hi

I have a gridview with 3 column Sno, Name and age. Sno i am fetching from Database and in name and age column I just placed a textbox where user can enter them.
and i page load i am selecting first row and changing the background color too.
now when he moves to next row by mouse click i want the next row to be highlighted and insertable. and after entering all rows i want to save them at once.

i tried different codes for this but not working properly.

C#

protected void Page_Load(object sender, EventArgs e)
    {

        lQry = "Select SNo from sample";
        ds = clsGen.GetData(lQry);
        GridviewSample.DataSource = ds;
        GridviewSample.DataBind();
        if (!IsPostBack)
        {
            GridviewSample.SelectedIndex = 0;
            //GridviewSample.Rows[0].BackColor = System.Drawing.Color.LightGreen;
        }
    }

C#

protected void GridviewSample_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
  {
      GridviewSample.Rows[GridviewSample.SelectedIndex].BackColor = System.Drawing.Color.LightGray;
  }

C#

protected override void Render(System.Web.UI.HtmlTextWriter writer)
   {
       foreach (GridViewRow row in GridviewSample.Rows)
       {
           if (row.RowType == DataControlRowType.DataRow)
           {
               row.Attributes["onmouseover"] =
                  "this.style.cursor='hand';this.style.textDecoration='underline';";
               row.Attributes["onmouseout"] =
                  "this.style.textDecoration='none';";
               // Set the last parameter to True
               // to register for event validation.
               row.Attributes["onclick"] =
                ClientScript.GetPostBackClientHyperlink(GridviewSample,
                   "Select$" + row.DataItemIndex, true);
           }
       }
       base.Render(writer);
   }

protected void GridviewSample_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState)5)
            {
                TextBox t1 = (TextBox)e.Row.Cells[1].Controls[0];
                TextBox t2 = (TextBox)e.Row.Cells[2].Controls[0];
                if (t1 != null & t2 != null)
                {
                    t1.Attributes.Add("onmouseover", "this.originalstyle=this.style.backgroundColor;this.style.backgroundColor='#DDDDDD'");
                    t1.Attributes.Add("onmouseout", "this.style.backgroundColor=this.originalstyle");


                    t2.Attributes.Add("onmouseover", "this.originalstyle=this.style.backgroundColor;this.style.backgroundColor='#DDDDDD'");
                    t2.Attributes.Add("onmouseout", "this.style.backgroundColor=this.originalstyle");
                }
            }
        }
    }

Solution 1

You can use and change according to the requirement by adjusting SelectedRowStyle property of the Gridview.

This code is working fine to change the selected row color but the problem is i can't enter anything in the textboxes of selected row, please help.

protected override void Render(System.Web.UI.HtmlTextWriter writer)
{
foreach (GridViewRow row in GridviewSample.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
row.Attributes["onmouseover"] =
"this.style.cursor='hand';this.style.textDecoration='underline';";
row.Attributes["onmouseout"] =
"this.style.textDecoration='none';";
// Set the last parameter to True
// to register for event validation.
row.Attributes["onclick"] =
ClientScript.GetPostBackClientHyperlink(GridviewSample,
"Select$" + row.DataItemIndex, true);
}
}
base.Render(writer);
}
