C# - Call a Function from other script

Hi everyone i wrote a SoketServer with C# 2005 Express for my explication and its work fine .

when i revise a message in Soket.cs script , i realize it and call this functio开发者_StackOverflow社区n in mainform.cs .

public void AdverFilter(string value)
    {
      MessageBox.Show("Adver"+value);
      this.adverBindingSource.Filter = "store_index Like '*" + value + "*'";
      //MessageBox.Show(this.adverBindingSource.Filter);
    }

message box show true filter value but adverbindingsourse dont filter my table...

Note : i create button and wrote this code and click it after AdverFilter function start but its show non value for adver filter...

private void button3_Click(object sender, EventArgs e)
    {
      MessageBox.Show(this.adverBindingSource.Filter);
    }

Check the SupportsFiltering property to see if the BindingSource can actually do filtering.
