Re: A4 page size and Image

That's not how it works. You should be able to tell the size of the image the printer can accept, from the printer, and then size your image accordingly. Most printers have huge resolutions, as they are far more than 72 DPI.

Try putting the path in quotes, but it should not matter. Where is the images directory ? Where is this html, relative to that directory ?

This is just a simple case of tinkering with your file paths.

Try:string bodyHTML = "<html><head></head><body>" +"<img src='/images/h.gif'>" + "</body></html>";

Use single quotes around the source location, also try simply putting a '/' before the image location. Some servers are set-up such that they may or not require the prefix of a forward slash.

You could also try using some sort of mappath code to find the true location of your images folder.

Putting an image tag in a string doesn't automatically display the image on the page. What do you do with the string after creating it?

It seemed to work okay for me. Make sure your image is in the correct location in the file structure and the name is correct. Otherwise, not sure. Maybe try adding ...what browser are you using?

Hi,

I am dynamically creating linkbuttons in asp.net c#. After creating the button i have to assign button click event for which i have written the below code.

btn.Click += new EventHandler(btn_Click);

The same works find when i am writing the code in codebehind but since this code is repeated in all the pages i have to use a class, but the problem is that the btn_Click method is in the codebehind page so how can i assign the eventhandler btn_Click event of the parent page while hooking up the event in the class.

Can someone please help me out.

Please see below the code:

protected void CreatePageCounter()
{
int pagesCount = (int)GetPagesCount();

int linkCount = 0;
for (int i = 1; i <= pagesCount; i++)
{
LinkButton btn = new LinkButton();
btn.Text = i.ToString();

btn.EnableViewState = true;
btn.Click += new EventHandler(btn_Click);
plcHldrPageNo.Controls.Add(btn);

plcHldrPageNo.Controls.Add(new LiteralControl(" "));
linkCount++;
}
}

Regards,
Anees

By defining a delegate in this class, hooking it to the parent class, and then calling that delegate when your event fires ( which you can do inline with an anonymous method if you want ).

Also, make sure you create these before page load, or they will not fire, as they will lose their viewstate.

Hi,

Thanks for the reply.

I understood what u have said but i need to call the method (btn_Click) in the page itself and just hookup the event in the class. Is it possible.

Extending the Edit functionality of the GridView

11-Sep-07 2:40

I don't see why it's necessary ( it almost certainly isn't ), but unless you put an instance of your page inside the class, and then make the methods that are called public, I don't think it's possible. A delegate that you fire when creating the buttons may do it, also, if it passes the button out, so that it can be hooked up in the outer class.

Hi all,

I have a GridView control with edit functionality. When a user edits any of the fields and clicks the update button, I need to copy both the old values and the new values entered by the user into a log table. Can someone please advise on how I can achieve the following using VB code? :
1. Get the original values before the edit operation
2. Get the new values entered in by the user (about to be updated)
3. Save the old and new values into a log table

Thanks!

Write a Update Trigger on the database side. The value that you are looking for(old values and New values) will be available in the pseudo tables(logical tables). Doing this in the front-end is a wrong coding approach.

Thanks J O N!

I'm looking for examples of how to do this. There's one in Books online but still a little over my head.

Would still like to know how to do it the ASP.NET way though...

Before Updating the New values get the old values from the DB by passing the ID as parameter and New values you have. Have these two in DataRow() and then do the Update followed by Insert Into logtable(old vaules and New Values from the DataRow Collection) .

if you are Binding GridView with SqlDataSource then use FilterExpression of SqlDataSource then bind again GridView

example:

SqlDataSource1.FilterExpression = "ColName ='"+getSelectedItemofDropDownList+"'";<br />
GridView1.DataBind();
