how to force a page to post back from another page? r_jaz29-Mar-07 10:21 r_jaz 29-Mar-07 10:21  Hi every one, I need help in making a page to post back when another page postsback, lets say when a button is clicked in the other page!! Your help is highly appreciated.. Thanks Re: how to force a page to post back from another page? liliblacsharp29-Mar-07 19:19 liliblacsharp 29-Mar-07 19:19  You mean, you have 2 web pages? 1 is parent and another is the child? Example: parentWeb.aspx -> main web page. parentWeb.aspx call another webPage (ex. childWeb.aspx). When user click button on childWeb.aspx, you can make parentWeb.aspx post back by this way: On childWeb.aspx: var wndParams = window.dialogArguments; opener = wndParams[0]; --> parentWeb.aspx function onButtonClick() { opener.doWebPostback(); } On parentWeb.aspx: function doWebPostback() { document.Form1.submit(); } Hope this can help you Lili Re: how to force a page to post back from another page? r_jaz29-Mar-07 20:28 r_jaz 29-Mar-07 20:28  First of all thank you.. I have a page contains 2 frames, each is a .aspx, and I want to force the second one to post back when a button in the first page is clicked, its not a parent and child pages.. Thanks again anyway.. How to prohibit repeated passwords in default membership? moazzamahmed29-Mar-07 8:51 moazzamahmed 29-Mar-07 8:51  hi all I've implemeneted microsofts default membership provider, everything works great. I need to restrict users from changing their password to a password they already used in the last x months. Does anyone know how the default membership provider can do this? If not, any ideas on how to implement it? we have passwords hashed, so we cant really store em outside of aspnet ourseleves. thanks in advance. moazzam Re: How to prohibit repeated passwords in default membership?

Re: How to prohibit repeated passwords in default membership? Not Active30-Mar-07 2:23 Not Active 30-Mar-07 2:23  You would of course need to save n number of previous password hashes to compare the new one against. Where to save them is up to you but a simple update trigget on the table could be used. only two letters away from being an asset Writing Validation summary message from Client side script snir_ya29-Mar-07 6:32 snir_ya 29-Mar-07 6:32  Hi, I have a validation summary control (bulleted list disp mode) that i want to update not(!) when the page is submitted but while i'm doing client side javascript validation. Is it possible? And if it is possible, how do you add a bulleted message? Thanks a lot in advance and happy passover! Snir.

I want to use validation summary capability of displaying and managing a bulleted list of messages. Only i want that the range validators will write their error messages during client side validation and not during submit. Re: Writing Validation summary message from Client side script snir_ya29-Mar-07 7:48 snir_ya 29-Mar-07 7:48  Does anybody know if it's even possible? Re: Writing Validation summary message from Client side script Kunal P29-Mar-07 21:44 Kunal P 29-Mar-07 21:44  all ur validation controls have EnableClientScript = true property.. that means as soon as the text changes, the validation will fire.. and wen u`ll click on the submit button, the validation summary will be displayed.. and no page postback will occur... so check.. EnableClientScript property.. Kunal Using for loops within aspx? muppet00729-Mar-07 6:26 muppet007 29-Mar-07 6:26  I'm trying to save myself some time and loads of typing, and want to use a for loop to generate table rows within a DataList element. This is what the code looks like in general: <asp:datalist ...=""> <itemtemplate> ... <table...> ... <% for (int i=1; i<=10; i++) { %> <%# DataBinder.Eval(Container.DataItem, "somefield_a_"+i.ToString())%><%# DataBinder.Eval(Container.DataItem, "somefield_b_"+i.ToString())%><%# DataBinder.Eval(Container.DataItem, "somefield_c_"+i.ToString())%><% } %> The dots are there to make this readable, there are hundreds of fields in the data source and the template is quite large. Some of them end in _1, _2, _3 etc and rather than typing in all the rows I'd like to just specify one and let the for loop do the work for me. I guess something like this would have been fine in ASP but it's obviously not working in .NET. Is there any way to achieve what I'm trying to do in .NET? Re: Using for loops within aspx? kubben29-Mar-07 6:40 kubben 29-Mar-07 6:40  I think you can get it to work, but you may need to use a page.Bind in your code behind. I haven't tried to do a for loop, but I have done if statements. So I would try a page.bind. Ben Re: Using for loops within aspx? muppet00729-Mar-07 6:52 muppet007 29-Mar-07 6:52  If I understand correctly Page.Bind is just like calling DataBind on every control. There's no problem with the data source here, or data binding, it's all working fine.. I'd just like to have a for loop that goes through the row and replaces the last character in the field name with the one from the variable. Rather than doing this: <%# DataBinder.Eval(Container.DataItem, "somefield_a_1")%><%# DataBinder.Eval(Container.DataItem, "somefield_b_1")%><%# DataBinder.Eval(Container.DataItem, "somefield_c_1")%><%# DataBinder.Eval(Container.DataItem, "somefield_a_2")%><%# DataBinder.Eval(Container.DataItem, "somefield_b_2")%><%# DataBinder.Eval(Container.DataItem, "somefield_c_2")%><%# DataBinder.Eval(Container.DataItem, "somefield_a_3")%><%# DataBinder.Eval(Container.DataItem, "somefield_b_3")%><%# DataBinder.Eval(Container.DataItem, "somefield_c_3")%>etc.. you get the picture.. Re: Using for loops within aspx? kubben29-Mar-07 7:20 kubben 29-Mar-07 7:20  Actually, what I have found is without the Page.Bind the <% for loop stuff doesn't get evaluated. I guess I should say that if your code above is in a control then you can just bind the control as well. I recently had a formview that was doing some conditional stuff with. If I didn't do the forview.databind you would see the <% if statements on the page. So what I am saying is that Page.Bind will hopefully work for you in translating your for loop to the code above.

Kunal Re: inserting listbox item into databse Not Active29-Mar-07 5:52 Not Active 29-Mar-07 5:52  First, you should be using stored procedures. If you can't then at least use a SqlCommand and SqlParameters. Second, never allow unvalidated text to be inserted into your command or database. only two letters away from being an asset Re: inserting listbox item into databse Kunal P29-Mar-07 5:55 Kunal P 29-Mar-07 5:55  i know its bad programming practice, and very much prone to sql injection... but just a mini project thing.. for some hit and trial..
