Return List<> from user control & bind to parent page grid.

zeego

Hi, I want to return selected items (check box list) on button click of a user control to the parent page. How do I do this ? The checked items would be in form of List<>. I have made the user control but don't know how to pass an input id to it to fetch the records and on button click, return them.

Just make one public method of your user control which returns List<> items [Contains selected items]. That's it. You need to access that particular method once button click is over. HTH

Update: Ok, I created two public properties, now I want to return the selected checkbox items in the checkbox list and return them on button click so I used a foreach, not much sure about my approach.Here is how its looking now. How to bind the results with parent page gridview on user control button click ?

public partial class assets_WebControls_ftExclusions : System.Web.UI.UserControl
{
private int id; // the id passed from parent page
private ftExclusionsList myftExclusions; // the list to return to master page

public  int ID
{
    get{return ID;}
    set{ID=value;}
}

public ftExclusionsList selectedExclusions
{
    get { return myftExclusions; }
    set { myftExclusions = value; }
}

protected void Page\_Load(object sender, EventArgs e)
{

// Just binding the checkbox list with selected items/total items
if (!Page.IsPostBack)
{
cblExclusions.DataBind();
ftExclusionsList myExcluList = ftExclusionsManager.ftExclusionsById(ID);
if (myExcluList != null)
{
if (myExcluList.Count > 0 && myExcluList != null)
{
foreach (ftExclusions ex in myExcluList)
{
cblExclusions.Items.FindByValue(ex.excluId.ToString()).Selected = true;
}
}
}
}

}
protected void btnUpdate\_Click(object sender, EventArgs e)
{// returning result set here how to bind it with gridview on parent page ? :( 
    ftExclusionsList myFTExclusionList = new ftExclusionsList();
    foreach (ListItem li in cblExclusions.Items)
    {
        if (li.Selected == true)
        {
            ftExclusions myftExclusion = new ftExclusions();
            myftExclusion.ftExcluId = Convert.ToInt32(li.Value);
            myftExclusion.excludesc = li.Text.ToString();
            myFTExclusionList.Add(myftExclusion);
        }
        
    }
    selectedExclusions = myFTExclusionList;
}

}
