Emitting simple plain text rather than HTML

20-Dec-06 9:45

I have a gridview with a link in the parent page.when i click on the link it opens up another gridview.this child gridview has 2 columns,one is a checkbox created using an itemtemplate and another a boundfield retreiving data from the database.what i want is when i check the checkbox of a particular row and hit a button,the data existing in that particular row of the child gridview which has been checked,has to transfer the data from that row to the parent gridview,in a sense the parent gridview has to refresh and show up with the new data that has come from the child gridview control.How can i do this?..........urgent..........

hi,
I want to pass some text data to FLASH from ASP.NET and I dont know how to emit simple and plain text from ASP.NET page rather than emitting a whole HTML page. My programming language is C#.NET 2.0

I appreciate your co-operation.
Thanks and regards
Emran

You can create a new WebForm completely free of markup, then override it's Render method:

protected override void Render(HtmlTextWriter writer)<br />
{<br />
	writer.Write("This is the only content I want to emit to the browser.");<br />
}

if you are using sql server it is so much easier to create a dts package, use the vb.net app to save the .csv file to the proper location then call the dts package from you app.

Other wise check here for a C# example that you can convert to vb.net.

Modifing web gridview control

Hi Everyone:
I have a unique requirement. I need to display data in a gridview and be able to add, edit or delete records from a web page using the gridview control.

The web control "FormView" will do all the operations, but it only shows one record at a time. The Gridview control shows all the records and will allow the user the ability to edit and delete records, but not add new ones.

Does anyone know how to combine the viewing capibilities of a gridvierw control and the record operations of the FormView into a single control?

Thanks in advance,

Mark McCumber

Mark, I have never used the "FormView" control. What I have done in the past is to store my gridview data as a DataTable serialized in ViewState. Then I give the user the option to add a new record and then add a new row to the datatable retreived from Viewstate and rebind it to the grid view.

The FormView control will automatically add a new record to a SQL database if you have the sqldatasource control configured to allow edits, deletes and inserts.

The formview control was built for data entry, but it would not show all the records like a gridview. My IT manager wants the form to look something like an Excel spread sheet, but have the fields in columnar form so the person entering the data can't make mistakes.

Thanks,

Oh well, I tried. It looks like you might have to do some programming instead of just relying on .net webcontrols.

I was afraid of that Smile | :)

. I'm trying to create a Web based application that behaves like a Windows application. One that has a form and as you click the next button the data in the form changes.

Nothing is ever easy. I have always wondered why they call it "Rapid Development" when you still have to create code to do the required tasks.

If you are using a datatable, you can sort those.
Dataview dv = new Dataview(DataTable);
dv.sort = "AutoId desc";
DataTable = dv.toTable();
datagrid.datasource = DataTable;
datagrid.databind();

i am not using any data table. How can you use the Order by Asc?

You have to use DataView to enable the sorting
just insert that table in dataview and call the sort property by giving the column name and ASC or DESC

example
dataView1.Sort = "Country DESC";

Happy Coding

Re: render values from check box and update to database on button click

20-Dec-06 7:56

I have a gridview which contains columns retreived from the database.i have in total 12 columns,in which 4 columns have checkbox's where ever there is a null in the database.i have done tht on the rowdatabound event of gridview dynamically by calling

CheckBox cb= new CheckBox();

i also have a checkbox in the first column of the gridview created using an itemTemplate tag of gridview,so tht when we check the corresponding row's checkbox,the values in tht row shall be updated
now my question is,i want to check the boxes in the column cells and update those corresponding row values in the database on button click.and also i need the checkbox state to be maintained.......how can i do this?any responses will be appreciated.

ToddHileHoffer20-Dec-06 8:11

To make this just a bit easier. Create a template column in your gridview. Hide the checkboxe in the itembound event when the database value is null. That solves the problem of maintaining the viewstate of the grid.

Now to loop through your gridview. Here is some sample code to put behind your button (or during any event really).

CheckBox cb;
foreach (GridViewRow r in this.GridView1.Rows)
{
cb = (CheckBox)r.FindControl("cbUpdate");
if (cb.Checked)
{
//put code to update database
}
}

Thanks for the reply.but it has not solved my problem completely.i have done similar to what u have replied,but in my case i need to loop through the inner cells of the gridview and as well the rows and check if there is a checkbox at any cell in the gridview,if exists,based upon my requirement i have to click the checkbox in those cells and also check the checkbox in the first column,and then update.what i want is to check the checkbox in the gridview cells and also the checkbox field created using the itemtemplate in the gridview.when i check the cells with checkboxes and then check the checkbox that is existing in the first column of the gridview and click the update button,then the data in the corresponding row should update.....

DataGrid not fiiring ItemDataBound event

20-Dec-06 10:06

yes,the question is in my previous mail,to simultaneously check the chekbox in the cells of cells[7],cells[8],cells[10],cells[11] and then click the checkbox in the itemtemplate to update it to the database.

how to do this?

The Data Grid (at class level):

Protected WithEvents dgProducts As System.Web.UI.WebControls.DataGrid

Setting up the event handler (in a method called from Form_Load):

AddHandler dgProducts.ItemDataBound, AddressOf dgProducts_ItemDataBound

The event handler:

Private Sub dgProducts_ItemDataBound(ByVal sender As System.Object, ByVal e As DataGridItemEventArgs)

dgItemDataBound(sender, e, dgProducts, "ddl_4")

End Sub

The problem (VB.Net, ASP.Net v1.1):

A breakpoint set on the single line of this event handler is never hit even though this DataGrid does contain a DataBound column that does display data.

I think in VB.Net you need to put the handles keyword after the method.

<br />
Private Sub dgProducts_ItemDataBound(ByVal sender As System.Object, ByVal e As DataGridItemEventArgs) handles dgProducts.ItemDataBound<br />
