Reduce the length of selection choices in the dropdown menu of WebForms

In my WebForms project, I have created a drop-down list by binding a list of data with 'Title' and 'Id' to it.

Ddltitlelist.DataSource = submissionTitleList;
Ddltitlelist.DataTextField = "Submission_Title";
Ddltitlelist.DataValueField = "Submission_Id";
Ddltitlelist.DataBind();

However, when the Title is too long, it affects the appearance of the drop-down. I attempted to manually set a max-width to the select options but this did not work.

My solution is to limit the width of the select options and add an ellipsis ("...") when the title exceeds that limit. Additionally, I plan to display the full title as a tooltip when hovering over an option. To implement this, the first step is to control the width of the select options.

It's always a challenge to provide solutions without reviewing your specific code, but one approach you can take is to restrict the text length in SQL queries. An example of this would be:

select Submission_Id,
Left(Submission_Title, 20) as Submission_Title
from Submission
where ....

Alternatively, you can adjust the text length after binding data and trim it accordingly.

For ASP.NET:

<asp:DropDownList ID="Ddltitlelist" runat="server"
    OnDataBound="Ddltitlelist_DataBound">
</asp:DropDownList>

In the Code-Behind:

protected void Ddltitlelist_DataBound(object sender, EventArgs e)
{
    foreach (ListItem li in Ddltitlelist.Items)
    {
        string text = li.Text;

        // Set tooltip on dropdown item
        li.Attributes.Add("title", text);
        
        // Trim text if longer than 20 characters
        if (text.Length > 20)
        {
            // Trim to 17 characters and add ellipsis
            li.Text = text.Substring(0, 17) + "...";
        }
    }
}
