Forms Data Controls :: SqlDataSource And DataGridView Not Updated On First Entry?

Apr 30, 2010

I have a web page with a Form a Button, a TextBox and a DataGridView in it. The DataGridView uses a SqlDataSource as its data source. SqlDataSource has one parameter which gets it's value from a
form parameter (TextBox1). When the page is opened for the first time I set the TextBox1 default value in code behind:

protected void Page_Load(object sender, EventArgs e)

Forms Data Controls :: DatagridView Postback / Cannot Make The Datagridview's Buttonfield Respond?

Feb 17, 2011

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?

Forms Data Controls :: Update 2.0 Formview Containing DataGridView

Feb 16, 2010

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.

Forms Data Controls :: DataGridView Equivalent Of GridView.Databind()?

Now I want to populate it: on a web page's code-behind I would write Gridview.databind(). What is the equivalent with a DataGridView.

Forms Data Controls :: Separate DataSource For DropDownList In DataGridView?

Sep 8, 2010

I am using a DataGridView and have a master table which contains values which different tables related to the master data, i.e. StatusID =1 in master table = TrailerStatus (1, 2, 3, 4 and their descriptions) are in a related table. I am able to retrieve the values from Table B 1 = Empty, 2 = Rejected, 3 = Onsite, etc. However, I don't know how to relate the master table StatusID = 1 to default my dropdown list from the relational table 1, 2, 3, 4.

I have been fighting with this for quite some time and just have not found a solid example of how to do this. I actually have two dropdownlists which will need to be correctly wired in order for my application to work.

This will also be an editable dataGridView but I will tackle that challenge once I get this first hair plucked from my butt.

There is some code-behind which doesn't work at all pertaining to a ;; gvSCACDetail_RowDataBound ;;

but I dont' think I can even get the code to compoile when this is not commented out.

Here are some of the details:

<td style="width: 700px; height: 20px">
<asp:GridView ID="gvSCACDetail" runat="server" AutoGenerateColumns="False" AutoGenerateEditButton="True" DataKeyNames="trailerid,locationid,scacid,statusid,capacityid" AutoGenerateDeleteButton="True" DataSourceID="SCACDetailView" Visible="False" Width="698px">
<PagerStyle CssClass="centerh" HorizontalAlign="Center" />

Forms Data Controls :: Merging Two Sets Of Data Onto One Datagridview?

I have two SQL queries that are stored procedures that have 2 variables that my web form will be supplying through text boxes. The two queries will produce two different results. I have read a couple of different of the MSDN articles online, including this one:

that say that the tables must be similar to be able to merge them into a single datagridview. I know that datagridviews only like one table at a time, but I was curious if anyone had found a way to merge two dissimilar tables to one datagridview or not.
