回发错误
本文关键字：错误 | 更新日期: 2023-09-27 18:18:30
我有一个网页上有一个网格。当您单击编辑时，将打开一个弹出式模式窗口。在弹出式模态窗口中，有一个网格，网格下面有一个下拉列表和保存按钮。当您单击保存时，所选值将插入到位于模态窗口中的网格中。
一切工作正常的第一次，但是，如果你已经关闭了模态窗口，你碰巧做了整个过程一遍(点击编辑在第一个网格>模态窗口显示>选择一个项目在ddl>点击保存按钮)回发错误发生。我使用了一个更新面板，我还在模态窗口内的添加按钮中添加了一个postbacktrigger。
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
第一个网格的编辑按钮中的代码(这将调用要打开的模态窗口)
protected void grd_depreciation_RowEditing(object sender, GridViewEditEventArgs e)
{
Guid DepID = new Guid(grd_depreciation.DataKeys[e.NewEditIndex].Values[0].ToString());
//Show the Depreciation Modal Popup
EditModalDepPopup.Show();
//btnModalDepreciation_Click(sender,e);
//checks the type of depreciation.. Network or Equipment
DropDownList ddldescriptiondep = (DropDownList)(grd_depreciation.Rows[e.NewEditIndex].Cells[0].FindControl("ddlDescriptionDep"));
var incotype = (ddldescriptiondep.SelectedItem).ToString();
populategrd_Editdepreciation(DepID, incotype);
}
下面是模态窗口内add按钮的代码(导致错误的那个):
MarginAnalysi checkmarginanalysisid = MarginAnalysisAssumption_worker.get(a => a.ProjectCode == lbl_projectCode.Text).SingleOrDefault();
DepreciationMatrix tblDepreciationMatrix = new DepreciationMatrix();
tblDepreciationMatrix.DepMatrixID = Guid.NewGuid();
tblDepreciationMatrix.DepID = new Guid(ViewState["DepID"].ToString());
tblDepreciationMatrix.IncCapexOpexID = new Guid(ddDepreciationModalEmpty.SelectedValue);
DepreciationMatrix_worker.insert(tblDepreciationMatrix);
DepreciationMatrix_worker.submit();
EditModalDepPopup.Show();
populategrd_Editdepreciation(new Guid(ViewState["DepID"].ToString()), ViewState["incotype"].ToString());
在模态窗口上填充网格的代码:
//Populate Edit Depreciaiton Grid on Modal
public void populategrd_Editdepreciation(Guid DepID, string incotype)
{
ViewState["DepID"] = DepID;
ViewState["incotype"] = incotype;
var x = from a in DepreciationMatrix_worker.get(a => a.DepID == DepID)
select new { a.DepMatrixID, a.IncCapexOpexID };
grd_Editdepreciation.DataSource = x;
grd_Editdepreciation.DataBind();
//Populate dropdownlist on edit depreciation modal
MarginAnalysi checkmarginanalysisid = MarginAnalysisAssumption_worker.get(a => a.ProjectCode == lbl_projectCode.Text).SingleOrDefault();
//Selects eithers Equipment or Network Depreciation
string test = incotype.ToUpper();
if (test.Contains("EQUIPMENT"))
{
var dropdowndepreciationmodal = from a in tblIncCapexOpex_worker.get(a => a.MarginAnalysisID == checkmarginanalysisid.MarginAnalysisID && a.IncCoTypeID == "CAPEX" && a.DepreciationTypeID == "EQUIPMENT")
select new { text = a.Description, value = a.IncCapexOpexID };
populateDropdownlist(ddDepreciationModalEmpty, dropdowndepreciationmodal, true);
}
else
{
var dropdowndepreciationmodal = from a in tblIncCapexOpex_worker.get(a => a.MarginAnalysisID == checkmarginanalysisid.MarginAnalysisID && a.IncCoTypeID == "CAPEX" && a.DepreciationTypeID == "NETWORK")
select new { text = a.Description, value = a.IncCapexOpexID };
populateDropdownlist(ddDepreciationModalEmpty, dropdowndepreciationmodal, true);
}
}
模式弹出的Aspx代码。这段代码位于updatepanel标签内。

看看我对这个问题的回答，你就知道哪里不对了。
https://stackoverflow.com/a/8572928/168371问题不在于你的代码，而是一些不在更新面板内的控件，并且在标记中有旧值。
