Can HTML Element Into Form-data That Posts Back To The Server
Apr 24, 2010
I am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value.
The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well.
I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?
I have a View that has a select drop-down list and an edit button within a form. What I want to do is have the user select one of the options from the select element, click on the edit button, and get the value of the selected option in the Controller method.
I created my form with <% Html.BeginForm(): %>
and the Controller "Edit" method should be called.
I looked through several online examples, but each one focused on how to set values and the default selected value of the select element, rather than retrieving it from the code in the Controller method. I tried grabbing it from the Request.Form collection like:
string val = Request.Form["myDropDownList"].ToString(); and also: string val = Request.Form["myDropDownList"];
Obviously I didn't do this correctly, because I get a null reference exception. Does anyone have the solution to this issue?
I want to replace a form element with a div and keep the inner html of the form inside the inserted div element. i tried jquery it gives me unkown html element as selection result,
I have a few updatepanel in my asp.net webform . I'm doing some tests and I'm wondering how can i check what data send back to server in different situations ?
Does a response.Redirect first postback to the page that's calling the redirect before actually redirecting? I don't think so but my debugging is showing me that it is.
I can see it doing so and that causes me a problem. The problem is this:
1) My page has an asp.net button on it 2) When the button is clicked, the page posts back of course. Then the following is called in the event handler method for that button:
Response.Redirect("Checkout?frpp=1"), true);
3) But I notice that when the redirect is called, it first goes back and hits the page load for this page, the page that's doing the redirecting. Well that is causing me problems because it's calling code that I don't want it to be calling again such as this:
if (!IsPostBackl) ShowOrderItems();
so it's like I'm doing a 2nd postback:
first postback happens when you click the button, hits the event handler, runs my handler method which calls the Redirect. Redirect is called but it's doing another postback to the same page here..why?
I've been looking at google for the past few hours, trying to find an issue to a apparently simple problem. I have a UserControl named RolloverLink that basically contains a asp:LinkButton and a <img /> . I tried setting the OnClick handler like this:
[code]....
I put a breakpoint in the propagate method, but it doesnt stop there. The page does post back (it flashes), but the event doesn't get called.
Here's an odd one that I've never seen before. Only on IIS, not in Cassini but in all web browsers I have a button that posts back and the page_load event fires, but the actual button click event doesn't fire. there is no re-writing of the page or anything else happening.
I get some URL from a XML feed. Now the question is how do I get a specific data from each page represented by those URLs. For example if I have a URL: [URL] in the feed data and on that page there is a table like this:
[code]...
Now the question is how do I get the content of the span which has the class "summary" and which is the child of the having a class name "snip". We do have to decode emove the encoded html contained by the span.
One site would take data from the site var. C# PostBack method.But when the page's source code as submitted does not renewed. Object Can not Be Coming Referanced error. So I do post but the page refresh itself. This post has been displayed next to new data coming from the user how can I get?
I wanted to know whether this is possible or not. I have a page with a div. I populate div at run time with a HTML table I wanted to access that table to get the data back.
I am trying with ParseControl() method... Not success Yet.
So I thought that you could use id="name" and access this just like an ASP control such as <ASP:Checkbox
or <ASP:Label etc. My code continues to caugh and state object not set to an instance of an object when I uncheck my checkbox
Line 741: ElseIf Not Me.CheckBox1.Checked Then Line 742: Dim row As GridViewRow = gvLink.SelectedRow Line 743: Dim recip As HtmlAnchor = TryCast(row.FindControl("recip"), HtmlAnchor) Line 744: Response.Write(recip) Line 745:
I've a grid view which could have huge data. When any control like a button causes the postback, I do not want gridview data to post back as it is not required and results in slower responses.
post - postid(pk), topicid(fk), post (content), createdby, createddate, updatedby, updatedon.
As i told in my last post, I am designing a forums website. I am not able to design the query to retrieve the topics for a category for example say catid=1. I want to display it in a grid view as done in every forums.
I made some query :
SELECT Topic.Sub, Topic.CreatedBy,COUNT(Topic.viewers) from topic where catid=1
group by Topic.Sub,Topic.CreatedBy
This is for retrieving the topic name from the subject and the createdby giving the topic starter and the total no. of views of that topic.
Now i want to make a query from the post table displaying the last post in the topic and if the post does not exist, i want to display the 1st post from the topic table as the last post done.
i have 3 dropdownlist, they are populated in cascade, dropdownlist2 info depends on dropdownlist1, and go on, i put the autopostback = true to the dropdownlist1 and dropdownlist2, but when i tried to select a diferent value in the dropdownlist2, it comes back to the first element, of course, i am doing a postback, the dropdownlist1 populate, and the dropdownlist2 datasource depends on the dropdwonlist1.selectedvalue, and put the same element no the last selected.
I have two web forms. One (Form1) with dropdownlist and button. Second (Form2) with the textbox , button and gridview.
I have the product list about 10000 items. When user go to Form1 and click the button. It will go to Form2 in which user will type the text in the textbox. And then click the button for filtering the productlist. the result will show in the gridview which will have select button in the first column.
When user select the product, Form2 will close and go back to Form1. The selected product will put in the dropdownlist in Form1.
How to do in the coding?
(1) Select button in the gridview with closing Form2, selected product put in the drop down list in Form1.
I have a web form with usual elements (first name, last name, etc). The Postback URL is a different website altogether as the form is intented to post lead information to another website.
The site that accepts the lead is expecting First Name to come over as "FName", and Last Name to come over as "LName". Is there any way I can set the ID of a textbox to "txtFName", but submit it over the wire as "FName"? I tried changing the name attribute, but at runtime it sets the name = id.
