Forms Data Controls :: Adding A Document In A Website With A Datagridview?
Dec 10, 2010
I created a website with a datagridview and I would like to add documents per line, actually a inserted there the next option
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False"
ReadOnly="True" SortExpression="ID" />
<asp:BoundField DataField="Week" HeaderText="Week" [code]....
it works really good, the only question is that how can I load the file with the button of "update", from the datagridview, how this code should be written?

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?

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.

Response.Clear();
Response.Buffer = true ;
Response.AddHeader("content-disposition" ,

HtmlTextWriter hw =
new HtmlTextWriter (sw);
GridView1.DataSource = RecordsDataSet;
GridView1.DataBind();
GridView1.AllowPaging = false ;
GridView1.DataBind();
GridView1.HeaderRow.Style.Add("background-color" ,
"#FFFFFF" );
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.
}
}

I have spent most of my time writing ASP.Net web pages, using VS 2005. I am now developing some client function for Windows, so I'm relatively less expert in VB.In my Windows program I have defined a DataGridView and linked this to a data table (within a tableadaptor). 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.

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 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)

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" />

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:
[URL]
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.
