I tried to save rows in listview control in database but i am not able to loop through each row. My listview is multicolumn, it have 4 column. I tried for loop:

for (int i = 0; i < listview.Items.Count; i++)
{
String abc = listview.Items[i].Subitem[i].Text;
//other varables
}

But it is not working and giving error. So what is the best way to iterate Listview items in WPF. Basically i add rows when i run my app otherwise there is nothing in it.

Onclick Add Method for Listview:

I create a class name AddList and its default constructor gets 4 argument. Like
AddList ad = new AddList("1","3","2","5");
So when i click on add button:

void private addBtn_Onclick(default arguments..........){
listview.Items.Add(ad);
}

Now i want to save all added items in listview in DB. I am using SQL Server. That is why i need to loop each item in listview to insert each item in DB one by one.

I add item with a button with onclick event. listview.items.Add("Add") etc. And items successfully add and i can see items added in Listview. Only issue is that how i can each column and rows value with loop. I found many sites which uses ListviewItem object to loop listview items and subitem and some uses for loop. I tried both foreach and for loop but error is coming. Basically i want to save item value in string so i use String abc = listview.items[i].Text; inside a loop. Error is coming on .Text and on type of variable. I am using WPF C#

Solution 1

try like below

C#

for (int i = 0; i < listview.Items.Count; i++)
{
    AddList item  = listview.Items[i] as AddList;
    // then you can access properties of item.PropertyName
}

.Text is underlined with red color and also gives error on string type and say it doesnt support string bcz its a object

VS2013 not showing Text property of listview instead it is showing TextInput, that is why it is giving error

i dont want to add them. They already added in listview. I want to retrieve each item one by one. And by the way listview.Items[i] and listview.Items[i].SubItem[0] is not working
