gridview始终插入模式 [英] gridview always insert mode

问题描述

hi



我有一个带有3列Sno，名称和年龄的gridview。 Sno我从数据库中获取，在名称和年龄列中，我只是放置了一个文本框，用户可以在其中输入它们。

和i page load我正在选择第一行并更改背景颜色。

现在当他通过鼠标点击移动到下一行时我希望下一行突出显示并可插入。在输入所有行后我想立即保存它们。



i为此尝试了不同的代码但工作不正常。

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.

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;
        }
    }

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

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");
                }
            }
        }
    }

+ row.DataItemIndex， true ）;
}
}
base .Render（writer）;
}

" + row.DataItemIndex, true); } } base.Render(writer); }

您可以使用和更改根据要求调整Gridview的 SelectedRowStyle 属性。



谢谢

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