Error table 0 cant be found

30-Jan-07 10:58

It means you have a web config that sets this key, below your main directory. You need to define this directory as an application of it's own, or remove the entry.

If it doesn't exist, you have an empty dataset.

You can use a WebRequest or a WebClient object to request the page.

How I call the event handler ?

Hi.

I'm a new member here.
My English is not very well, but I hope it´s good enough to make you understand me.
Well...
I'm with a litlle problems here.
I registered a "Click" event
handler for the dynamicly added control. However, when I
click the control , its event handler isn't called. But If I add and register the event handler operation in the Page_load, it works well.

Here is the code:

protected void CreateTable()
{
HtmlTable tablegen = new HtmlTable();
HtmlTableRow rowgen = new HtmlTableRow();

for (int i = 0; i <= 2; i++)
{
HtmlTableCell cellgen = new HtmlTableCell();
if (i == 0)
{
cellgen.Width = "50px";
cellgen.Align = "center";
cellgen.InnerText = "......"
}
else if(i == 1)
{
cellgen.Width = "50px";
cellgen.Align = "center";
cellgen.InnerText = ".....";
}
else if(i == 2)
{
cellgen.Width = "50px";
cellgen.Align = "center";
ImageButton imgButton = new ImageButton();
imgButton.ImageUrl = "Test.gif";
imgButton.ToolTip = "Test";
imgButton.Click +=
new ImageClickEventHandler(imgButton_Click);
cellgen.Controls.Add(imgButton);
}
rowgen.Cells.Add(cellgen);

}
tablegen.Rows.Add(rowgen);

I call this method from a click event of a button.
I need to create controls, in this case ImageButtons, that are
dynamically loaded, and they must be allocated in the third cell of a table in every row. The curios is that they don't call the event handler when created out of the Page_Load.

Somebody can help me ?

Maximilian Thanks

If you add controls dynamically, they need to be recreated before the Page_Load event ( usually in LoadViewState ), or the viewstate won't be restored for the control in time for the event to have a control to attach itself to, so it will be lost.

Set the event in the page_init

<br />
 protected void Page_Init(object sender, EventArgs e)<br />
        {<br />
            CreateTable();<br />
        }<br />
<br />
   protected void Page_Load(object sender, EventArgs e)<br />
        {<br />
            this.Init += new EventHandler(Page_Init);<br />
         }<br />

Multi lines of text in a Gridview

I have a Gridview connected to a Access table. One of the columns in the Gridview displays address, city, and state. How can I display this information on three separate lines within the cell for each row?

Our end goal here is to create a reality listing page that displays a small picture of each house along with multi line descriptions. I'm trying to use a Gridview for this. Is this the best way?
I want the page to look like this:

+ + + + + 123 Smith Ave
+ + + + + Maumee, OH
+ + + + + Price: 200,000
+ + + + +

+ + + + + 5422 Conant
+ + + + + Maumee, OH
+ + + + + Price: 168,000
+ + + + +

Use a template column.

Using Template columns might help. Also search msdn for onitemdatabound event.

Yeah I have done that.

Off the top of my head do a for loop for each gridview row in the grid view. Then use row.findcontrol() to get your check box and other values to update the database.

BTW, I got burned doing this because we had a group of users using the same application and some people would keep it open all day and save at the end of the day effectively overwriting what others had done. Be sure to add record locking of some sort if you are going to users update a group of records at once.

I work on VS 2005

How do i use the HtmlWriter class to add html tags to my web page using csharp code?

I have only a vague idea about this class.

Can you give me an example and show how i can do that?

Thanks in advance.

Thanks Jasmine..

I wanted to know how to make use of the HtmlTextWriter class for doing it.
(sorry it wasn't HtmlWriter!)

There are other classes also that are used like the HtmlTextWriterAttribute , HtmlTextWriterTag and HtmlTextWriterStyle classes.

Can you help me use these classes?
Thankyou.

Well, I don't see why you want to do things the hard way, but I suppose you must have a reason. There's good sample code for HtmlTextWriter in the MSDN documentation. Took me two clicks to find it.

Why are you using this?
