Hello Friends,

I am encrypting an string and passing it with URL,

But when it is decrypted it is creating the following error :

System.FormatException: Invalid length for a Base-64 char array. at System.Convert.FromBase64String(String s)

but its working fine on local.

I have noticed one thing that which encrypted string is having '+' in it only that encrypted string creating this error while decrypting online.

And same encryped string is decrypted on local it is working fine...

I am not able to understand why it is happening.

In .Net, the method you're looking for is this one: System.Web.HttpUtility.UrlEncode().

http://msdn2.microsoft.com/en-us/library/system.web.httputility.urlencode.aspx

Hope this helps,

Server send messages to client?In C/S system there maybe some solutions use socket.
But in web applications there is no way to achieve this.
For a substitute,you can use ajax to post some request periodly for check is there are new messages.If ajax request find new message,then get it and show it in a pop up window. Sniff | :^)

yes thats what i want, but i cannot inject a javasript to the page to opo up a window if there is a message, i get an exception [which is shown in an alert window ] and i searched for the solution and what i got is to avoid this response.write part from ajax related part. any way to pop up a window? it can be easly done if there is no ajax code.

Use window.setInterval to watch if there is a new message.I mean the ajax is you use a Msxml2.XmlHTTP ActiveX object to post some request and get response from it.All of these operations are in javascript.;P;P;P Don't use Ajax.dll or other dll please Big Grin | :-D

Get RowIndex from GridView when Click a Button

19-Apr-07 18:38

I have a GridView that contains a few Template Columns. In one of my Template Columns I have a Button and a TextBox. When the user Clicks the button, I want to place a value into the TextBox next to it. In order to do that, I figured I could get the RowIndex of the GridView row containing the clicked Button. Then I could find the particular TextBox Control in that row and fill that TextBox with the value I wish.

How can I get the RowIndex from a GridView when a user Clicks a Button within in….on the Server Side.

Any help would be appreciated! Thanks

Hi,

You can achieve this as following.

Create an event handler for a buttonclick event in the code behind.

protected void Bttn_Click(object sender, EventArgs e)
{
Button bttn = (Button)sender;
GridViewRow gr = (GridViewRow)(bttn.Parent.Parent);
Response.Write(gr.RowIndex);
}

and assign its name to the onClick event of teh button inside the TemplatedColumn in the gridview.

<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="buttn" runat="server" Text="Click" OnClick="Bttn_Click"/>
</ItemTemplate>
</asp:TemplateField>

This way you can get the RowIndex of the GridRow Containting the button and then you can find the textbox from that row using FindControl Method.

I hope this will help you.

Thanks and Regards,

Hi,

I have a web config file

configuration>
<system.web>
<customerrors mode="Off">
<authentication mode="Forms">
<forms name="AuthCookie" path="/"
="" loginurl="login.aspx" protection="All" timeout="30">
<credentials passwordformat="Clear">
<user name="jeff" password="test">
<user name="mike" password="test">

<authorization>
<deny users="?">

<compilation debug="true">

But in web config file you are using some data for user name and password but what I need pass a database in which I stored usernames and passwords. I have no idea how can I check weather users and passwords matches with columns UserName and Password in my table. Table name is tbUsers.

I have connection String

Solution is for .net 2.0

Add these lines to the web.config

<authentication mode="Forms">
<forms name="AuthCookie" path="/" loginUrl="login.aspx" protection="All" timeout="30" defaultUrl="test2.aspx">
</forms>
</authentication>
<authorization>
<deny users="?"/>
</authorization>

the authorization is used to prevent the anonymous user. in this example my default url is text2.aspx page

In login page write the following code in the button click event
if (ValidateUser())
{
FormsAuthentication.RedirectFromLoginPage(txtuserName.Text, false);
}

ValidateUser() is user-defined function where you will write the code to check whether the password given my user matches with the password available in the database.

In other page's nothing is needing to write for validation
