asp.net - Getting TextBox's Text on Next Page if Visible is false (Cross-Page Postback) -


i have aspx page contains 2 tables (each textbox controls in it).

when page first rendered, first table shown (second table's visible property set false). user fills out textboxes , clicks continue button.

now, first table's visible = false; , second table's visible = true; , user fills out second table.

submit button clicked. postbackurl of button set new page in i'm trying , display entered in last page using request.form["ctrlname"];

the problem is... first table's visibility set false server never rendered it. shouldn't data still in viewstate? how retrieve data first table not rendered?

obviously cant use request.form["table1ctrlname"]; data textbox in table1, isn't there way of querying incoming viewstate directly data?

you can use previouspage property on next page.

example:

page-1 (aspx):

<asp:panel id="pnl1" runat="server">     first text box:     <asp:textbox id="txt1" runat="server"></asp:textbox> </asp:panel> <asp:panel id="pnl2" runat="server" visible="false">     second text box:     <asp:textbox id="txt2" runat="server"></asp:textbox> </asp:panel> <asp:button id="btnnext" runat="server" onclick="btnnext_click" text="next" /> <asp:button id="btnsubmit" runat="server" text="submit" postbackurl="~/page2.aspx" />

page-1 (code):

protected void btnnext_click(object sender, eventargs e) {     this.pnl1.visible = false;     this.pnl2.visible = true; }

page-2 (code):

protected void page_load(object sender, eventargs e) {     if (this.ispostback)     {         var svalue1 = ((textbox)this.previouspage.findcontrol("txt1")).text;         var svalue2 = ((textbox)this.previouspage.findcontrol("txt2")).text;         console.writeline(svalue1);         console.writeline(svalue2);     } }

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
