I want to find the Parent Repeater, which contains Child Repeater and Child Repeater contains dropdownlist. On SelectedIndexChange of the Drowndownlist I want to find out the Parent Repeater. After finding the parent repeater, I want to find the hiddenfield value inside Parent Repeater. i.e.
Parent Repeater Contains HiddenField and Child Repeater Child Repeater contains Dropdownlist on this dropdown selected index change event I want to find HiddenField value which is in Parent Repeater.
My Code:
DropDownList myGeneralButton = (DropDownList)sender;
Repeater item = (Repeater)myGeneralButton.Parent.Parent;
for (int i = 0; i < item.Items.Count; ++i)
{
HiddenField hdn= item.Items[i].FindControl("Hdhotelname") as HiddenField;
string h = hdn.Value;
}
In this hidden field I am getting all the values, but I want a value of that particular index where I am selecting selecting the dropdown.
Thanks
You have to search through the DropDownList's NamingContainer. The flow should be like this:
(DropDownList)sender
--> NamingContainer(Child RepeaterItem)
--> NamingContainer(Child Repeater)
--> NamingContainer(Parent RepeaterItem)
--> FindControl"Hdhotelname" (Hdhotelname)
and your code should be like this:
protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
var ddl = (DropDownList)sender;
var rptChild = ddl.NamingContainer.NamingContainer;//Child Repeater
if (rptChild != null)
{
var rptParentItem = rptChild.NamingContainer;//Parent RepeaterItem
var hdnfld = rptParentItem.FindControl("Hdhotelname") as HiddenField;
if (hdnfld != null)
{
//Do your tasks
}
}
}
Hope it helps!
