如何将gridview行添加到datatable？ [英] How to add gridview rows to a datatable?

问题描述

我有一个gridview，它将包含一些'n'行的数目....现在我想添加gridview的所有行到将用于批量复制操作的数据表...

我发现这个 http：//www.codeproject .com / KB / aspnet / GridView_To_DataTable.aspx

但是我希望将gridview的所有列添加到datatable
的数据行中网格http://img85.imageshack.us/img85/4044/gridp.jpg

我要将gridview转换为datatable在submit ....任何建议...

编辑：

下面的回答正常，我也找到了一个答案...

  DataTable dt = new DataTable（）; 
 dt.Columns.Add（new DataColumn（EmpId，typeof（Int64）））; 
 dt.Columns.Add（new DataColumn（FromDate，typeof（DateTime）））; 
 dt.Columns.Add（new DataColumn（ToDate，typeof（DateTime）））; 
 dt.Columns.Add（new DataColumn（DaysPresent，typeof（double）））; 
 dt.Columns.Add（new DataColumn（OpeningAdvance，typeof（double）））; 
 dt.Columns.Add（new DataColumn（AdvanceDeducted，typeof（double）））; 
 dt.Columns.Add（new DataColumn（RemainingAdvance，typeof（double）））; 
 dt.Columns.Add（new DataColumn（SalaryGiven，typeof（double）））; 
 dt.Columns.Add（new DataColumn（CreatedDate，typeof（DateTime）））; 
 
 foreach（GridEmployee.Rows中的GridViewRow行）
 {
 if（row.RowType == DataControlRowType.DataRow）
 {
 DataRow dr = dt .NewRow（）; 
 dr [EmpId] = Convert.ToInt64（（（HiddenField）row.Cells [0] .FindControl（HiddenId））。 
 dr [FromDate] = Convert.ToDateTime（GetMonthNumberFromAbbreviation（fromdate [1] .ToString（））+'/'+ fromdate [0] .ToString（）+'/'+ fromdate [2] .ToString （））; 
 dr [ToDate] = Convert.ToDateTime（GetMonthNumberFromAbbreviation（todate [1] .ToString（））+'/'+ todate [0] .ToString（）+'/'+ todate [2] .ToString （））; 
 dr [DaysPresent] = Convert.ToDouble（（（TextBox）row.Cells [3] .FindControl（TxtDaysPresent））。 
 dr [OpeningAdvance] = Convert.ToDouble（（（TextBox）row.Cells [4] .FindControl（txtOpeningAdv））。 
 dr [AdvanceDeducted] = Convert.ToDouble（（（TextBox）row.Cells [5] .FindControl（TxtAdvanceDeducted））。 
 dr [RemainingAdvance] = Convert.ToDouble（（（TextBox）row.Cells [6] .FindControl（TxtClosingAdvance））。 
 dr [SalaryGiven] = Convert.ToDouble（（（TextBox）row.Cells [7] .FindControl（TxtSalary））。 
 dr [CreatedDate] = Convert.ToDateTime（System.DateTime.Now.ToString（））; 
 dt.Rows.Add（dr）; 
} 
} 
 SqlBulkCopy sbc = new SqlBulkCopy（connectionString）; 
 sbc.DestinationTableName =SalaryDetails; 
 sbc.ColumnMappings.Add（EmpId，EmpId）; 
 sbc.ColumnMappings.Add（FromDate，FromDate）; 
 sbc.ColumnMappings.Add（ToDate，ToDate）; 
 sbc.ColumnMappings.Add（DaysPresent，DaysPresent）; 
 sbc.ColumnMappings.Add（OpeningAdvance，OpeningAdvance）; 
 sbc.ColumnMappings.Add（AdvanceDeducted，AdvanceDeducted）; 
 sbc.ColumnMappings.Add（RemainingAdvance，RemainingAdvance）; 
 sbc.ColumnMappings.Add（SalaryGiven，SalaryGiven）; 
 sbc.ColumnMappings.Add（CreatedDate，CreatedDate）; 
 sbc.WriteToServer（dt）; 
 sbc.Close（）; 
  

解决方案

可以逐行遍历datagrid，并进行逗号分离文件。然后使用批量插入或bcp将数据插入数据库。

另一个解决方案

  DataTable dt = new DataTable（）; 
 for（int j = 0; j< grdList.Rows.Count; j ++）
 {
 DataRow dr; 
 GridViewRow row = grdList.Rows [j]; 
 dr = dt.NewRow（）; （int i = 0; i< row.Cells.Count; i ++）
 {
 dr [i] = row.Cells [i] .Text; 
} 
 
 dt.Rows.Add（dr）; 
} 
 
 SqlBulkCopy sbc = new SqlBulkCopy（targetConnStr）; 
 sbc.DestinationTableName =yourDestinationTable; 
 sbc.WriteToServer（dt）; 
 sbc.Close（）; 
  

I have a gridview which will contain some 'n' number of rows.... Now i want to add all rows of the gridview to a datatable which will be used for bulkcopy operation...

I have found this http://www.codeproject.com/KB/aspnet/GridView_To_DataTable.aspx

But i want all columns of my gridview to be added to the datarow of the datatable Grid http://img85.imageshack.us/img85/4044/gridp.jpg

I want to convert gridview to datatable on submit.... Any suggestion...

EDIT:

Answer below works and i have found an answer too...

    DataTable dt = new DataTable();
    dt.Columns.Add(new DataColumn("EmpId", typeof(Int64)));
    dt.Columns.Add(new DataColumn("FromDate", typeof(DateTime)));
    dt.Columns.Add(new DataColumn("ToDate", typeof(DateTime)));
    dt.Columns.Add(new DataColumn("DaysPresent", typeof(double)));
    dt.Columns.Add(new DataColumn("OpeningAdvance", typeof(double)));
    dt.Columns.Add(new DataColumn("AdvanceDeducted", typeof(double)));
    dt.Columns.Add(new DataColumn("RemainingAdvance", typeof(double)));
    dt.Columns.Add(new DataColumn("SalaryGiven", typeof(double)));
    dt.Columns.Add(new DataColumn("CreatedDate", typeof(DateTime)));

    foreach (GridViewRow row in gridEmployee.Rows) 
    {
        if (row.RowType == DataControlRowType.DataRow)
        {
            DataRow dr = dt.NewRow();
            dr["EmpId"] = Convert.ToInt64(((HiddenField)row.Cells[0].FindControl("HiddenId")).Value);
            dr["FromDate"] = Convert.ToDateTime(GetMonthNumberFromAbbreviation(fromdate[1].ToString()) + '/' + fromdate[0].ToString() + '/' + fromdate[2].ToString());
            dr["ToDate"] = Convert.ToDateTime(GetMonthNumberFromAbbreviation(todate[1].ToString()) + '/' + todate[0].ToString() + '/' + todate[2].ToString());
            dr["DaysPresent"] = Convert.ToDouble(((TextBox)row.Cells[3].FindControl("TxtDaysPresent")).Text);
            dr["OpeningAdvance"] = Convert.ToDouble(((TextBox)row.Cells[4].FindControl("txtOpeningAdv")).Text);
            dr["AdvanceDeducted"] = Convert.ToDouble(((TextBox)row.Cells[5].FindControl("TxtAdvanceDeducted")).Text);
            dr["RemainingAdvance"] = Convert.ToDouble(((TextBox)row.Cells[6].FindControl("TxtClosingAdvance")).Text);
            dr["SalaryGiven"] = Convert.ToDouble(((TextBox)row.Cells[7].FindControl("TxtSalary")).Text);
            dr["CreatedDate"] = Convert.ToDateTime(System.DateTime.Now.ToString());
            dt.Rows.Add(dr);
        }
    }
    SqlBulkCopy sbc = new SqlBulkCopy(connectionString);
    sbc.DestinationTableName = "SalaryDetails";
    sbc.ColumnMappings.Add("EmpId", "EmpId");
    sbc.ColumnMappings.Add("FromDate", "FromDate");
    sbc.ColumnMappings.Add("ToDate", "ToDate");
    sbc.ColumnMappings.Add("DaysPresent", "DaysPresent");
    sbc.ColumnMappings.Add("OpeningAdvance", "OpeningAdvance");
    sbc.ColumnMappings.Add("AdvanceDeducted", "AdvanceDeducted");
    sbc.ColumnMappings.Add("RemainingAdvance", "RemainingAdvance");
    sbc.ColumnMappings.Add("SalaryGiven", "SalaryGiven");
    sbc.ColumnMappings.Add("CreatedDate", "CreatedDate");
    sbc.WriteToServer(dt);
    sbc.Close();

解决方案

you can traverse datagrid row by row and make a comma separated file. then use Bulk insert or bcp for inserting data to db.

Another Solution

    DataTable dt = new DataTable();    
    for (int j = 0; j < grdList.Rows.Count; j++)
    {
        DataRow dr;
        GridViewRow row = grdList.Rows[j];
        dr = dt.NewRow();
        for (int i = 0; i < row.Cells.Count; i++)
        {
            dr[i] = row.Cells[i].Text;
        }

        dt.Rows.Add(dr);
    }

SqlBulkCopy sbc = new SqlBulkCopy(targetConnStr);
sbc.DestinationTableName = "yourDestinationTable";
sbc.WriteToServer(dt);
sbc.Close();
