what can be the problem here?

how to get hidden column value in gridview in asp.net
View 3 RepliesI have a requirement where I have a webpart and two ImageButtons(imgGV, imgLV) and a hidden input textbox('ctl00$MainHeaderContent$txtType') in an aspx page. I need to change templates to this Webpart either to show results in "Grid View" or as "List View" on the click of this ImageButtons. I added code in the page_load of .aspx page as
imgLV.Attributes.Add("onclick", "document.getElementById('ctl00$MainHeaderContent$txtType').value='LV';return true;");
imgGV.Attributes.Add("onclick", "document.getElementById(('ctl00$MainHeaderContent$txtType')).value='GV';return true;");
When I am clicking the specific ImageButton, it has to write into hidden field either "GV" or "LV". In the webpart CreateChildControls I assign templates based on the text in Hidden field either "GV" (Grid Template) else "LV" (List Template). In the CreateChildControls of Webpart for the template change, I am getting the Hidden value as empty. I am using coding as
HtmlInputHidden t = new HtmlInputHidden();
t = (HtmlInputHidden)this.Page.FindControl("ctl00$MainHeaderContent$txtType");
if (t.Value=="GV") {
assign one template}
else { another template}.
I am getting t.Value="". Question is: Is it like if we add some text in a hidden textbox using the Javascript function in an aspx page, the same textbox value in the same aspx page but in the Webpart class in the CreateChildControls method using the code as this(webpart).page.FindControl("Textbox").text is showing empty. So the text added using Javascript into Textbox is it not available in the code behind code using "Text" property of the same Textbox?.
I've created an asp.net sitemap with nodes that I will have to make visible on the condition of the sql table the webpage of the node accesses.
Where is the code of my sitemap.
[Code]....
Here is the code I have tried.
[Code]....
Each time I run this code the item.target, item.value, item.text equals the sitemapnode title. Yet, it should be different than this. I was hoping to store the table title of the sitemapnode in the value property. The reason for this is to enable my boss to modify the sitemap without having to explore the C# code. I'm lucky that if I could get him to open the sitemapfile. He does not want to worry about the code breaking down when he makes an addition to the sitemap node.
I have found that I can change the value programmatically in C# but this would contrast with what my boss would want.
is there any reason for me to place the session ID within a form, as a hidden form field?
View 3 RepliesI have an asp.net page in an iframe where all links target _blank
<base target="_blank" />
But I want the form on it to submit to _self (i.e. the iframe where the page is located) when the one button is clicked. The form is an <asp:Panel> with an <asp:Button> control for submitting it.
Where can I set the target for this form? Since there isn't a <form> tag or an <input> tag in the file (ASP.NET makes them when it renders the page), I don't know how to change the target to override my <base> tag.
I am using IFrame in my ASP.NET pages. For the page that I am referencing in my IFrame, I have a gridview (I also have CommandField that referencing another asp.net page) and paging enabled.
I wanted to display a new page (outside of Iframe) when a user clicks on the commandfield in the gridview. In order to do that I set form's target to "_parent". This works fine (it open a new page outside of Iframe). Now, my problem is that when i click on the paging to go to next page in the gridview, it also opens the gridview outside of IFrame (which I dont want to happen). I want it to open within the Iframe.

Request.Form collection does not contain Form hidden field value.
Dispite what the topic subject says, I really want the opposite. I panel with a form and validations that's hidden. I also have another form that I'm trying to use on the same page, but the page won't validate because of that hidden form. Is there any way around this? Can you tell the brower NOT to validate just those hidden fields?
View 5 RepliesI have some code which is rendering some custom attributes of Hidden Control (without runat=server).
Something like,
<input type='hidden' id = 'hdn1221' name = 'hdn1221' OldValue = '12' OldMode = 'A' />
And I have a lot of these hidden elements on my form.
When I submit the form, I am looping through a set of ids, say 1200 to 1250, so I will read controls based on that, and also hidden with Request.Form["hdn<Id> "]
Now problem is, as we know we get value attribute from form when we do Request.Form["id"] for hidden, I want to read my custom attributes from hidden element. Is there any way? Note that, I can not touch the rendering part here.
I got a hidden control in a User Control, as follows:
Code:
<asp:HiddenField ID="workDateId" runat="server" Value="" />
The user control have a member:
Code:
public string WorkDateId { get; set; }
In the form load event for the user control I set the value of my hidden control to the value of my member:
Code:
workDateId.Value = WorkDateId;
I use the user control as follows:
Code:
var ctrl = (TestControl)LoadControl("TestControl.ascx");
ctrl.WorkDateId = "some nonsense";
var cell = new TableCell();
cell.Controls.Add(ctrl);
tblRow.Cells.Add(cell);
However, the value of the hidden control are never set. So..what did I miss?
I Have two pages source.aspx and target.aspx. Source.aspx has one button and other form controls the collect input. The button has its postbackurl property set to target.aspx. On target.aspx I have another button and other form controls that collect input. When the user clicks on the target.aspx button, I want the inputs from both source and target gathered to be inserted into the database. The problem is the Page.PreviousPage property is only available during the initial rendering of the target.aspx page. So when I click on target.aspx button, PreviousPage is now null.
One strategy of mine is to collect the information on page_load and store it in ViewState, but is there any other method that I should consider in this process. I think the cleanest approach would be to somehow access PreviousPage on the button_click event handler, but how can I access this property.
In order to use hidden input, does the hidden input must be inside a form?
Is there any strategy to perpetuate the hidden input value between requests? So far I guess it's through query string / URL?

I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.
I have a form as
<form action="" method="post">
<input name="Descripcion" type="hidden" value="" id="Descripcion" runat="server" />
<input id="Submit1" type="submit" value="Comprar" />
Instead of clicking on submit button i want that the form should be posted without clicking submit button with hidden fields

I am saving "Instruction" in CreateInstruction view. This view has partial view "CreateInstnAttribute" which saves "Attributes" related to this Instruction. It requires the InstnID as foreign key. The Instruction is saved using JQuery to avoid postback. So how can I get the InstnID to save the InstnAttribute? I tried HiddenField to save InstnId but I am not able to receive the value there. Can we use viewdata directly in JQuery?

I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?
Looking for sample to access the hidden variable which is declared in the aspx page in the webmethod.
