检索ItemDataBound中的RadGrid单元格值-“输入字符串的格式不正确." [英] Retrieve RadGrid cell value in ItemDataBound - "Input string was not in a correct format."

问题描述

我试图基于对radGrid中两个单元格值的比较来设置CssClass.两个单元格的格式都设置为货币{0:c}，因此当我比较它们时，文本字符串中有一个$符号.我知道如何解析字符串以删除$符号，这就是我在做什么.但是，有没有一种方法可以在格式化之前获取单元格的原始文本，这样我就不会出现此错误?

I am trying to set a CssClass based on a the comparison of two cell values in my radGrid. Both cells are formatted for currency {0:c}, so that when I compare them, I have a $ sign in the text string. I know how to parse a string to remove the $ sign, which is what I am doing. However, is there a way to get the raw text of the cell prior to formatting, so that I will not have this error?

这是我的代码:

ASPX:

                        <telerik:RadGrid ID="rgCISPartsInfo" DataSourceID="dsCISItem" AutoGenerateColumns="False"
                        GridLines="None" AllowPaging="False" OnItemDataBound="rgCISPartsInfo_ItemDataBound" runat="server" Width="676px">
                        <MasterTableView AllowPaging="False" DataKeyNames="SalesOrderItemId">
                            <Columns>
                                <telerik:GridBoundColumn HeaderText="COST" DataField="AverageCostPrice" AllowSorting="false"
                                    DataFormatString="{0:c}" HeaderStyle-HorizontalAlign="right" ItemStyle-HorizontalAlign="right"
                                    HeaderStyle-Width="80px">
                                </telerik:GridBoundColumn>
                                <telerik:GridBoundColumn DataField="ExtendedCost" HeaderText="X COST" DataFormatString="{0:c}" HeaderStyle-HorizontalAlign="right" 
                                HeaderStyle-Width="80px" ItemStyle-HorizontalAlign="right"></telerik:GridBoundColumn>
                                <telerik:GridBoundColumn DataField="Weight" HeaderText="WT" HeaderStyle-HorizontalAlign="right" HeaderStyle-Width="80px" 
                                ItemStyle-HorizontalAlign="right"></telerik:GridBoundColumn>
                            </Columns>
                        </MasterTableView>
                    </telerik:RadGrid>

C#:

protected void rgCISPartsInfo_ItemDataBound(object sender, GridItemEventArgs e)
{
    try
    {
        // only access item if not header or footer cell
        if ((e.Item.ItemType == GridItemType.Item) || (e.Item.ItemType == GridItemType.AlternatingItem))
        {
            GridDataItem dataItem = e.Item as GridDataItem;
            GridColumn column = rgCISPartsInfo.MasterTableView.GetColumn("AverageCostPrice");

            decimal cost = Convert.ToDecimal(dataItem["AverageCostPrice"].Text);
            decimal price = Convert.ToDecimal(dataItem["Price"].Text);
            if (cost > price)
            {
                dataItem.CssClass = "Grid_Red_Row";
                throw new Exception("Item Cost is greater than price.");
            }
        }
    }
    catch (Exception ex)
    {
        GlobalHelper.ShowErrorMessage(this.Page.Master, ex.Message);
    }
}

更新: 选定的解决方案是我问题的答案，但是我最终决定简单地将字符串解析为$符号，因为这是最简单的解决方案.

UPDATE: The selected solution is the answer to my question, but I ultimately decided to simply parse the string for the $ sign, as it was the simplest solution.

推荐答案

我将添加带有visible="fasle"和其他唯一名称的RadGridDataBound文件，然后从后面的代码中访问它.

I would add RadGridDataBound filed with visible="fasle" and different unique name and access it from the code behind.

 <telerik:RadGrid ID="rgCISPartsInfo" DataSourceID="dsCISItem" AutoGenerateColumns="False"
                        GridLines="None" AllowPaging="False" OnItemDataBound="rgCISPartsInfo_ItemDataBound" runat="server" Width="676px">
                        <MasterTableView AllowPaging="False" DataKeyNames="SalesOrderItemId">
                            <Columns>
                                <telerik:GridBoundColumn HeaderText="COST" DataField="AverageCostPrice" AllowSorting="false"
                                    DataFormatString="{0:c}" HeaderStyle-HorizontalAlign="right" ItemStyle-HorizontalAlign="right"
                                    HeaderStyle-Width="80px">
                                </telerik:GridBoundColumn>
                                       <telerik:GridBoundColumn HeaderText="COST" DataField="AverageCostPrice" Visiable="false" uniqueName="AverageCostPrice1"  DataField="AverageCostPrice" >
                                </telerik:GridBoundColumn>
                                <telerik:GridBoundColumn DataField="ExtendedCost" HeaderText="X COST" DataFormatString="{0:c}" HeaderStyle-HorizontalAlign="right" 
                                HeaderStyle-Width="80px" ItemStyle-HorizontalAlign="right"></telerik:GridBoundColumn>
                                <telerik:GridBoundColumn DataField="Weight" HeaderText="WT" HeaderStyle-HorizontalAlign="right" HeaderStyle-Width="80px" 
                                ItemStyle-HorizontalAlign="right"></telerik:GridBoundColumn>
                            </Columns>
                        </MasterTableView>
                    </telerik:RadGrid>

C#

  decimal cost = Convert.ToDecimal(dataItem["AverageCostPrice1"].Text);

PS: 我刚刚想到的另一个想法是在ItemDataBound事件期间分配DataFormatString.这样，您将获得原始字符串.

PS: Another idea I just had is to assign the DataFormatString durring the ItemDataBound event. this way you'll have the raw string.
