I tried my best to make the retrieved data from a table to lower and show in listbox1. The ToLOwer() is not working as like in DDL. Can any help?
My code:

C#

adds1.Add("SELECT");
            for (int i = 0; i < ds1.Tables[0].Rows.Count; i++)
            {

                adds1.Add(ds1.Tables[0].Rows[i].ItemArray[0].ToString());
                name1 = ds1.Tables[0].Rows[i]["block_name"].ToString().ToLower();
                v_proceed_tag = "";

            }
            ListBox1.DataSource = adds1;
            ListBox1.DataBind();
            ListBox1.Visible = true;

In DDL?
ToLower not working?
How that?
Please elaborate your question a little bit more, I can not figure out, what your problem is, and what this code should do exactly.
By the way, you can even lowercase in the query itself, if you don't know any better: http://msdn.microsoft.com/en-us/library/ms174400.aspx

Hi,

in DDL (SQL Server) there is no function named toLower() function is Lower([Column Name])

in your case you can try this

adds1.Add(ds1.Tables[0].Rows[i].ItemArray[0].ToString().ToLower());

but don't use Index while fetching data from DataTable or DataSet because its erroneous use Column Name or Table Name.

Thanks

Try:

C#

adds1.Add("SELECT");
            for (int i = 0; i < ds1.Tables[0].Rows.Count; i++)
            {

                adds1.Add(ds1.Tables[0].Rows[i].ItemArray[0].ToString().ToLower());
                name1 = ds1.Tables[0].Rows[i]["block_name"].ToString().ToLower();
                v_proceed_tag = "";

            }
            ListBox1.DataSource = adds1;
            ListBox1.DataBind();
            ListBox1.Visible = true;
