i want to pass the values from one page to another

There are numerous ways to do this and it all boils down to the requirement as each has its own pros and cons

You can use

Session, query strings, cookies, form post data

just use the code like this,

Response.Redirect("yourpage.aspx?id=SelectedCellValue")

'in the second page you can get the qury string value like this

Dim strValue As String

strValue = Request.QueryString("SelectedCellValue").ToString()

"Object reference not set to an instance of an object. "

Please tell me which event i hav to write and any conditions.

Well.. When you Redirect to any page using Server side script like Resonse.Redirect("somepage.aspx?id=" + someid.ToString()) that means its a Get action which means, one can query id using Request.QueryString() method. Before you get any querystring, check for any querystring avaialbe from the redirected url using Reqeust.QueryString.HasKeys() and then get key/value from it, otherwise your query will fail.

Another case is, When you submit a Page by clicking Submit button, then the action is Post, in such case on server side, you can query from Request.Form[] collection.

Now, in your case, I would guess you are using Redirect method of Response and obviously you should be able to query using QueryString() collection.

Another thing i noticed is do not apply ToString() when you expect casting from QueryString[], use Convert.ToString() instead. Since Convert.ToString() helper handles nulls!

If you are not still clear, send me your code, so that i can be able to narrow the solution.

hope this helps!

Hi,

I undestood your problem. what you would need is, implement the logic as shown below:

FirstPage.aspx

<body>
    <form id="form1" runat="server">
    <div>
    Category:   <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <br />
        <asp:Button ID="Button1" runat="server" Text="Submit" onclick="Button1_Click" />
    </div>
    <asp:Label ID="Label1" runat="server"></asp:Label>
    </form>
</body>

FistPage.aspx.cs

protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.QueryString.HasKeys())
        {
            string category = Convert.ToString(Request.QueryString["Category"]);

this.Label1.Text = "You have posted " + category + "from Second Page";

        }
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("~/SecondPage.aspx?Category=" + TextBox1.Text);
    }

SecondPage.aspx

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
        <br />
        Send this to First Page again:
        <asp:Button ID="Button1" runat="server" Text="Send to First Page"
            onclick="Button1_Click" />
    </div>
    </form>
</body>

SecondPage.aspx.cs

protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.QueryString.HasKeys())
     {
            string category = Convert.ToString(Request.QueryString["Category"]);
            this.Label1.Text = category;
     }

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("~/FirstPage.aspx?Category=" + Label1.Text);
    }

with this logic, your scenario should work... or buzz me if you are not clear

krishna

_{Friday, April 11, 2008 5:06 AM}

basically i'd say dont store images to database, just store the filenames in an 1:n table.

well you'll just add a simple " select .. from thing t join thing_image i on i.id=t.imageid where t.id = " + QueryString["id"] in your sql string? (better using parameters)

please tell me if i misunderstood

_{Sunday, April 13, 2008 11:44 AM}

thank you sir.

but i didn't understand what u mean.if u explain clearly it will be more useful for me.

thank you sir.

_{Sunday, April 13, 2008 1:58 PM}

create table realty {

id int primary key,

......

.....
}

create table realtyimage {

realtyid int foreign key references realty,
filename varchar(255),

}

store the filenames into realtyimage with realtyid of the realty the image belongs to.

sorry if that didnt help maybe you could explain more about your problem

Hi All,

I would like to know how to pass value in a textbox of one webform to a datagrid in another form. Can anyone help me with it...

Thanks

WOW that will really help him.. i reported him.

first go to the textchanged event of the textbox.

then make a decision: sessions or querystring.

i use sessions. so in the textchanged event type:

Session["parameter"] = txtYourTextBox.Text; response.redirect("othersite.aspx");

in the othersite.aspx (page load event):

 if(!IsPostBack) {
   // set the value to the gridview here, like:
   string strParameter = Session["parameter"] as string;
}

with querystrings you drop the Session["parameter"] = ... and use response.redirect("othersite.aspx?parameter=" + txtYourTextBox.Text); instead

in the othersite.aspx, page load event:

if(!IsPostBack) {
   string strParameter = Request.QueryString["parameter"];
}

i hope that helps

_{Friday, August 22, 2008 7:30 AM}

thanks for the reply..

thanks,

bluee

_{Friday, August 22, 2008 7:44 AM}

sorry but isnt datagrid an .net form application control, i only know about a gridview, datalist and repeater in asp.net 2.0?

do you mean a gridview? do you use asp.net 2.0?

if its a gridview, it would be

GridView1.Rows[0].Cells[0].Text = Session["Parameter"];

_{Friday, August 22, 2008 8:11 AM}

thank you..

sorry i was wrong... i actually meant a gridview.. thanks anyways
