这是我的aspx:
<td>
<asp:FileUpload ID="fileupload" runat="server" />
</td>
CS:
这是为了插入:
SqlCommand com = new SqlCommand("StoredProcedure1", con);
com.CommandType = CommandType.StoredProcedure;
com.Parameters.AddWithValue("@Name", Textusername.Text.Trim());
com.Parameters.AddWithValue("@Class", Textclass.Text.Trim());
com.Parameters.AddWithValue("@Section", Textsection.Text.Trim());
com.Parameters.AddWithValue("@Address", Textaddress.Text.Trim());
try
{
string filename = Path.GetFileName(fileupload.PostedFile.FileName);
fileupload.SaveAs(Server.MapPath("~/Images/" + filename));
com.Parameters.AddWithValue("@Image", "Images/" + filename);
com.ExecuteNonQuery();
Response.Redirect("studententry.aspx");
}
catch (Exception ex)
{
btnsub.Text = ex.Message;
}
插入所有详细信息后,它显示为this:
这是从gridview编辑的:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
SqlConnection con = Connection.DBconnection();
if (e.CommandName == "EditRow")
{
GridViewRow gr = (GridViewRow)((Button)e.CommandSource).NamingContainer;
int index = gr.RowIndex;
hiddenfield.Value = index.ToString();
Textid.Text = gr.Cells[0].Text;
Textusername.Text = gr.Cells[1].Text;
Textclass.Text = gr.Cells[2].Text;
Textsection.Text = gr.Cells[3].Text;
Textaddress.Text = gr.Cells[4].Text;
}
}
当我从GridView
编辑特定行时,它会编辑预期图像。
因此图像不可编辑。我可以知道如何编辑图像吗?
答案 0 :(得分:0)
试试这个,
首先在Gridview控件内的图像控件旁边添加2个隐藏(hd_gv,hd_update)字段,然后在窗体中添加其他字段,并使用图像src设置隐藏字段值。
现在在Gridview_RowCommand 获取 src和设置 hd_update隐藏字段值,所以你的代码看起来像这样
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
SqlConnection con = Connection.DBconnection();
if (e.CommandName == "EditRow")
{
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
HiddenField imgSRC = (HiddenField)row.FindControl("hd_gv");
hd_update.Value=imgSRC.Value;
}
现在在你的更新函数上首先检查Fileupload控件是否有任何文件,如果是,然后上传文件并用新上传文件更新图像src,否则设置hd_update(隐藏字段)值。
按钮单击
时更新代码如下所示string Filename = hd_update.Value; // "HIDDEN_FIELD_IMAGE_SRC";
if (fileupload.HasFile)
{
//code to upload and set Filename variable with new file
Filename="NEW FILE NAME";
}
