some tables and records. I added a gridview to my page and change the datasource to 1 of my tables. It displays every thing fine.
Now my exercise is, I need to add a new record to that table from a textbox control and button submit, and display in gridview after page reload.
DataTable dt = new DataTable();

I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

I've got 2 DropDownList controls. The 2nd one is dependant upon the choice of the first.
This bit is working... sort of
When I make a selection in DDL1 I get the right list of items in DDL 2, but if I were to change DDL1, I get a further list of items appended to DDL2
It just keeps stacking up the list items.
I've got AppendDataboundItems to True, because I need a blank as the first item in order to use the SelectedItemChange event.

Now this AddGridAddBTN Temporarily adds a data row to a grid but won't submit that data to database, however AddGridSubmitBTN Submits the data to DB through foreach loop .
Now my query is i want to provide user a functionality that when he gets focus on Abbreviation Text Box OR Description Box and he after typing some data Press ENTER KEY , This ENTER KEY would provide funcionality as a AddGridAddBTN Button , and when he presses SHIFT + ENTER , It works like AddGridSubmitBTN Button , also i want to make Abbreviation and Description Field to be filled must !
Moral is that :
ENTER KEY WOULD DO : Generate a temporary row with holding previous values as it is actually doing on AddGridAddBTN Button.
SHIFT + ENTER WOULD DO : Enter the whole grid data thorugh foreach loop as it is actually doing on AddGridSubmitBTN Button.
I don't want to refresh my page on enter or shift enter pressing . This grid is binded through SQL DATA SOURCE ...

I am working on an asp webform that pulls from an ODBC datasource then puts the data in an sql server. Once the data is in the sql server several queries pull data from it to provide information for a report.
This is an example of what I am talking about
private
void ODBCpdEmployeeAb()
{
DataTable dt =
new
DataTable();
[Code]....
The first part gets the data from the ODBC connection and the next part stores it in an sql server table. The problem is I have these methods in the page load event of the webform so everytime it loads it just puts the exact same data in the sql server table which would then provide incorrect information on the report.
Is there a way to append the most recent data from the ODBC table to the sql server ?

Trying to update a .NET .20 datagridview in the following scenario. A page contains a formview. The formview contains a datagridview and some other fields not in the grid. The formview has its own ObjectDataSource and the datagridview has a separate ObjectDataSource. Each ObjectDataSource has an OnUpdating event. Clicking a Save button triggers the formview update event and the "non-grid" ObjectDataSource updates without a problem. In that same event, I also want to update the grid's ObjectDataSource. Because it's a grid, this OnUpdating event has to loop through each row, get the data for that row and set the UpdateParameter values. A foreach loop can get the values, but how do I trigger the update before looping to the next row?
Should I try calling a different kind of event for the DataGridView's ObjectDataSource? Or is there a way to get all the grid's new data at once as a dataset or datatable and do one bulk update? The datagridview does not have row-level edit/update buttons. It is meant to be an all-or-nothing kind of update.

for (int i = 0; i < GridView1.Rows.Count; i++)
{
GridViewRow row = GridView1.Rows[i];
//Change Color back to white
row.BackColor = System.Drawing.Color .White;
//Apply text style to each Row
row.Attributes.Add("class" ,
"textmode" );
}
GridView1.RenderControl(hw);
//style to format numbers to string...........

I need to add 3 rows to a footer, i did a total but dont know how to add 2 more,
I have a variable credits that i would like to display on the next line and then net the 2 on the 3rd line.
I have looked at properties of the e.Row and was thinking if i could add a table?? Is there a to table method of datagridview? That way i could add the rows?
protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Footer)
{
double totald = Convert.ToDouble(dt.Compute("Sum(Bal)", string.Empty).ToString());
e.Row.Cells[0].Text = "Total";
e.Row.Cells[0].Attributes.Add("align", "left");
e.Row.Cells[2].Text = string.Format("{0:n0}", totald);
e.Row.Cells[2].Attributes.Add("align", "center");
e.Row.
}
