I'm making first, last, next, prev buttons outside of the datagrid. The labels/buttons that are assigned value/commands respectively based on which row of the datagrid is selected (which only needs to have dataBind on the first page load). Then, if the button outside the datagrid is pushed, I want it to go to the correct row of the datagrid and display a hidden cell of the datagrid in a label field. What is the correct syntax for pulling a datagrid's hidden column based on a button click outside of the datagrid? If you look at the code below, the correct row in the datagrid is highlighted when I push the next button, but I can't get the syntax right to have the lblPgTitle (outside the datagrid) display the hidden cell of the datagrid. (datagrid cell specifically is DataField="pgTitle")
sub pgNext(sender as object, e as eventArgs)
dim n as integer=cint(lblNext.text)
dgNavList.selectedIndex=n
lblPgTitle.text=dgNavList.item.cells(1).text
end sub
Tried another tack going through the onSelectedItemChanged in the datagrid
withcoe below but get an error of identifer expected.
Sub navNav(Sender as object, e as eventArgs)
Dim itemTitle As TableCell =
dgNavList.Items[dgNavList.SelectedIndex].Cells(1)
lblPgTitle.text=convert.toString(itemTitle.text)
End sub
Any ideas? There's got to be a way to reference it.

For anybody else out there, here's what worked - did not involve viewState and did not involve onSelectedIndexChanged by the event method of the button:
sub pgNext(sender as object, e as eventArgs)
dim n as integer=cint(lblNext.text)
dgNavList.selectedIndex=n
Dim itemTitle As TableCell = dgNavList.Items(n).Cells(1) lblPgTitle.text=convert.toString(itemTitle.text)
end sub

I'm looking for some code I can drop in to allow users ( a very select, authorized set of users ) to browse for files on the server and use them to dynamically create web pages.
Does anyone have a link to stand-alone code for doing this? I've found code here bundled into projects that does way more than what I need (I'd trim it down but it's hard to tell what is required and what isn't). If you have a link to something clean and concise I'd appreciate it.

Oops  ! I misunderstood what you need, I just thought that you might be talking about something that prevents the unauthorised user from browsing (accessing) your web pages (files), sorry Rex  .

I have a HttpHandler that does that. However I would have to modify it for you to add the users allow to do so. Let me know and I can make it work for you.

The users can only access the entire management tool from a certain machine. If they are not on that machine nothing works. Once they are in the system no authentication is required.
I only added that part about security to avoid a bunch of people telling me I had a bad idea or whatever. I just need some code to browse for files on the server.

Are you viray?
Well, the article shows you the way of using ADO.NET to save the image binary data to DB. Have you seen that? The article also gives you the sample code to pull the image from DB and display on the web page.

In an asp.net 2.0 GridView, as well as the fields from a database, there are columns for edit, select, delete.
How is it possible to enable/disable the columns such as edit or delete in the datagrid?
The reason I would like this is so that an Admin will be able to edit or delete but a normal uses will not be able to.
Thanks

In design mode, disable edit or delete column in your gridview. After that, in your code (in Page_Load), add these code:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack && userType == UserType.Admin)
{
//Enable Delete
CommandField deleteField = new CommandField();
deleteField.ShowDeleteButton = true;
this.GridView1.Columns.Insert(0, deleteField);
//Enable Edit
CommandField editField = new CommandField();
editField.ShowEditButton = true;
this.GridView1.Columns.Insert(0,editField);
}
}
Hope this help.

If you use the CommandField in the GridView control, then this field supports a couple of properties, for example ShowEditButton, ShowDeleteButton which you can use to set based on the user is currently accessing the web page. In addition, you can also use the TemplateField to contain the Edit/Delete button controls, and you simply set the Visible property of the controls depending on the user type. For more information, you can see MSDN[^]MSDN.

How about using something like
grid.column(5).visible=false based on the logged in user ?
Thanks

This way is also an option if you want to hide the entire column.

But when I mention a Text File's URL which resides on a Web Server then it does not accept path in URI form.
Please let me know how to read text file which does not resides on local machine
Thanks
Lets work it Out.........!

"Did not work" is not sufficient to help you solve the problem. Post the code used, the error message any any other relevant information.

First of all,I would like to tell thank you very much for your attention...
The problem is very clear I think..
INSERT INTO tbl1 VALUES
(........)
How can I convert the TextBox string to a SmallDateTime value?
|
|
|
|
|
string strSQL="INSERT INTO SupplierOperations VALUES ("
+ txtOrderNum.Text + ",'"
+ txtModelNum.Text + "','"
+ ddListVendor.SelectedItem.Text + "','"
+ DropDownList3.SelectedItem.Text + "','"
+ txtModelType.Text + "','"
+ txtModelExp.Text + "','"
+ ddlistGrup.SelectedItem.Text + "',"
+ Convert.ToDateTime(Textbox2.Text) + ","
+ Convert.ToDateTime(TextBox1.Text) + ","
+(TextBox6.Text) + ","
+ txtTerminDayCount.Text + ","
+ txtOKcount.Text + ","
+ txtConditionCount.Text + ","
+ txtStopCount.Text + ","
+ txtTotalCount.Text + ","
+ txtControlCount.Text + ","
+ txtMajor.Text + ")";
try
{
CollConnection.Open();
SqlCommand cmd=new SqlCommand(strSQL,CollConnection);
cmd.ExecuteNonQuery();
.
.
Enough??
