Then, make sure AutoPostBack is set to true. This makes sure that the check boxes are refreshed everytime it's clicked. say you have a list item named "Select All" and a list item named "Select None". you check list is called "chklst" here is your method: public void comboClicked(Object sender, EventArgs e) { for (int i = 0; i < chklst.Items.Count; i++) { ///this says 'if select none is selected and the box you're on isn't the select none box, set the selected to false. if(chklst.Items.FindByText("Select None").Selected == true && chklst.Items[i] != chklst.Items.FindByText("Select None")) { chklst.Items[i].Selected = false; } if(chklst.Items.FindByText("Select All".Selected == true) { chklst.Items[i].Selected = true; } } If you’re doing in with ASP.net and want to do it in the code behind..

say you have a list item named “Select All” and a list item named “Select None”.
you check list is called “chklst”

here is your method:

public void comboClicked(Object sender, EventArgs e)
{
for (int i = 0; i < chklst.Items.Count; i++)
{
///this says ‘if select none is selected and the box you’re on isn’t the select none box, set the selected to false.
if(chklst.Items.FindByText(“Select None”).Selected == true && chklst.Items[i] != chklst.Items.FindByText(“Select None”))
{
chklst.Items[i].Selected = false;
}

if(chklst.Items.FindByText(“Select All”.Selected == true)
{
chklst.Items[i].Selected = true;
}

}

I had to remove the 'return false' part as it stopped after the first checkbox! I also notice that you are using ’checkbox’ which has to be converted to 'checkbox' (different quotes) Thanks for the script.

Another way would be to add it via this.Header.Controls.Add(); in Codebehind. hth Hi Yanna,

define a ContentPlaceHolder within the head tag of your MasterPage and add the script on the particular .aspx site to that ContentPlaceHolder.

Another way would be to add it via this.Header.Controls.Add(); in Codebehind.
