刪除網格視圖中的特定行

在下面的代碼中，我有網格視圖，其中有6列，其中有1 dropdown和5 textbox。我的目標是刪除特定的行。我試過但我可以無法刪除特定的行。刪除網格視圖中的特定行

protected void gvInvoice_RowDeleting(object sender, GridViewDeleteEventArgs e) 
{ 

    DataTable dtCurrentTable = new DataTable(); 
    int RowIndex = e.RowIndex; 
    dtCurrentTable = (DataTable)ViewState["CurrentTable"]; 
    dtCurrentTable.Rows.RemoveAt(e.RowIndex); 

    SetPreviousData1(dtCurrentTable); 


} 
private void SetPreviousData1(DataTable dtCurrentTable) 
{ 
    int rowIndex = 0; 
    if (dtCurrentTable != null) 
    { 
     DataTable dt = dtCurrentTable; 
     if (dt.Rows.Count > 0) 
     { 
      for (int i = 0; i < dt.Rows.Count; i++) 
      { 
       Label lblProductID = (Label)gvInvoice.Rows[rowIndex].Cells[1].FindControl("lblProductID_i"); 
       DropDownList txtProductName = (DropDownList)gvInvoice.Rows[rowIndex].Cells[2].FindControl("EditableddlProductName"); 
       TextBox txtQuantity = (TextBox)gvInvoice.Rows[rowIndex].Cells[3].FindControl("txtQuantity"); 
       TextBox txtProductPrices = (TextBox)gvInvoice.Rows[rowIndex].Cells[4].FindControl("lblProductPrices"); 
       TextBox txtProfitPrice = (TextBox)gvInvoice.Rows[rowIndex].Cells[5].FindControl("txtProfitPrice"); 
       TextBox txtTaxCalculation = (TextBox)gvInvoice.Rows[rowIndex].Cells[6].FindControl("txtTaxCalculation"); 
       TextBox txtTotaPrice = (TextBox)gvInvoice.Rows[rowIndex].Cells[7].FindControl("txtTotaPrice"); 

       lblProductID.Text = dt.Rows[i]["Column1"].ToString(); 
       txtProductName.Text = dt.Rows[i]["Column2"].ToString(); 
       txtQuantity.Text = dt.Rows[i]["Column3"].ToString(); 
       txtProductPrices.Text = dt.Rows[i]["Column4"].ToString(); 
       txtProfitPrice.Text = dt.Rows[i]["Column5"].ToString(); 
       txtTaxCalculation.Text = dt.Rows[i]["Column6"].ToString(); 
       txtTotaPrice.Text = dt.Rows[i]["Column7"].ToString(); 

       rowIndex++; 
      } 
     } 
    } 
}

我想你需要再次綁定gridview數據源。

gvInvoice.DataSource = dtCurrentTable; 
    gvInvoice.DataBind()

地方刪除的數據表

謝謝它運作良好 – Thiyagu

您刪除在GridView的行，但隨後你會並再次調用數據綁定這是剛剛刷新GridView控件相同的狀態，原來的數據源是此代碼後in。

將其從數據源中刪除，然後將數據綁定或數據綁定從gridview中刪除而不進行重新綁定。

protected void gvInvoice_RowDeleting(object sender, GridViewDeleteEventArgs e) 
    { 
     myobj.myconnection();// connection created 
     string mystr = "Delete table_name where water_id= '" + gvInvoice.DataKeys[e.RowIndex].Value + "'";// query 
     sqlcmd = new SqlCommand(mystr, myobj.mycon); 
     sqlcmd.ExecuteNonQuery(); 
     fillgrid(); 
    }
