Web Forms :: Preserve DDL Values Among Several Pages?

Mar 10, 2011

I have a form, mostly consisting DDL's. I constructed this form using a Master page with about 10 different pages attached. Each page consists of roughly 10 to 20 DDL's. My goal now is to navigate from one page to the next and back with out loosing the selected values in each of my DDL's on each page. I have thought about assigning each to a Session but that would really bog things down considering the amount of Data i would be storing. I would love to go the easiest route but my mission here is most efficient.

Web Forms :: Pass Values Between .aspx Pages?

Mar 28, 2011

I've got a pretty simple problem but I am not sure what is the best way to accomplish this. I've got an input aspx where a user fills in about 15-20 input fields and I want to display this information on the next page however; I am not really sure what is the best way to go about doing this?

I tried using 'Server.Transfer' and 'FindControl' API calls but have struggled to use them because the value is always null because it cannot find the asp:textbox ID I have specified from the previous page.

What would be the best way to just simply transfer the values from my previous page to the next page??

Web Forms :: Inline Bind Hiddenfield Or Textbox Field

Dec 17, 2010

I have been at this for two weeks now without any success but I know I have to get a solution to move forward with my design. Is there any way to bind data from a SQLDataSource to a Hiddenfield or Textbox WITHOUT binding via the data controls like gridview, formview, datalist, etc. I do not want to use any of those controls. I need to do inline binding. Please provide the working code example. The hiddenfield or textbox would be named eid. The SQLDataSource name is GetDataEid. Again, if you reply and you submit code I can try please provide the full working solution. These do not work. They have already been attempted:

<asp:HiddenField ID="HiddenField1" runat="server" Value="<%#Container.DataItem("FieldName") %>" />
<input type="hidden" id="hdnId" name="hdnId" runat="server" />

and write the following code in your page load method

hdnId.Value=yourDbValue.ToString();
asp:HiddenField ID="hid" runat="server" Value='<%#Eval("column name") %>' />

C# - Passing Values Across Pages?

Apr 7, 2010

i need to pass a long list of Ids from one page to another, i was thinking of using querystring but taking in consideration that the number of ids to be passed may reach 300 i think is not a good idea.an option from my understanding may be the use of session, this seems to me an optimal solution in my case but on the other hand I can certainly clear the session when the user performs a certain action and the list of ids is not longer needed, but if the user leaves the page without performing any action i want to clear the session, how can i do it?f multiple users are using the same functionality do i need the session's items to be confused or the session is for a single user?

Web Forms :: Access Usercontrol's Hiddenfield From Content Page Code Behind?

Apr 21, 2010

I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.

I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.

alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.

I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.

objBLL.Latitude= DirectCast(uc_MyClient.PickupHidLat, HiddenField).value

why is the value null on the content page?

Forms Data Controls :: UserControl In Page / Hiddenfield In Each Is Not Empty?

Nov 2, 2010

I have a repeater which always has 1 UserControl, however the UserControl can vary, lets say it could be UC1, UC2 or UC3.

When I come to validate that a hiddenfield in each is not empty, I iterate through the repeater items but I have to do a findcontrol on UC1 check an exposed value, then do the same for UC2 then UC3. In all its a bit unwieldly.

What it would be great to do is iterate through the repeater items find the hiddenfield (which is the same name for each UC) and test that in one go, like below:

foreach(RepeaterItem item in Repeater1)

{
... some code here to start off with

HiddenField hfAnswer = (HiddenField)item.FindControl("HF_Answer");
if(hfAnswer != string.Empty)
do something here
}
