Re: persist dropdown list selected value across content pages of master page

Hi Nitin,

If you want to accomplished it, you could define a base class BasePage that herits from Page, then make your content page inherits from it and override relate methods.

for example :

BasePsge .cs

public class BasePage :Page
{
    public virtual string SayHello()
    {
        return "This is basepage information！";
    }
}

the code behind of master page:

BasePage currentPage = null;
    protected void Page_Load(object sender, EventArgs e)
    {
        currentPage = Page as BasePage;
    }

    protected void CallContentMethod_Click(object sender, EventArgs e)
    {
        if (currentPage != null)
        {
            welcomeMessage.Text = currentPage.SayHello();
        }
    }

the code behind of content page

default.cs

public partial class Template_Default : BasePage

    public override string SayHello()
    {
        return "This content page information！";
    }

Hope it helps!!

Within the DropDownList.SelectedIndexChanged event, you could simply set a cookie or a Session variable to your SelectedValue. Then, within the DropDownList.DataBound event, I'd check for the existence of this cookie or Session variable, and set the DropDownList.SelectedValue accordingly.

Hi All,

I have a dropdown control in the master page in my project. The content pages are dependent on the value selected in the dropdown control.

The problem is if the dropdown is selected in one page do not retains it's value while navigating to other content pages

I need to keep the selected value persistent across the content pages. Does somebody know how to accomplished this.

Thanks in advance,

Nitin
