Devexpress MVC Gridview

1. 根据选中的KeyValue 来获取其他field的value

// Gridview settings
  settings.CustomJSProperties = (s, e) =>
            {
                Dictionary<object, int> visibleIndices = new Dictionary<object, int>();
                for (int i = 0; i < ((MVCxGridView)s).VisibleRowCount; i++)
                    visibleIndices.Add(((MVCxGridView)s).GetRowValues(i, ((MVCxGridView)s).KeyFieldName), i);
                e.Properties["cpIndices"] = visibleIndices;
            };

//javascript调用

GridView.cpIndices[Key,"fieldName")

2. 根据某些field的value来改变cell的backcolor

//Gridview settings

 settings.HtmlDataCellPrepared = (sender, e) =>
            {
                var gv = sender as MVCxGridView;
                string ls_Status = gv.GetRowValues(e.VisibleIndex, "Status") == null ? "" : gv.GetRowValues(e.VisibleIndex, "Status").ToString();
                string[] la_EditorField = new string[] { "TaxInvCust", "IseVAT", "TaxInvRemark" };
                if (ls_Status != "1" && la_EditorField.Contains(e.DataColumn.FieldName))
                {
                    e.Cell.BackColor = System.Drawing.Color.Transparent;
                }
            };

3.通过jquery获取gridview cell的value.

//Gridview settings, id format =  gridviewname_fieldname_visableIndex

   settings.HtmlDataCellPrepared = (sender, e) =>
            {
                e.Cell.Attributes.Add("id", string.Format("{0}_{1}_{2}", settings.Name, e.DataColumn.FieldName, e.VisibleIndex));
            };

//JavaScript function

function GetCellText(as_GridViewName,as_fieldName,ai_Index)
    {
        var ls_Amt = "";
        var ls_text = $("#" + as_GridViewName + "_" + as_fieldName + "_" + ai_Index).text();
        ls_Amt = parseFloat(ls_text.substring(0, ls_text.indexOf(".") + 3).replace(/\,/g,"")).toFixed(2);
        return ls_Amt;
    }

4.设置hyperlink column

//Gridview settings
  settings.Columns.Add(column =>
            {
                column.FieldName = "TaxInvNo";
                column.Caption ="Tax Inv. No.";
                column.Width = 90;
                column.EditFormSettings.Visible = DevExpress.Utils.DefaultBoolean.True;
                column.SetDataItemTemplateContent(container =>
                {
                    if (container.VisibleIndex < 0)
                        return;

                    var ls_Url = DataBinder.Eval(container.DataItem, "Url").ToString();
                    if (ls_Url != null && ls_Url != "")
                    {
                        helper.DevExpress().HyperLink(hyperlink =>
                        {
                            var li_VisibleIndex = container.VisibleIndex;
                            var ls_KeyValue = container.KeyValue;
                            hyperlink.Name = "h1" + ls_KeyValue;
                            hyperlink.Properties.Text = DataBinder.Eval(container.DataItem, "TaxInvNo").ToString();
                            hyperlink.Properties.TextField = "TaxInvNo";
                            hyperlink.NavigateUrl = ls_Url.ToString();
                            hyperlink.Properties.Target = "_blank";
                        }).Render();
                    }
                    else
                    {
                        if (DataBinder.Eval(container.DataItem, "TaxInvNo") != null)
                            helper.ViewContext.Writer.Write(DataBinder.Eval(container.DataItem, "TaxInvNo").ToString());
                    }
                });
            });//Tax Inv. No
