Binding only one column

Setting text property of Tabs as follows:

In the code below , GetQuesType() returns a complete QuesType named Table so the Tabs generated by the code below are like equal to the no. of records in the table. What I want is that ONLY QuesType column be binded to the Tabs. What should I change in my code?

aspx page:

**<div id="div1" runat="server">
        <telerik:RadTabStrip ID="RadTabStrip1" runat="server" MultiPageID="RadMultiPage1">
        </telerik:RadTabStrip>
        <telerik:RadMultiPage ID="RadMultiPage1" runat="server" Width="100%">
            <telerik:RadPageView ID="pv1" runat="server" Selected="true">

            </telerik:RadPageView>
        </telerik:RadMultiPage>
    </div>**

I have followed this example:

{EDIT}

Modified the method as follows:

private void CreateRootTab(DataSet ds)
    {
        for (int i = 0; i < ds.Tables[0].Columns.Count; i++)
        {
            var tab = new RadTab();
            tab.Text = (string) ds.Tables[0].Rows["QuesType"].ItemArray[i];//PROBLEM AREA
            RadTabStrip1.Tabs.Add(tab);
        }
    }

Now it says: The best overloaded method match for 'System.Data.DataRowCollection.this[int]'开发者_运维技巧 has some invalid arguments

How else should I bind the tabs with QuesType column?

ok it should have been this:

tab.Text = ds.Tables[0].Rows[0]["QuesType"].ItemArray[i].ToString();

Now its giving error on itemArray

'object' does not contain a definition for 'ItemArray' and no extension method 'ItemArray' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)


The default type returned by a row column is Object. You need to cast the column returned by this statement...

ds.Tables[0].Rows[0]["QuesType"]

...to the appropriate type before calling ItemArray[0]. A quick and dirty way to do this is...

tab.Text = ((QuesType)ds.Tables[0].Rows[0]["QuesType"]).ItemArray[0];

However, a more robust, and less error-prone solution would be...

if (ds.Tables.Count > 0)
{
    var table = ds.Tables[0];
    var columnName = "QuesType";
    if (table.Rows.Count > 0 && table.Columns.Contains(columnName))
    {
        var tableRow = table.Rows[0];
        var quesType = tableRow.Field<QuesType>(columnName);
        if (quesType != null && quesType.ItemArray.Count() > 0)
        {
            tab.Text = quesType.ItemArray[0];
        }
    }
}

I hope that helps!
