The PK is coming from a source that displays a filtered subset of the data in a different order, so row numbers will not be the same.
Today's lesson is brought to you by the word "niggardly". Remember kids, don't attribute to racism what can be explained by Scandinavian language roots.

Do you use DataKeyMember and DataKeyValue of the GridView? If you do so, you can easily see bij setting the SelectedIndex if the SelectedValue meets the required. If not found on page, go to next page of gridview.
You can also create a DataView which has a filter option. If you use that, bind the dataview as datasource to the gridview.
If you want 1 row to show, why you don't use the details view. That's made for 1 row of data.

Well if u r using a datatable for binding to a gridview, then you may try this...
1. Loop through the datatable using a for loop..
for(i=0;i<=tbl.Rows.Count-1;i++)
{
if(tbl.Rows[i].Item[0]=="Your PK")
break;
}
2> Use the value of i to get the position of your item in the table.
3>Now to get the page No...
for ex if the page size is 10 and i=37
then
newpage=ceil(37/10)=4
ie jump to 4th page.
and to find the item in the 4 th page use 37 mod 10, which returns the index of the item.
Hope it helps....

I plan on allowing users to dynamically add, remove, and configure, menu items in a web site. Is there a nice way of providing the user with a list of eligible pages for links, or do I simply have to rely on detecting all pages in the main folder, or implement some kind of page manager?

It sounds to me like you are building a CMS. This is a big task. There may be open source ones available to you out there.
ASP.NET role manager may be of use if you want to build it yourself.
You can then allow certains users access to certain pages.

A very, very basic CMS function for a single site. They will have default menu items, and some optional informational pages that they would like to link to in the menu.

Do you store image path in Database? or in byte format?
If you store image path just set that path in src.
please don't forget to vote on the post that helped you.

Hi,
I'm creating a project in ASP.NET 2.0 using the controls GridView, FormView, and SqlDataSource. Everything is working as expected, but if the grid is empty FormView is not displayed. I've used separate SqlDataSource for GridView and formView. FormView is populated based on the row clicked in the Grid.
Initially grid would be empty, and New, Edit, Delete options of the FormView is not displayed coz formview itself is not displayed, coz grid has no data to display initially.
Is it possible to display the formview even if Grid is empty?
Regards,
Blumen

You can show a default message in the gridview saying that no rows are displayed.
You could count the number of rows displayed in gridview and if its less then 1 then just set formview visible to true, think that might work.
|
|
|
|
|
I tried that already, changing Visible to True doesn't display the FormView.

Hi All,
If we put our web app in our extranet(DMZ) is it possible to add external users to our companies AD? So if someone is given the address from outside they could access our web app. What sort of login would be needed if any?
DNM
|
|
|
|
|
We thought about creating a DMZ because we use citrix server and our app was hosted on there, so people would have to have access to our citrix to access it.
A DMZ is a good solution because it can act as a link between your network and a web server I think and therefore you can host your web app on a webserver.
Hope that makes sense

hi every one

}

but this is not working properly .
plz tell me
thanks...gaurav

what is not working properly?
did you do a debug?
Did you try to check the dr1.HasRows for true before using the While
If it is only 1 row of data you receive you should you if (dr.Read()). Only then you read the first row.
What type of object is .ImageUrl? Is it a String?
