Answer 1

for(int i=0; i< gridview.RowCount; i++)
{
    GridData rowData = gridview.GetRow(i) as GridData;
}GridData是你绑的数据对象

朋友啊，我这个gird 是基于gridControl

Answer 4

好像就是GetDataRow

Answer 5

GetDataRow这个方法有个int类型的参数

Answer 6

要获取所有行，你直接访问DataSource属性即可，那个是原始数据源，如果传递的是List<T>，你得到的就是该List<T>对象，如果传递的是DataTable，那么GridControl的DataSource就是那个DataTable，而GridView的DataSource属性则是其DefaultView

private void btnAdd_Click(object sender, EventArgs e)
        {
            this.EndEdit();            DataTable dtMaster = this.mClientBLData.DsData.Tables[0];
            bool cbChecked = false;
            int blAdd = 0;            #region
            for (int i =gridView1.RowCount - 1; i >= 0; i--)
            {
                DataRow dgr = gridView1.GetDataRow(i);
                cbChecked = dgr["Column1CbSelect"] == null ? false : (bool)(dgr["Column1CbSelect"]);                if (cbChecked == true)
                {
                    blAdd = 0;
                   for (int j = 0; j < gridView2.RowCount; j++)
    {
                        DataRow dgr2 = gridView1.GetDataRow(j);
                if (dgr2["Column2ProdID"].ToString().Trim() == 
                                  dgr["Column1ProdID"].ToString().Trim())
                        {
                            blAdd = blAdd + 1;
                        }
        } 
                    
                    if (blAdd == 0)
                    {
                        DataRow dr = dtMaster.NewRow();
                        if (dr != null)
                        {
                        dr["CompanyID"] =this.mClientApp.CurrentUserInfo.CompanyID;
                            dr["prodID"] = dgr["Column1ProdID"];
                            dr["prodCode"] = dgr["Column1ProdCode"];
                            dr["prodName"] = dgr["Column1ProdName"];
                            dr["prodSpecName"] = dgr["Column1ProdSpec"];
                            dr["Disabled"] = false;
                            dr["ProdCode_UD"] = string.Empty;
                            dr["ProdCode_SAP"] = dgr["Column1ProdCode_SAP"];
                            dr["BaseUnit"] = dgr["Column1BaseUnit"];
                            dr["wgtUnit"] = dgr["Column1WgtUnit"];
                            dr["wgtUnitRate"] = dgr["Column1WgtUnitRate"];
                            dr["AuxUnit"] = dgr["Column1AuxUnit"];
                            dr["AuxUnitRate"] = dgr["Column1AuxUnitRate"];
                            dr["MinUnit"] = dgr["Column1MinUnit"];
                            dr["MinUnitRate"] = dgr["Column1MinUnitRate"];
                            dr["TaxRateCode"] = dgr["Column1TaxRateCode"];                            dtMaster.Rows.Add(dr);
                            
                            this.dgvSource.Rows.Remove(dgr);
                        }这是我的代码，（我要做的功能是从第一个grid选择一行或多行点击一个按钮把选择的多行移动到第二个grid中。）移动到第二个后我想把第一个grid选择的行给删除了，问题就出在这里。不知道怎么删除，this.dgvSource.Rows.Remove(dgr);
dgvSource 是个gridControl 他没有.Rows.Remove

Answer 8

通过gridView1.GetSelectedRows()方法可以得到选中行的行号数组，之后循环该数组进行复制或删除，非常简单啊。

Answer 9

但是我的那个按钮是在grid外面

Answer 10

或者换个思路，你点击按钮进行了两个操作：把选择的数据从A表删除，插入到B表。如果这样的话，重新查询A表不就可以了么？
