我的网页中有一个RadGrid,其中有4个字段:
1)公司清单(下拉清单)
2)金额(文本框)
3)备注(文本框)
公司下拉列表中的数据如下:
TX-需要0%的税
GRE-需要11%的税
EP-要求0%税
BL-需要6%税
TL-要求0%税
要求1:
在更改“下拉列表”值时,同时“添加新记录”
在“编辑”记录中,“金额”和“备注”文本框为空。
为此,我尝试放置“ DropDown_SelectedIndexChanged”事件代码
但是由于我的RadGrid在asp:FormView内,所以当
我从RadGrid重新选择项目,代码不起作用
要求2:
如果下拉列表中所选项目的百分比为0%(文本),则“金额”文本框应
在文本框中使用0.00值禁用。
为此,我尝试了以下代码:
protected void rggst_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{
GridEditableItem item = e.Item as GridEditableItem;
DropDownList list = item.FindControl("ddlCompany") as DropDownList;
list.DataTextField = "TaxDescription";
list.DataValueField = "TaxId";
list.DataSource = IPRRequest.DLTaxCode(CorporateGroupId);
list.DataBind();
if (list.Items.FindByValue("0%"))
{
if (e.Item is GridEditFormInsertItem)
{
GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;
TextBox txt = (TextBox)insertItem["Amount"].Controls[0];
txt.Text = "0.00";
txt.Enabled = false;
}
}
}
}
但是每次我出现以下错误时:
无法将类型'System.Web.UI.WebControls.ListItem'隐式转换为'bool'
以下是用于RadGrid的HTML和C#代码Im:

这是我为要求1尝试的代码:
protected void ddlTaxCodes1_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList taxCodesList = (DropDownList)sender;
GridEditableItem item = (GridEditableItem)taxCodesList.NamingContainer;
string grossAmountTxt = (item["LIGrossAmt"].Controls[0] as TextBox).Text;
string TaxAmt = (item["LITaxAmt"].Controls[0] as TextBox).Text;
string TaxableAmt = (item["LITaxableAmt"].Controls[0] as TextBox).Text;
string Description = (item["LIDescription"].Controls[0] as TextBox).Text;
grossAmountTxt = "";
TaxAmt = "";
TaxableAmt = "";
Description = "";
}
请让我知道我在代码中犯了什么错误。请注意,我是Telerik的新手。提前致谢。
最佳答案
以下是我为需求创建的示例代码,并且可以很好地满足上述两个需求。
另外,asp:FormView不会影响SelectdIndexChanged事件代码,并且一切正常。
protected void ddlTaxCodes1_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlAcCode.SelectedValue != null || ddlAcCode.SelectedValue != "")
{
ddlAcCode.Enabled = false;
string selItem = ddlAcCode.SelectedItem.Text;
if (selItem.Contains("0%"))
{
txtAmount.Text = "0.00";
txtAmount.Enabled = false;
txtRemark.Text = "";
}
else
{
txtAmount.Text = "";
txtRemark.Text = "";
}
}
}
关于c# - RadGrid,dropDown SelectedIndexChanged事件在ASP FormView中不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/31645834/
