Binded DropDownList with ToolTip

Question

Hi I have a DropDownList bounded from the code behind. How can I use the DataTextField as a ToolTip of the DropDownList?

DropDownList list = this.DropDownList1;
list.DataSource = GetData();
list.DataTextField = "DisplayString";
list.DataValueField = "DataValue";
list.DataBind();

I want the bounded Field DisplayString to bounded also in the ToolTip. Is this possible without using the DataBound event of the DropDownList?

Solution 1

Simply call that function after dropdown list binding: BindTooltip(Name of the dropdownlist);

public void BindTooltip(ListControl lc)
{
    for (int i = 0; i < lc.Items.Count; i++)
    {
        lc.Items[i].Attributes.Add("title", lc.Items[i].Text);
    }
}

Solution 3

Below code will work, need to call this method in PageLoad and pass the dropdown list to the method for which you want tooltip

 protected void Page_Load(object sender, EventArgs e)
 {
    BindToolTip(ddlProjects);
}

Below is the actual method:

private void BindToolTip(ListControl list)
{
    foreach (ListItem item in list.Items)
    {
        item.Attributes.Add("title", item.Text);
    }
}

close, but I want the tooltip for each list item, not only on the selected item.

same thing can be implemented on hover effect as well
