I am familiar with creating and persisting dynamic controls on the first load of a page and on subsequent postbacks but I am having trouble with the following user initiated scenario...
In my demo I have a placeholder, two buttons and a literal
[code]....
I have two text boxes for the user to enter UserName & First Name, both these fields are optional and not mandatory to fill.
once the user presses the Search button, i execute the following query to fetch matching records.
[Code]....
The problem is, in cases where User leaves both the textbox or one of the textbox empty/blank, in that case that particular field should be removed from where clause.
More like if something is entered then search for that particular record otherwise search for all the records.
how can i generate rtf file based on input field(textbox input by user) c#
View 3 Replies could u tell me add controls to a page base on user inputs,
i know the basic of creating a button dynamically but here I have to to add few controls based on user input and how to identify event for each dynamically create control.
I have five textboxes(tb1, tb2, ... tb5) on the page, each textbox represent a column in the database table.
I need to search the database table based on the text in the textboxes. User can either enter text in all five textboxes or none.
What's the best way to do a search?
I am thinking for one textbox(tb1), depends on if tb1.text is empty or not, I need to do 2 searches
[Code]....
for two textboxes(tb1 & tb2), depends on if tb1.text and/or tb2.text are empty or not, there are 4 combinations, so I need to do 4 searches
[Code]....
for three textboxes, there are 8 combinations,
Does that mean for five textboxes, I need to do 2 to the power of 5, 32 combinations, 32 if statements?
I want to know that how to render partial view based on where the user navigates. I mean to say if user navigates to Home/index it will load different partial view and if user navigates to Home/contact it will load different partial view on the _layout page.Â

I have an existing application of 20 equal user controls. Each user control contains a complex calculation. I have 2 lines visible as a start and when activating line 2 then line 3 becomes visible, when line 3 is activated line 4 is visible and so on. However this results in a very slow application! So instead I would like to dynamically load the user controls one by one.
So my question is: How do I load the user controls to the website by raising an event?
My existing code in html is:
Code:
<uc1:HeatSimpleLine ID="HeatSimpleLine1" runat="server" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine2" runat="server" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine3" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine4" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine5" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine6" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine7" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine8" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine9" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine10" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<!-- 11 til 20 -->
<uc1:HeatSimpleLine ID="HeatSimpleLine11" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine12" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine13" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine14" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine15" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine16" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine17" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine18" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine19" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine20" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine21" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine22" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine23" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine24" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
<uc1:HeatSimpleLine ID="HeatSimpleLine25" runat="server" Visible="false" OnClickUserControl="HeatSimpleLine1_ClickuserControl" />
instead I would only have the first to user controls visible and loaded and the loading the user controls as I need them for improving the performance of the application and thereby I will not be limited by only 20 user controls in the application. add example codes
Setup:
My page has a drop down whose values are dynamically populated. Based on which item is selected, a number of TextBoxes are dynamically created during runtime.The user then fills in information into the textboxes and clicks a submit button.
Problem:
After postback from the submit button, I need to again dynamically create the TextBoxes during Page_Init (BEFORE LoadViewState) so that after the ViewState loads, my Button_Click event can save/do whatever with the user input. PROBLEM is, I cannot recreate the textboxes based on the selection in the dropdown, because the dropdown hasn't been "selected" yet by LoadViewState.
SO, how can I read from the view state, create my textboxes, then let the viewstate populate the textboxes, and then the Button_Click will use the values??
The one thing I've attempted is to override the LoadViewState function so that I can read from the view state, create the boxes, and then load the viewstate again. This did NOT work, because the debugger never seemed to hit my overridden function.

Im working with asp.net web application,I need to get multiple gridviews dynamically based on the count (which i get from database) for that i took a web user control and i added a gridview there . iwant to load that usercontrol in aspx.cs based on the count..
but im able to bind only one grid view...
What i am trying to achieve is that there are 7 columns in my db table. one is primary key and rest 6 are integer columns. Now my application will allow user to input 6 values. I want to compare 6 values entered by user to those 6 integer columns and if in any row 3 or more columns match user's input Primary key of that table is returned..
I have tried using queries, cursor, nested loops and i am still unable to achieve my results..
DB Table Structure.. I am inputting 2,3,7,11,45,65. Number of returned rows should be 5. eg..
UID A1 A2 A3 A4 A5 A6
-----------------------
1 2 3 4 5 6 7
2 2 3 4 55 56 57
3 65 11 45 66 67 68
4 45 7 11 99 98 97
5 7 7 7 7 7 7
6 7 7 7 7 7 7
7 8 8 8 8 8 8
8 8 8 8 8 8 8
9 45 45 0 3 1 2
10 65 7 4 0 0 0
IDs returned should be 1,3,4,9,10
I have a TextBox entry field where the user will enter a integer value. And then there is a "Create" button, which when clicked upon must generate a Table with 2 columns :
"Name" and "Email" being the column headers.
I want each row to have a textbox in each of these columns.
All of this has to happen after the button is clicked. I have discovered that if you dynamically add a control in ASP.NET(I am using C#) then the controls are lost during postback. And I don't know how to prevent that from happening.
Can somebody give me some ideas regarding how to go about adding rows dynamically to a table (I tried using the asp.net Server side table control but ran into the "lost-during-postback" problem - can I try with something else like a gridview ? but afaik a GV will not work without data bound to it )
Point to note is that my table has textboxes for user entry and it is not for showing data ..rather it is for accepting data from the user which will be later used to persist details to the database.
we are creating a custom content management and out portal page is bit bulky it is about 60Kb without images.
and during loading the page in some browser we can see some parts of site load faster than the other parts of the site where as we want to indicate (or instruct the web server) to load some of the areas first then load rest of the page.
is there any particular setting in IIS for is there any particular method in classic asp for doing that?
also I have the same question in asp.net.
I have form in ASP.Net 4 (C# backend) that a user fills out to enter a new game quote into my DB. I have created the form and this lets the user add only a single quote at a time, what I would like to do is give the user a drop down box to let him/her choose to add up to 5 quotes at a time. The problem comes in how to generate the extra input forms based on what the user chooses. I have been going over my ASP.Net 4 book but it really does not cover this.
View 2 RepliesI'm working with dynamic fields in ASP.NET due to a very specifc and rigid end-user requirement that would take 2 hours just to explain. Suffice it to say, I can't make the requirement go away.
Anyway, I have a working solution in place; no problems with controls loading, rendering or maintaining their ViewState. This is what my OnLoad looks like:

View 1 RepliesI'm designing a web page that allows a user to enter previous employer information. I'll need the ability to add multiple user input sections to capture information for each previous employer. Is there a user input control I should use to do this? Is it possible to add additional controls or user input sections when a user clicks on a button?
View 3 RepliesI'm creating a page that allows the user to create a new object that will later be stored in the database. The problem is that the design of ASP.NET data controls seems to insist upon only working with pre-existing data that has been stored in a database (or XML, etc...).
I'm basically trying to get the user to compose a list of items and specify a quantity for each item. I could do this by generating table rows but the rows are lost at each postback. The data view controls seem to be designed only to be bound to a data source but until the list is complete, the data can only be in memory.
What control is appropriate for this and how can I achieve this with that control?
We have a requirement of creating an input page which might be different for different users, changing will be in terms of number and type of fields. How should I architect this page. Should i create page using "XML and XSLT" or "XML and database fields" or is there any more flexible way to create this type of page. I couldn't visualise the flow in which this should be implemented.
View 2 Repliesi have a list of fields that i would store for all the user session. I thought to create a class, insert the information in it and store the class in the session but i'm not sure this is the best way to do it (performances, etc). I should have a list of these informations that i can display in views, i can delete and i can update. How could i do this?
View 10 RepliesOn page load is there a way to enumerate all the nest user controls for that specific page load?
I'd like to be able to enumerate all the user controls that implement an interface, and call the interface method for the controls before asp.net passes control to thier page_load events.
The problem is from the master page level, any page in the app could be loading, and each of them could have any random user control, and I need the type reference to determine if they implement the interface, and to call the method.
Iam building a website and i need to store somehow some informations that i will use in the whole site depending of the user type logged in.
Example:
1) User XPTO logs in
2) Query DataBase to see where he belongs
3) Store those 2 or 3 fields that i will get in Database in a persistent way to use it in the whole site.
Whats the best practices to do this?
When a user logs in into my website I have a custom membership provider that overrides ValidateUser and verifies that the user has sufficient rights etc.
However, when implementing a 'remember me' function through the default forms authentication using RememberMeSet, I also want to validate a user on the first request.
Is there some hook I can attach to that triggers when a user logs in with their persistent cookie?
