Dynamic Checkboxes problem!

[Steven]

I create the checkboxes dynamically on my webform (aspx). after I create
them, when I check any of the checkboxes, nothing happens. Here is my code
...

ArrayList LayerNameList1 = LayerNameList;

CheckBox[] checkBoxArray;
int BoxCount = 0;
HtmlTableRow newRow;
HtmlTableCell FieldCell;

System.Web.UI.H tmlControls.Htm lTable ContainerTable = new HtmlTable();
checkBoxArray = new CheckBox[250];
foreach(string item in LayerNameList1)
{
newRow = new HtmlTableRow();
FieldCell = new HtmlTableCell() ;
FieldCell.Style .Add("font-family", "Arial");
FieldCell.Style .Add("font-size", "smaller");
checkBoxArray[BoxCount] = new CheckBox();
checkBoxArray[BoxCount].ID = Convert.ToStrin g(BoxCount);
checkBoxArray[BoxCount].Text = item;

checkBoxArray[BoxCount].CheckedChanged += new
System.EventHan dler(checkBox_C heckedChanged);

FieldCell.Contr ols.Add(checkBo xArray[BoxCount]);
newRow.Controls .Add(FieldCell) ;
ContainerTable. Controls.Add(ne wRow);
BoxCount++;
}
this.placeHolde r.Controls.Add( ContainerTable) ;
}

public void checkBox_Checke dChanged(object sender, System.EventArg s e)
{
CheckBox cb = (CheckBox) sender;

if (cb.Checked)
{ testdel.Text = "1"; }
else
{ testdel.Text = "2";
}
}

Any suggestions?

Hi Steven,

I think you should set AutoPostBack="T rue".

Hello Peng,

Could you please tell me, where should I set AutoPostBack="T rue" in the
below code. I tried in checkBox_Checke dChanged function. But seems I'm
missing something.

What I mean is you can add

checkBoxArray[BoxCount].AutoPostBack = true;

into your foreach statement.
Then you can fire server side event and call CheckedChanged function.

Copied your code into a empty web form, like below,

LayerNameList1. Add("test3");

CheckBox[] checkBoxArray;
int BoxCount = 0;
HtmlTableRow newRow;
HtmlTableCell FieldCell;

checkBoxArray = new CheckBox[250];
foreach(string item in LayerNameList1)

Thank you for the code and explanation.

If I recreate the controls on page load everything works fine. But I do not
want to recreate the controls on page load. I just want to create the check
boxes only when I click the button.
