Hi Aliyilmaz,
Hello everyone, my problem is that I'm exporting the gridview to another gridview with the selected checkbox data. But if I use an update panel this does not work. How can I solve this problem.According to your code, I have written a test demo on my computer.
I guess you put the gvSiparis girdview out of the updatepanel.
As far as I know, updatepanel will partly refresh the page.
If you put gvSiparis gridview out of the updatepanel, it will not be reloaded.
I suggest you could put the gvSiparis gridview inside the updatepanel, it will work well.
More details, you could refer to follow codes:
Aspx:
<div> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:UpdatePanel runat="server" UpdateMode="Conditional" > <ContentTemplate> <asp:GridView ID="example" CssClass="table table-striped table-bordered table-hover" AutoGenerateColumns="false" DataKeyNames="ID" runat="server" ClientIDMode="Static"> <Columns> <asp:TemplateField HeaderText="Ürün Seç" ItemStyle-Width="10%"> <ItemTemplate> <asp:CheckBox ID="chcsec" CssClass="form-control" runat="server" AutoPostBack="true" OnCheckedChanged="chcsec_CheckedChanged" /> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Ürün Ad" ItemStyle-Width="20%"> <ItemTemplate> <asp:Label ID="lblUrun" runat="server" Text='<%# Eval("UrunAd") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txturunad" runat="server" Text='<%# Eval("UrunAd") %>'></asp:TextBox> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Stok" ItemStyle-Width="10%"> <ItemTemplate> <asp:Label ID="lblStok" Style="padding: 3px 5px;" runat="server" Text='<%# Eval("Stok") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtstok" Style="padding: 3px 5px;" runat="server" Text='<%# Eval("Stok") %>'></asp:TextBox> </EditItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> <asp:GridView ID="gvSiparis" runat="server"></asp:GridView> </ContentTemplate> </asp:UpdatePanel> </div>Code-behind:
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { DataTable d1 = new DataTable(); d1.Columns.Add("ID"); d1.Columns.Add("UrunAd"); d1.Columns.Add("Stok"); d1.Rows.Add("1", "aaa", "1"); d1.Rows.Add("2", "bbb", "2"); d1.Rows.Add("3", "ccc", "3"); example.DataSource = d1; example.DataBind(); } } protected void chcsec_CheckedChanged(object sender, EventArgs e) { if ((sender as CheckBox).Checked) { if (ViewState["CheckedRow"] == null) { DataTable dt = CheckedData(); ViewState["CheckedRow"] = dt; } else { DataTable previousCheckedRows = ViewState["CheckedRow"] as DataTable; DataTable dtCurrentCheckedRows = CheckedData(); dtCurrentCheckedRows.Merge(previousCheckedRows); ViewState["CheckedRow"] = dtCurrentCheckedRows; } } else { GridViewRow row = ((sender as CheckBox).NamingContainer as GridViewRow); Label lblUrun = (row.FindControl("lblUrun") as Label); Label lblStok = (row.FindControl("lblStok") as Label); DataTable deleteRow = (ViewState["CheckedRow"] as DataTable).DefaultView.ToTable(true); DataRow[] dr = deleteRow.Select("UrunAd = '" + lblUrun.Text + "' AND Stok = '" + lblStok.Text + "'"); foreach (DataRow d in dr) { deleteRow.Rows.Remove(d); } ViewState["CheckedRow"] = deleteRow; } gvSiparis.DataSource = (ViewState["CheckedRow"] as DataTable).DefaultView.ToTable(true); gvSiparis.DataBind(); } private DataTable CheckedData() { DataTable dt = new DataTable(); dt.Columns.AddRange(new DataColumn[] { new DataColumn("UrunAd"), new DataColumn("Stok", typeof(int)) }); foreach (GridViewRow rw in example.Rows) { if (rw.RowType == DataControlRowType.DataRow) { CheckBox chk = (CheckBox)rw.Cells[0].FindControl("chcsec"); if (chk.Checked) { //HiddenField hdID = (HiddenField)rw.Cells[0].FindControl("hdID"); Label lb = (Label)rw.Cells[1].FindControl("lblUrun"); Label lb1 = (Label)rw.Cells[2].FindControl("lblStok"); int stok = Convert.ToInt32(lb1.Text); dt.Rows.Add(lb.Text, lb1.Text); chk.Checked = false; } } } return dt; }Result:
