Web Forms :: Get The Value Of A Textbox In A Dynamic Web Control On Postback?
Mar 22, 2010I have one web control in a page.
Lets say i have a web control that has one <asp:textbox id="action" text="getArticle"> and one <asp:button ...>
If i press the button, a postback will occur but will not load this web control again but it is supposed to load another web control.
How can i obtain the value of the textbox. The issue is that the web control is not loaded so findControl("action") will return null.
What is the correct approach to handle this? Should i use url parameters? Is there another way.

Jan 25, 2011I have an ASP.Net Application that in some cases will create up to 100 or so dynamic controls that have events being triggered from CodeDom Assembly. The problem is when at an event is fired off I have to Re-Create all those controls on a PostBack. With 10 to 30 controls its not so bad but with 100 it takes approx 3 to 4 seconds before the user can resume filling out the rest of the controls.

Web Forms :: How To Hold Dynamic Controls On Postback
Mar 15, 2010I'm trying to create a page that will display a survey that has multiple pages... everything displays fine, but I'm doing something wrong on the timing as my dynamic controls (for the answers) are disappearing when I post back. (so I can't get the answers or perform validation)
1) I have a Repeater control on my page that is populated in Page_Load !IsPosBack that is acting as navigation. It displays each page name, and each Repeater Item contains a LinkButton whose OnCommand event does:
2) There is a second Repeater on the page that is populated with Questions corresponding to the selected Page (from the step above) This is just a DataTable created and then DataBound to the Repeater.
3) The Questions Repeater control has an OnItemCreated event that dynamically generates the proper control for the Answer (TextBox, DropDownList, RadioButtonList, etc...) and places that control in a Placeholder in the Repeater Item.
This all works for displaying, but when I attempt to click a Button, I cannot access the controls generated in step three, and all of those controls disappear from the Repeater.
I have tried creating databinding the Questions repeater in Page_Init as well as dynamically creating the answer controls in a (foreach RepeaterItem...) statement as opposed to OnRepeaterItemDataBound... but now my buttons (located in the FooterTemplate) refuse to post back at all...
added a Test button for postback, but that doesn't work either.

Web Forms :: Dynamic Controls Auto Postback (asp:radioButtons)?
Jan 11, 2011 I'm inserting controls dynamicaly on my page on pre-init, thease controls are inserting based on a dropDownList that load its values from a database. These values are diferent to all clients.
If I insert my controls on pre-init then I have access to the value of radiobuttons, but this insert only 1 controls cause in pre render I don't have the selected value of dropDown.
If I insert my controls on on-load event then I have the value of my dropDownList control so I can be able to inser the correct number o controls but I don't have the value of my auto-postback radioButtons.
I make a project to solve this and I share the code of it here. (VB.Net 4.0)

Web Forms :: Persisting CommandArgument After Re-Creating Dynamic Button On PostBack?
Mar 14, 2011I need some high-level advice on how to deal with this issue. I want to have dynamically created buttons, each with a different CommandArgument, that call an OnCommand event when clicked. Given that these are dynamic buttons, I have to re-create them in Page_Load after the postback. However, when I re-create the buttons, the orginal command arguments are lost, and the arguments generated after the postback are only valid.As you'd expect, if I don't recreate the buttons, the event handler is never called because the buttons don't exist.My question is, how can I retrieve those original commandarguments, without the use of sessions.

Web Forms :: Dynamic Controls Creation / Rendering Based On Postback Values
Nov 8, 2010I had successfully created a functionality where I can dynamically add rows and columns to a asp table by creating/re-creating controls on every page load.
I have 2 buttons - Add rows and Add columns that, basically according to a asp.,net page life cycle, occur in the following order and work perfectly fine.
Page load is fired and controls along with their viewstate are recreated. In Add row button click event - I just create a new table row and add controls to each cell dynamically.
Same thing with Add column, Delete Row and Delete Column button click events.
However, now I added a Dropdown which when its index is changed needs to retrieve values from the database and create controls based on those values and then also bind the Db values.
But it doesn't work correctly since the asp.net page cycle cannot capture the dropdown's selected value in page_load as the page_load fired first and then the selectedindexchanged event is fired later, the controls are not created.
I don't know how to handle this scenario and incorporate it into my existing code.
Forms Data Controls :: GridView W/ Dynamic BoundFields Disappears On Postback In IE Only?
May 4, 2010have an ASP.net 4.0 page containing a GridView, where during the Page_Init event I'm dynamically adding BoundField columns to the gridview. I also have some custom sorting and paging methods that I use with this gridview, which result in postbacks on the page. In Chrome, Firefox, Safari, and Opera the gridview behaves as expected. HOWEVER, in IE 6, 7, or 8 when I click to sort a column in the gridview, or go to the next page of results in the gridview, it does not bind on postback, returning nothing back to the browser. Again, in anything but Internet Explorer, paging and sorting (frankly any postback event) brings back the gridview in its expected state. I only have the problem in IE. Relevant snippets of my code follow, where you'll see my Page_Init event calling a method in my WebFunctions class to add the BoundField columns for the table I pass to it, and my Page_Load event that calls the method in the user control responsible for binding my dataset to the gridview. Initial page load works in all browsers, but postback loading of the gridview only works in non-IE browsers.

Web Forms :: Can't Find Dynamic Button's Postback In Page.request.form
Oct 8, 2010I know that dynamic buttons and buttons in general don't use a typical postback and they post through the page.request.form. Okay, so in visual studio, I was able to determine that page.Request.form and in the all-keys property, i SEE my button there. It is the last item in all-keys.
When I am clicking this dynamic button which is in an updatepanel, the script below does not detect it as a button, it is still showing it as null:
public static Control GetPostBackControl(Page page)
{
Control control = null;
[Code]....
but here is the kicker, when I am traversing through the object, I am looking at the object C and the property 'ctl'. The ctl is showing me a value of "ButtonRow_0Col0" and it is of type string. This is good! But , the 'c' control object still says 'null'.
Forms Data Controls :: GridView TemplateField Vanishes On Second Postback With Some Dynamic Content?
Dec 23, 2010(Example code below)
I have a GridView. It has a 'static' TemplateField (in the .aspx page). I add and remove BoundFields to it depending on user preferences on postback. Affter the second postback, the template field appears empty.
Here is a stripped down mockup of what I'm doing. You can click the "Regular Postback" button as much as you want, and nothing bad happens. But if you click the "Recreate" button once-- it's all ok. Click it again, and the "one" column goes on Christmas break.
So is there something else I should be doing, or is this going to be a "halcyon1234 to code interface" error.

Forms Data Controls :: Viewstate After Postback On Gridview With Dynamic Columns Emplate Fields?
Jan 13, 2010My datasource is an ado data table that I have convert to a new data table so that each row in the original table is now a column with 1 row in my new table. I then bind the new datatable and create dynamic template fields with a text box where I bind the values. My problem is, when I try and retrieve the values changed by the user in the rowcommand event, the template columns no longer exists.
Does anyone know how i can retrieve these values? I've read over and over that you have to rebind the grid on each postback when you use dynamic templates, but I'm not sure how to do that and retrieve the values entered in the text boxes on the client side.

C# - Persisting Dynamic Controls Over Postback?
Sep 30, 2010I have a datagrid that loads on page_load.
In this instance I can't load the datagrid in page_init as the results of the datagrid are determined by a checkbox and the checkbox would always be set to true during page_init to the viewstate not being loaded.
I have an OnItemDataBound event on the datagrid that dynamically creates controls and later on I want to access the value of some of these controls (e.g. a text box)
Of course the problem is I can't access these controls values as they don't persist over a postback.
