Command of dynamic controls

Question

User1571226316 posted

Hello,

 

I would like to create a button dynamicaly and assign an onclick event. This event is a redirection.

this is my code :

 

                Button btn = new Button();
                btn.Text = "Go !";
                btn.CommandArgument = reader.GetOracleValue(0).ToString();
                btn.CausesValidation = false;
                btn.Command += new CommandEventHandler(btnDynamique_Command);
                tCellbt.Controls.Add(btn);
                TableCell tCellbt = new TableCell();
                tr.Cells.Add(tCellbt);

 

I also tried with the parameter "PostBackURL" but I use SharePoint and there is a problem with it.

The code works with an other page, that's why I don't understand..

If you have any ideas..

 

Regards

Button dynamButton = new Button();

dynamButton.Id = "DynamButton";

void dynamButton_Click(object sender, EventArgs e)

{

throw new NotImplementedException();

}

This is the way i use and it's quite a standard. But it seems you are trying to use this in some sort of data binding. can you please reveal more what your are trying to do ..

As i have only used CommandArgument in the gridview or data grid. and where have you set the commandName

Hello tomar99

Assign a ID to your Button and write the code - in the best case - to Page_OnInit.
That should works.

What kind of issue coming up with Sharepoint and PostBackUrl?

It works.

It wasn't call during the page_load..

 

When I use PostBackUrl with SharePoint, it redirects me on the good url but I have to refresh the page (when I click, SharePoint says "the page change, you need to refresh the page....", I click on the link and after, I'm on the good page). Every time I have this message. That's why i need to use an other solution. And with buttons, it works !

 

Thanx

Hello tomar99

PostBackUrl makes a PostBack to another site, that means, the site is chancing.
That means fourther, you have to do a full rountrip / refresh.

Thats the theory, AFAIK.
