Hi,
check the code below it can help u.
FormFunctions.js
..
//checks all DataGrid CheckBoxes with the given name with the given
value
function CheckAllDataGridCheckBoxes(aspCheckBoxID, checkVal) {
re = new RegExp(':' + aspCheckBoxID + '$') //generated control
name starts with a colon
for(i = 0; i < document.forms[0].elements.length; i++) {
elm = document.forms[0].elements[i]
if (elm.type == 'checkbox') {
if (re.test(elm.name)) {
elm.checked = checkVal
}
}
}
}
..
The script takes the name of the DataGrid CheckBox to be checked and the value
to apply (checked or unchecked).
In your .aspx file, you need to include the JavaScript file as follows:
MyForm.aspx
..
<HTML>
<HEAD>
...
language="javascript"
src="/MyWebApp/MyUtils/FormFunctions.js"></script>
...
</HEAD>
..
Finally, add the CheckBox to your DataGrid, including a call to the script in
the onclick event:
MyForm.aspx
..
<Columns>
<asp:TemplateColumn>
<HeaderTemplate>
<input id="chkAllItems" type="checkbox"
onclick="CheckAllDataGridCheckBoxes('chkItemChecked',
document.forms[0].chkAllItems.checked)" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox id="chkItemChecked"
runat="server"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
Regards,
Akshit
