Did you try label1.Text = item.SubItems[1].Text or label3.Text = item.SubItems[3].Text?

Solution 2

There is a property for this:

Additional documentation information can be found here[^].

I modified your code sample a bit:

C#

int searchIndex = 0; //Use a counter to know on which row you currently are
foreach (ListViewItem item in listview1.Items)
    {
        if (item.SubItems[2].Text == name.Text)
        {//If text is found, select row at the current index
           listview1.Items[searchIndex].Selected = true;
           label1.Text = item.SubItems[0].Text;
           label2.Text = item.SubItems[1].Text;
           label3.Text = item.SubItems[2].Text;
        }
        else
        {//If text is not found, deselect row at the current index
            listview1.Items[searchIndex].Selected = false;
        }
        //afterwards, increase searchIndex ++1
        searchIndex++;
    }

How does your solution assign values to the label as asked in the question?
What is the point of having that "searchIndex"?

Marco Bertschi 17-Mar-13 9:23am

I have now added the assignement of the labels.
The searchIndex counts which row of the ListView we are currently searching, afterwards we can select the corresponding row at the searchIndex.

You do not need a variable to keep the index of selected row in listView. List view already has aselected items collection. Assuming that only one item is selected, getting that index will be:

if (listView1.SelectedItems.count > 0)
{
ListViewItem selectedItem = listView1.SelectedItems[0];
}

In the case like above, it should be using for loop instead of foreach.

for(int index = 0; index <listview1.Items.count; index++)
{
if (listview1.Items[index].SubItems[2].Text.Equals(name.Text))
{
//If text is found, select row at the current index
listview1.Items[index].Selected = true;
label1.Text = listview1.Items[index].SubItems[0].Text;
label2.Text = listview1.Items[index].SubItems[1].Text;
label3.Text = listview1.Items[index].SubItems[2].Text;
}
else
{
//If text is not found, deselect row at the current index
listview1.Items[index].Selected = false;
}
}

Right. I just not wanted to modify the code too much because IDK what around the code snippet happens.

In your ListView "Name" Column is second Column so its index is 1.

C#

foreach (ListViewItem item in listView1.Items)
     {
         if (!string.IsNullOrEmpty(item.Text))//Check Item value is not Null or Empty
         {
             if (item.SubItems[1].Text == name.Text)
             {
                 label1.Text = item.SubItems[0].Text;
                 label2.Text = item.SubItems[1].Text;
                 label3.Text = item.SubItems[2].Text;
             }
         }

      }

Please do not write things like "If u got ur Answer pls mark it." into your solution.
It is very impolite and we do not like to see it on CP.
I removed the bit of begging now.

In addition, what do you do when the searched item is suddenly at index 0?
