Question

How do you get the outer repeater item from an inner repeater. My outer repeater datasource has 3 items. My inner repeater datasource has 7 items. When I am iterating inside the inner repeater how do I get an item from the outer repeater?

My outer repeater datasource is a generic list. One of the items in this list is a day (in number format). My inner repeater is a list of int, 1 through 7 in this list. I need some logic so that when I am iterating the list of days (in the inner)…..if the outer has a value of 2 on the current recorded being iterated (so there is a match) I print something.

I hope that makes sense…

Thanks for any help or tips provided.

What I usually do is just catch the outer item on databound and save it to a variable on the page. Here I have two consecutive repeaters. I save the year from the first repeater and then can reference it when I’m binding the second one.

    protected void repAnnualReport_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        CurrentYear = int.Parse(((Literal)e.Item.FindControl("litLicenseYear")).Text);

        Repeater repLicenseLengths = (Repeater)e.Item.FindControl("repLicenseLengths");
        repLicenseLengths.DataSource = GetLicenseLengths(CurrentYear);
        repLicenseLengths.DataBind();
    }

    protected void repLicenseLengths_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        CurrentLength = int.Parse(((Literal)e.Item.FindControl("litLicenseLength")).Text) * 365;

        Repeater repMonthlyReport = (Repeater)e.Item.FindControl("repMonthlyReport");
        repMonthlyReport.DataSource = new object[12];
        repMonthlyReport.DataBind();
    }

If what your binding to the first repeater is an class list or queryable, you can access the individual item like this in the first line.

SaveCurrentItem = (CurrentItemClass)e.Item.DataItem;
