Checkedlistbox

[MFRASER]

How can I turn on and off what is selected? I have a checked listbox I want
Index 0 = "All" and each of the other nodes to be a number. If the user
selects all I want to uncheck all the other items and visa versa.

Here is what I have on the checked event. I can not get this to compile.

Thanks

private void lstIteration_ItemCheck(object sender,
System.Windows.Forms.ItemCheckEventArgs e)

{

if (e.Index == 0)

{

this.lstIteration.ItemCheck -= new
System.Windows.Forms.ItemCheckEventHandler(this.lstIteration_ItemCheck);

this.lstIteration.ClearSelected();

this.lstIteration..Items[0].Checked =
System.Windows.Forms.CheckState.Checked; //Line fails on compile

this.lstIteration.ItemCheck += new
System.Windows.Forms.ItemCheckEventHandler(this.lstIteration_ItemCheck);

}

else

{

this.lstIteration.ItemCheck -= new
System.Windows.Forms.ItemCheckEventHandler(this.lstIteration_ItemCheck);

this.lstIteration.Items[0].Checked =
System.Windows.Forms.CheckState.Unchecked; //Line fails on compile

this.lstIteration.ItemCheck += new
System.Windows.Forms.ItemCheckEventHandler(this.lstIteration_ItemCheck);

}

}

I got it to work like this

if (e.Index == 0)

{

this.lstIteration.ItemCheck -= new
System.Windows.Forms.ItemCheckEventHandler(this.lstIteration_ItemCheck);

this.lstIteration.ClearSelected();

e.NewValue =System.Windows.Forms.CheckState.Checked;

this.lstIteration.ItemCheck += new
System.Windows.Forms.ItemCheckEventHandler(this.lstIteration_ItemCheck);

}

else

{

// First show the index and check state of all selected items.

foreach(int indexChecked in lstIteration.CheckedIndices)

{

if(indexChecked == 0 && lstIteration.GetItemCheckState(indexChecked) ==
System.Windows.Forms.CheckState.Checked)

{

this.lstIteration.ItemCheck -= new
System.Windows.Forms.ItemCheckEventHandler(this.lstIteration_ItemCheck);

lstIteration.SetItemCheckState(indexChecked,
System.Windows.Forms.CheckState.Unchecked);

this.lstIteration.ItemCheck += new
System.Windows.Forms.ItemCheckEventHandler(this.lstIteration_ItemCheck);

break;

}

}

}
