Retrieving multiple items from listview

[mrithula8]

Hi When i used this, it says invalid static modifier for this item.So i used <pre>static int counter=0</pre> outside the method but im not able to select any item from listview.

Not sure how you have implemented it. i suggest declare the counter(static int counter = 0) not inside any methods. Just declare inside it inside the class. That would do... But how does this matter when selecting an item from the List View???? can you place the entire code block or atleast how you call this method after selecting the items.....???

Hi, I used this code in the selectedIndexchanged().Is this right?I declared the conuter variable inside the class.When i execute the code the form does not respond. <pre>private void listView1_SelectedIndexChanged(object sender, EventArgs e) { ListView.SelectedListViewItemCollection sl = this.listView1.SelectedItems; Label[] lb = new Label[4]; lb[0] = lb4; lb[1] = lb5; lb[2] = lb6; lb[3] = lb7; for (int h = 0; h < sl.Count;){ if(counter<lb.Length) { lb[counter].Text=sl[h].Text; counter++; } } }

Declare a label control array in the Form class like this

public Label[] lblArray = null;
static int counter = 0;

Inside the form load method add your labels like this.....

this.lblArray = new Label[] { label4, label5, label6 };

Then the event should look like this...

private void ListView1_SelectedIndexChanged_1(object sender, EventArgs e)
{
ListView.SelectedListViewItemCollection sl = ListView1.SelectedItems;

        for (int h = 0; h < sl.Count; h++)
        {
            if (counter < lblArray.Length)
            {
                lblArray\[counter\].Text = sl\[h\].Text;
                counter++;
            }
        }
    }

I have even checked this myself... Its working for me... without any problem...

hi I have another doubt.If i want to find the selected index of a listbox or a listview control i can use listbox.SelectedIndex; Similarly if i have 5 checkboxes and if i want to find the index of the checkbox that is checked how do i do this?There is no Selected Index property for checkbox. I have the exe files listed and each one is assigned a checkbox.I want to start only those exe files that i select.I am able to do this.After starting the exe files i want the client to send message to only those exe files that have been started. I used the following code to send message to different ports <pre>public void SendMessage() { try { label1.Text = "Enter the number of times to send the message:"; String ns = textBox1.Text; int c = Convert.ToInt32(ns); int[] a = new int[4]; XmlTextReader xtr1 = new XmlTextReader("p1.xml"); XmlTextReader xtr2 = new XmlTextReader("p2.xml"); XmlTextReader xtr3 = new XmlTextReader("p3.xml"); XmlTextReader xtr4 = new XmlTextReader("p4.xml"); int p1 = 0, p2 = 0, p3 = 0, p4 = 0; while (xtr1.Read()) { switch (xtr1.NodeType) { case XmlNodeType.Text: String rv = xtr1.Value; p1 = Convert.ToInt32(rv); break; } } while (xtr2.Read()) { switch (xtr2.NodeType) { case XmlNodeType.Text: String rv1 = xtr2.Value; p2 = Convert.ToInt32(rv1); break; } } while (xtr3.Read()) { switch (xtr3.NodeType) { case XmlNodeType.Text: String rv2 = xtr3.Value; p3 = Convert.ToInt32(rv2); break; } } while (xtr4.Read()) { switch (xtr4.NodeType) { case XmlNodeType.Text: String rv3 = xtr4.Value;

you can use the same slvi to get that. slvi[index].checked will give you the corresponding checkbox of an item is checked or not.....
