How to Create custom gridview control?

Question

Can anyone help me in creating Custom GridView Control in c# .Net?

Answer 1

We'd need to know something about what you wanted your GridView to support that isn't possible in the standard one.

Answer 2

Here's a blog post and a code sample (from one of my projects) that may give you what you need.

ASP.NET 2.0 - Extending GridView control to display extra Footer Rows

public class MyGridView : GridView
{
    protected GridViewRow _footerRow = null;

    public override GridViewRow FooterRow
    {
        get
        {
            if (_footerRow == null)
            {
                return base.FooterRow;
            }
            else
            {
                return _footerRow;
            }
        }
    }
    public MyGridView()
    {
    }

    protected override int CreateChildControls(System.Collections.IEnumerable dataSource, bool dataBinding)
    {
        ...


        ...
    }



    [System.ComponentModel.Category("Behavior")]
    [Themeable(true)]
    [System.ComponentModel.Bindable(System.ComponentModel.BindableSupport.No)]
    public bool ShowHeaderWhenEmpty
    {
        get
        {
            if (this.ViewState["ShowHeaderWhenEmpty"] == null)
            {
                this.ViewState["ShowHeaderWhenEmpty"] = false;
            }

            return (bool)this.ViewState["ShowHeaderWhenEmpty"];
        }
        set
        {
            this.ViewState["ShowHeaderWhenEmpty"] = value;
        }
    }

    [System.ComponentModel.Category("Behavior")]
    [Themeable(true)]
    [System.ComponentModel.Bindable(System.ComponentModel.BindableSupport.No)]
    public bool ShowFooterWhenEmpty
    {
        get
        {
            if (this.ViewState["ShowFooterWhenEmpty"] == null)
            {
                this.ViewState["ShowFooterWhenEmpty"] = false;
            }

            return (bool)this.ViewState["ShowFooterWhenEmpty"];
        }
        set
        {
            this.ViewState["ShowFooterWhenEmpty"] = value;
        }
    }
}
