Populating a ComboBox

[matt23lucier]

I have a combo box that I am populating. I fill the comboBox alrite but the string that diplays in the combobox is not what I want. Here is my code:
for(int i =0; i < dt.Rows.Count; i++)
{
cmb.Items.Add(new recordClass(dt.Rows["RecordType"].ToString(), Convert.ToInt32(dt.Rows["RecordId"])));
}

Inside the combobox is reading: trackingsytem.RecordClass
- I want the contents of dt.Rows["RecordType"] to appear in the combobox. Any help would be appreciated.

dt.Rows["RecordType"]

Then why don't you put this:

for(int i =0; i < dt.Rows.Count; i++)
{
cmb.Items.Add(dt.Rows[i]["RecordType"].ToString());                    
}

or

        cmb.DataTextField = "RecordType";
        cmb.DataValueField = "RecordID";
        cmb.DataSource = dt;
        cmb.DataBind();

[b]cmb.Items.Add(new recordClass(dt.Rows[i]["RecordType"].ToString(), ...[/b]

You're adding the recordClass object itself. The default method, recordClass.ToString(), returns the class name, hence the "error" you have when the item is finally rendered.

On your implementation of recordClass type, override ToString() to return the required field instead

public override string ToString() {
    return someVar;
}

Or call the appropriate recordClass field/property that you want to add on the combobox.

 

[stnkyminky]

your recordClass exposes a public property that returns the value for dt.Rows["RecordType"]...right?

right below in the call to "InitializeComponent()", you need to insert the following:

cmb.DisplayMember = "" <---- public Property name goes here.



This will solve your problem.
