View 2 RepliesIn my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes
itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.
I have two asp.net applications webapp1 and webapp2, in each application i have a asp.net form Deafult.aspx
I want to do a form submit from Default.aspx in webapp1 and recieve the value in webapp2.
I tried to do it with simply setting action ="webapp2 location" but it is throwing the bellow error
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
I even added the machinekey element to web.config
but it is still showing the same error.
This is the code for webapp1 form which sends data to webapp2

I have been using a querystring to carry over the value of a DDL to the next page. Now I want to carry over values of two Drop down lists through Querystring on to my next page.Here is my code to carry over one DDL using QueryString:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Response.Redirect(String.Format("Option1_result.aspx?ddl1={0}", DropDownList1.SelectedValue))
End Sub
I have a FormView in InsertItem that contains one DropDownList linked to a Table Datasource to display ItemCodes. In that "lookup" table I also have a Retail and Cost field.When the user selects the item from the drop down, how can I have these to field carry over into my new record that is being inserted. The new record also has a Retail and Cost field that are TextBoxes.Basically I am populating the new fields with the default values from the DropDownList.
View 1 RepliesI'm using HttpModule to capture requests to the web server. Before processing the page I'd like to check the values contained in some keys of the Request.Form collection and according to some logic change if necessary. I'd like to do this when BeginRequest event is fired. The problem is that the Request.Form collection is readonly.
View 4 RepliesI have Master Page and ascx user controls in my application.
how would I use the Cross-Page technique using the @ PreviousPageType directive.
useful links or samples to achieve this.
I am trying to use the Page class that exposes a property named PreviousPage from my User Control.
I have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.
1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice
2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.
i need to create a dynamic form that switches the contents of the page without reloading or refreshing the page.

I have a web form where I define an array of type struct and I redirected it in the <script runat="server">
section of the second web form. But when I use that array below, in the <script type="text/javascript">
section in the html code of the same web form an error occured in the for cycle saying that the array (Array1) is undefined, and also the counter which I also defined in <script runat="server"> section.
I have this code in the <script runat="server">
section of the second web form:
public struct Point1
{
public float lat;
public float long1;
}
protected void Page_Load(object sender, EventArgs e)
{
//Retreive from session
Point1[] Array1 = Session["s1"] as Point1[];
//Run a Foreach loop
int nCnt
= 0;
foreach (Point1 p1
in Array1)
{
float x1
= p1.lat;
float y1
= p1.long1;
nCnt++;
}
}
and in the <script
type="text/javascript">
section I have:
var
for (var i = 0; i <
nCnt; i++)
{
lineString.getCoordinates().pushLatLngAlt(Array1[i][0], Array1[i][1],0);
}
lineString = ge.createLineString('');
lineStringPlacemark.setGeometry(lineString);

View 1 RepliesI was told to use a Repeater control in what I am doing which is a "Data Entry" screen with ASP.NET controls -a standard "address" like form. In cases, the fields on the form will repeated twice, once for the original values, one for the changed values. I have not used this control before but it seems like I have to bind to a database. Instead, I have an Entity object that has been obtained via a Repository. Can I bind to an object like this?

<asp:FormView ID="frm_Person" runat="server" DataKeyNames="Person" DataSourceID="ds_edit_Person" DefaultMode="Insert" ViewStateMode="Enabled">
I am trapping the error on the datasource with
<asp:SqlDataSource ID="ds_edit_Person". oninserted="ds_Edit_Person_Sql_Event" onupdated="ds_Edit_Person_Sql_Event".

SqlException sqlex = (SqlException)e.Exception;
lbl_Error.Text = ErrorHandler.TranslateError(sqlex.Number);

lbl_Error.Text = ErrorHandler.TranslateError(0);

I have a form that contains several textboxes and each one paired with a required validator. Each box reads a value from a dataset, and on submit click, update the database with the new value. For some reason, one of the validator always returns the error message even if I enter a value in the textbox. My code is something like this.
