View 3 RepliesWhat is the best solution for adding Textbox controls dynamically to a page when a button is pressed?
The secnario is: "The page initially loads with 3-4 textboxes already displayed but the user needs another textbox added. They click add textbox and another textbox control appears."
I would hope to be able to do this within a updatepanel and use AJAX async postback.
- I'm using a RequiredFieldValidator to check whether the text box is empty. I only wanted this validation to run when I press one specific button.
- I dont want the validation to be done on every button control within a page. For example, i have 2 buttons, one is showing a list of data and another will be checking for an empty text boxes. So, when I click the show list button, I dont want the validation to be run, what I want is the validation to be run on the check empty text boxes button.
I have an ASP.NET GridView that has four columns. The first three are typical BoundField elements bound to a DataTable. The forth is a TemplateField element that I create a DropDownList in on the OnRowCreated event for the GridView.
What I'm attempting to do is walk down the data source for the GridView when a button is pressed. I really just need to get the values for columns one and four of each row. The first three columns have data as expected but the forth is displaying as empty. Is this because it wasn't a part of the DataTable originally? Is there any way to get the value for each drop down as I've described it, or will I need to rework this so each drop down list is a part of the DataTable?
If I'm on a searchable site (example.com for example) and search some data then get a dropdown list, when I click on one of the items, then try to use the browser's back button to go back, I get the error "the page cannot be displayed". Does this have something to do with cookies or history settings?
I don't have this problem with mozilla, but I prefer to use IE for other reasons.
I have to set enter key event to text box, it work fine in IE, but not in firefox.
Here my code:
function DoClickToButton() {
var keycode = (event.keyCode ? event.keyCode : (event.which ? event.which : event.charCode));
alert(keycode);
if (keycode == 13) {
document.getElementById('<%=Button1.ClientID %>').click(); return false;
}
else {
return true
};
}

View 3 RepliesI have the Problem with the File Upload window. When I used it the first time it works perfect but when I call the same functionality to open and upload a File the open button (in the "Choose File to Upload" Dialog) is pressed to fast. So the Test can not write the complete path of the File over set and so the I can not open the File. The Source Code of the function:
public void OpenFileDialogAndUploadCsvFileWithName(string fileName, IE editPage)
{
var fileUploadDialog = editPage.HtmlDialog(Find.ByTitle(PageTitle));
fileUploadDialog.WaitForComplete();
FileUpload fileUpload = fileUploadDialog.FileUpload(Find.ById(new Regex("_FileUpload")));
fileUpload.Set(fileName);
Image image = fileUploadDialog.Image(Find.BySrc(new Regex("/icons/upload.png")));
Element parentElement = image.Parent;
parentElement.FireEventNoWait("onmouseup");
parentElement.FireEventNoWait("onmousedown");
}
The Upload File Dialog is open from Internet Explorer Modal Dialog Window.

I have a page on which the user can define a query. When done, the user enters a name for the query and presses a button. I'd like to process the button click, make a text label (or Span) visible for a few seconds and then have it fade out.
Since it is a postback, I can turn an ASP:Label control to visible - that's easy. Now how do I get jquery to make the label fade away after a few seconds? In a broader sense, how do you get a postback to trigger a jquery method?
Whatever server Control we take on aspx page while in coding phase, all those controls are converted to html controls through the asp.net engine and sent to the requesting web browser. That's fine.
Now, all the controls that are rendered on the browser are html controls. I am bit confused that how after pressing any button (Or any such control that post back pages) page is posted back to the asp.net engine. How such html controls comes to know where (address) they have to go?
Validation controls are good to use but plz guide is there a way that I can prevent validation controls to be validate on input and force them to validate on button press ?
