Create Image from html string

10-Jan-08 3:06

You need to set DataSourceID on the GridView:

<asp:GridView ID="GridView1" runat="server" DataSourceID="AccessDataSource1"></asp:GridView>

I am not getting what you are trying to do. How you can create image from a HTML string ?

Graphics has DrawString method to draw image from string.
But in my case I have string in html format.

You can better understand by this Link

I don't think that DrawString() can parse HTML tags and draw the output. If you just want to draw plain text, remove HTML tags and draw. If you want rendered output of that HTML, then you need to use other GDI methods to create that and draw it.

Hi I am using a GirdView under one colume is hyperlink. I want that when i click the hyperlink then display msgbox. "Do you want to Open the --- page" Yes Or No. if Yes then goto another page.

Here is a simple piece of javascript which prompts before redirecting:

<script type="text/javascript">
    function go(pageTitle, pageUrl){
        if (confirm("Do you want to Open the " + pageTitle + " page?")) {
            window.location = pageUrl;
        }
    }
</script>

<a href="javascript:go('Cool', 'cool.aspx');">Go to New Page</a>

You should be able to integrate this into your GridView hyperlinks.

how many characters does an hidden field holds

10-Jan-08 2:53

The confirm box is part of the browser so you have limited control over it from javascript.
If your know that your target audience is exclusively IE then you can check out this solution[^].

For a more browser independent approach you can implement your own popup, here is an example[^].
The disadvantage with this approach is that popup blockers will block it.

You can also use the ModalPopup[^] control which is part of the ASP.NET AJAX framework.

Text file and view state data

A normal HTML input text can hold 2147483647 values. So I guess hidden field can also hold that

You can't load viewstate data from a string. If you want to show it again when user visits, store the values in database/session, and reload it.

But, i need to give the text dynamically, rather creating many buttons.

Is there any way to create the Image buttons with text dynamically

Use classes in GDI to draw text over the image.

You can use a LinkButton control to display both text and an image:

<asp:LinkButton ID="LinkButton1" runat="server" Text="<img src='images/submit.gif' alt='' />Submit"></asp:LinkButton>

You can also specify a CssClass if you want to set a background image.
