需求: 某表单如果有附件,则显示图片;如果没有,则不显示。
解决方案:
1.建一个Datagrid名为Result,form_no栏位是键接栏,最后一列是附件,用模版列。
<asp:datagrid id="Result" style="Z-INDEX: 101; LEFT: 8px; POSITION: absolute; TOP: 280px" runat="server"
Width="728px" Height="149px" Visible="False" AutoGenerateColumns="False" Font-Size="Smaller">
<Columns>
<asp:HyperLinkColumn DataNavigateUrlField="form_no" DataNavigateUrlFormatString="SelectResult.asp?form_no={0}"
DataTextField="form_no" HeaderText="表单号"></asp:HyperLinkColumn>
<asp:BoundColumn DataField="form_status" HeaderText="状态"></asp:BoundColumn>
<asp:BoundColumn DataField="doc_no" HeaderText="异常通知单号"></asp:BoundColumn>
<asp:BoundColumn DataField="date_app" HeaderText="开立日期"></asp:BoundColumn>
<asp:BoundColumn DataField="PS_FZ" HeaderText="责任人员"></asp:BoundColumn>
<asp:BoundColumn DataField="PS_JA" HeaderText="结案负责人员"></asp:BoundColumn>
<asp:BoundColumn DataField="MS_XX" HeaderText="异常现象描述"></asp:BoundColumn>
<asp:TemplateColumn HeaderText="附件">
<HeaderTemplate>
<FONT face="宋体">附件</FONT>
</HeaderTemplate>
<ItemTemplate>
<FONT face="宋体">
<asp:Image id="Image1" runat="server" Visible="False" ImageUrl="../img/wenjian1.GIF"></asp:Image></FONT>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:datagrid>
Width="728px" Height="149px" Visible="False" AutoGenerateColumns="False" Font-Size="Smaller">
<Columns>
<asp:HyperLinkColumn DataNavigateUrlField="form_no" DataNavigateUrlFormatString="SelectResult.asp?form_no={0}"
DataTextField="form_no" HeaderText="表单号"></asp:HyperLinkColumn>
<asp:BoundColumn DataField="form_status" HeaderText="状态"></asp:BoundColumn>
<asp:BoundColumn DataField="doc_no" HeaderText="异常通知单号"></asp:BoundColumn>
<asp:BoundColumn DataField="date_app" HeaderText="开立日期"></asp:BoundColumn>
<asp:BoundColumn DataField="PS_FZ" HeaderText="责任人员"></asp:BoundColumn>
<asp:BoundColumn DataField="PS_JA" HeaderText="结案负责人员"></asp:BoundColumn>
<asp:BoundColumn DataField="MS_XX" HeaderText="异常现象描述"></asp:BoundColumn>
<asp:TemplateColumn HeaderText="附件">
<HeaderTemplate>
<FONT face="宋体">附件</FONT>
</HeaderTemplate>
<ItemTemplate>
<FONT face="宋体">
<asp:Image id="Image1" runat="server" Visible="False" ImageUrl="../img/wenjian1.GIF"></asp:Image></FONT>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:datagrid>
2.后台处理代码:
//显示附件
string form_no=Request.QueryString["Form_No"];
DataSet dsFile=MyConn.GetFile("BQS.FORM.T601");
if(dsFile.Tables["File"].Rows.Count!=0)
{
ArrayList alFormNo=new ArrayList();
for(int j=0;j<dsFile.Tables["File"].Rows.Count;j++)
alFormNo.Add(dsFile.Tables["File"].Rows[j]["FORM_NO"].ToString());
for(int i=0;i<Result.Items.Count;i++)
{
string strFormNo=((HyperLink)Result.Items[i].Cells[0].Controls[0]).Text.ToString();
if(alFormNo.IndexOf(strFormNo)!=-1)
((System.Web.UI.WebControls.Image)Result.Items[i].FindControl("Image1")).Visible=true;
}
}
string form_no=Request.QueryString["Form_No"];
DataSet dsFile=MyConn.GetFile("BQS.FORM.T601");
if(dsFile.Tables["File"].Rows.Count!=0)
{
ArrayList alFormNo=new ArrayList();
for(int j=0;j<dsFile.Tables["File"].Rows.Count;j++)
alFormNo.Add(dsFile.Tables["File"].Rows[j]["FORM_NO"].ToString());
for(int i=0;i<Result.Items.Count;i++)
{
string strFormNo=((HyperLink)Result.Items[i].Cells[0].Controls[0]).Text.ToString();
if(alFormNo.IndexOf(strFormNo)!=-1)
((System.Web.UI.WebControls.Image)Result.Items[i].FindControl("Image1")).Visible=true;
}
}
