Hello All,

I am working on ASP.NET 1.1. I am using a Panel control to add some controls at the runtime. Now the problem is that when the page displays, the panel moves to the bottom of the page. I have the panel in a table, but it moves out of that table and goes to the bottom. I am screwed up by this issue. Any help is very much appreciated.

thanks,
Mubashir

This is quite wide topic, but generaly you need to have Role class with method IsUserInRole(...),
then you can display/hide controls in accordance with what this method returns. Do not reinvent wheel, see .NET Provider model:

This article[^] details how to retrieve an image from a database.

Basically, you create an aspx page called something like LoadImage.aspx.
The LoadImage.aspx page contains the code to get the image from the database (the aspx page content doesn't matter as it gets replaced by the image data).

///
/// imageData is the data loaded from the database in the Page_Load
///
private void ShowImageData(byte[] imageData)
    {
        // Clear Response buffer
        Response.Clear();

        // Set ContentType to the ContentType of our file
        Response.ContentType = "image/jpeg"; 

        // Write data out of database into Output Stream
        Response.OutputStream.Write(imageData, 0, imageData.Length);

        // End the page
        Response.End();
    }

Then in you web page where you want to display the image, you just put a link to the image: e.g. where the imageID is the image id in the database to load. This would be accessed in the Page_Load of LoadImage.aspx

Hi all

I am building a project by ASP.Net (VS2005) Framework 2.0
I have use GridView, When i use GridView have Datasource = SqlDataSource so VS2005 support
afterthat i add CommandFiel is "Edit, update, cancel" and use Event "GridViewUpdateEventArgs"

void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string[] strValues = new string[3];
int i = 0;
foreach (DictionaryEntry entry in e.NewValues)
{
strValues[i] = Server.HtmlEncode(entry.Value.ToString());
i = i + 1;
}
}

When i use GridView have "Datasource = SqlDataSource" so strValues[i] have value
but when i dont use "SqlDataSource" so i get data to database by

string strQuery = "Select * from Categories";
SqlConnection connect = new SqlConnection(strConnection);
SqlDataAdapter da = new SqlDataAdapter(strQuery, connect);
DataTable dt = new DataTable();
da.Fill(dt);
GridView1.DataSource = Datatable;
GridView1.DataBind();

strValues[i] haven't value and it not run to loop "foreach"

Hi there,
This is one of the advantages of using the DataSource control, that said the NewValues dictionary is only populated when you use the GridView control with a datasource control like the SqlDataSource. So in your case, you need to manually get the new values from the input controls in the edit row of the gridview like you did with the datagrid control in the old days.

Hi...thanks for your help but do you have any idea if I want to authenticate all users with different domain controller? without setting any userid and password?

Our scenario is we have different domain controller. We want to have a web page log-in that will have different access depending on the domain they will log. Our Active Directory ID password is reset every month and I only have an access to only one domain so I cannot use configuration with user id and password parameter.

Thanks for your help again in advance.

How to Set the URL befor PostBack (Passing Data in URL) [modified]

4-Oct-06 20:52

Hi,

I wish to implement the PostBack to the Same Page, BUT with Different Data Values. (I am Passing the Data in URL).

When i click on some server control (for ex Anchor,LinkButton & <a href=""> ), the URL need to be modified immediately.

For example, I m having 10 pages numbered 1,2,3,..10 (conside each page no as any one Navigation control), and when i clicked on the no 1, immediately the URL's page value need to be changed to 1. Like this for all page no. BUT before the PostBack occurs.

xyz.aspx?page=1

B'Coz, in my Page_Load event handler i wish to get that page value using Request.QueryString["page"].

How to achieve this? Which CONTROL i have to use for PostBack to occur to the same page WITH modified URL value?? OR any other solution for this?

Regards,

Jay

u can initialize the page variable on the first page Page_Load and then increment and decrement that variable depending on what u need

as for the postback thing ... i'm not sure about it

Hi,

Thanks for your suggestion. But i have to SET the Page value in URL only, B'coz it has used for many other purposes in the aspx Page.

Now i have used LinkButton Control and set its PostBackUrl property in the Page_Load event handler.

string pageIndex= Request.QueryString["page"].ToString();<br />
LinkButtonID.PostBackUrl= "Products.aspx?&page="+pageIndex;

The thing is that, i have to check for Page.IsPostBack in the Page_Load.It works fine. Smile | :)

Previously my problrm is that, i have set it in the Click event handler of each LinkButton.

Why do you want the main to stop working? What does it do when you open the pop-up window? IMO, you may simply use the showModalDialog method to pop up the window and while he's working on this pop up he cannot access the main page.
