Question

I have a datalist, and each item in the datalist has a checkbox and disabled button, I want when the checkbox is checked, the button will be enabled .

How to access the check box event for an item in the datalist ?

Answer 1

Please follow the steps given below:

1. Define OnCheckedChanged method of CheckBox at design time
2. In the OnCheckedChanged method find DataListItem
3. Find the required control in the DataList; you can find it in the current row as well using index of the current DataListItem
4. Change the enable property of the control you found

It’ll look something like this:

    protected void CheckedChangeMethod(object sender, EventArgs e)
    {
        CheckBox checkBox = ((CheckBox)sender);
        DataListItem item = ((DataListItem)CheckBox.NamingContainer);
        if (checkBox.Checked)
        {
            ((Button)dataList.Items[item.ItemIndex].FindControl("btnControl")).Enabled = true;
        }
     }

I hope this helps.
