As a newbie coming from a Java background with tag libraries I wonder if there is a simple possibility to render areas depending on backend values.For example if I have search form I do not want to render the table for the search results as long as the user hasn't pressed the search button. Of course I can iterate over the model containing an empty list but this does not allow to suppress rendering the whole table.Using web forms I would just control the visibility of the affected tag(s) in the code behind file but how do I do this with ASP.NET MVC?Can I use a partital view for a case like this? But I think I would have the same problem. How can I determine if a partial view is rendered (e.g. the whole result table with header)?

I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Below is my code
<asp:GridView runat="server" ID="gridManageClients" AutoGenerateColumns="False" OnRowCommand="gridRowCommand">
<Columns>
<asp:BoundField DataField="Clientid" ItemStyle-Width="75px" />
<asp:BoundField DataField="ClientName" ItemStyle-Width="300px" /> [code]...

I'm working on a asp.net forms web application where I've got advanced search form with grid listing results below. Grid is sortable and pageable. Grid is listing products.
I've got two requirements :
1) make the url remember the advanced search form state so search results page can be bookmarked etc.
2) on the product details page there is a back button that should take the user to the advanced search page with the same settings in the form and same grid state.
I have implemented a workaround to above two problems but I don't think my solution is very clean and I'd like to hear better ideas. My workaround is as follows :
1) I iterate through form fields and I put values into the querystring after the hash. So when the page is loaded it gets the values from url if available.
2) when user clicks a link to product details page from the grid I use javascript to create a cookie with url to advanced search page so when rendering the product details page I know the url for the back button.

I would like a gridview (using entitydatasource) to display the search results based on values provided in textbox txtSearch and dropdownlist ddlsearch. My search controls are as follows:
[Code]....
My entitydatasource is:
[Code]....
My gridview is written as:
[Code]....
Codebehind file contains:
[Code]....
I am a newbie at entitydatasource and have a few questions:
1. Currently, the gridview doesn't render. Why is that?
2. How do I wire up the gridview to grab the values of ddlsearch and txtSearch and return results using those values from my entitydatasource?
3. Ultimately, I want to encapsulate this gridview in a wizard step wherein the user checks items they want and those checked items are used in the next wizard step.

I have a .net page in which i have a search button which populates the data in gridview. On Headder row of gridview i have a filter image button and when user clicks on it i need to have a div tag opened as popup and in which i have to load the data of first column data of grid view as list of checkboxs and when user clicks one by one the parent gridview need to be shortened out (reduce) basing on selected/checked item in div tag. Since the check box controls are added dynamically it need to happen in Page_PreInit, so what i am trying to do is on the search i am trying to post back the page which goes to the Page_PreInit and tries to create all these check boxes dynamically.

I'm developing a search page that will display the results in a gridview. The codebehind (in VB.NET) uses a SQL command to fill the gridview.
The gridview does have paging and sorting enabled. Once the search button is clicked the initial results are displayed, if the user clicks on a sorted column or wants to advance a page the gridview disappears. Enable Sorting And Paging Callbacks is set to True. Enable ViewState is also set to True.

I am trying to create a search page, this allows the admin to search through the entries in the database by certain criteria, such as province (like state but diff country)
Here is the code I have so far. The problem is that I am not getting any errors. But I am also not getting any results. The page just posts back and returns to the blank search page. The GridView does not display any results.
here is my code as it stands:
Imports System.Data
Imports System.Data.SqlClient
Imports System.Web.Configuration
Partial Class administration_Search
Inherits System.Web.UI.Page
Protected Sub ProvinceButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ProvinceButton.Click
'get the search string from text box
Dim Search As String
Search = ("%" & ProvinceButton.Text & "%")
'if the string has value then continue with search
If Len(Trim(Search)) > 0 Then
Dim con As String = WebConfigurationManager.ConnectionStrings("fubar").ToString()
'build sql string
Dim s As String
s = ("SELECT id, surname, name FROM orders WHERE province like @strSearch")
'declar connection
Dim c As SqlConnection = New SqlConnection(con)
'add command
Dim x As New SqlCommand(s, c)
'add parameter
x.Parameters.AddWithValue("@strSearch", strSearch)
c.Open()
Dim r As SqlDataReader = x.ExecuteReader
GV.DataSource = r
GV.DataBind()
c.Close()
Else
Province.Text = ("Please enter search terms")
End If
End Sub
End Class
On the .aspx page I have a textbox (id: province) and a button (id:submit)

I am trying to export a gridview that is returned from a search form. The gridview also has paging enabled. In order to export the records from all pages in the gridview I had to turn off paging and do a databind, but instead of only exporting the search results it exports all the records in the gridview.
How can I only export the records from the search results, but also the make sure the records on the different pages export also?

i have some text boxs in a page and in the same page there will be a table 'grid' like for holding the search result.When the user start editing and of the textbox above, the search must start by sending all textboxs values to the server 'ajax', and get back with the results to fill the below grid.
Notes:This grid should support paging, sorting by clicking on headers and it will contains some controls beside the results such as checkboxs for boolean values and links for opening details in another page.
I know many ways to do this some of them are:1- updatepanel around all of these controls and thats it "fast dirty solution"
2- send the search criteria using ajax request using JQuery post function for example and get back the JSON result, and using a template will draw the grid "clean but will take time to finish and will be harder to edit later".
3- ....My question is:What do you think will be the best choice to implement this scenario? because i face this scenario too much, and want to know which implementation will be better regarding performance, optimization, and time to finish.

I have a survey form, survey.aspx, that looks for information about 3 different people (hiking guides) who are all contained in a single DropDownList. Instead of repeating the list over and over, I figured I'd put them all into a single user control, GuideList.ascx, shown here.
[Code]....
The form has 3 instances of this User Control. Here’s what the first one looks like:
[Code]....
In trying to access the value the user chooses from the DropDownList, I have created the following code
in GuideList.ascx.cs
[Code]....
In Survey.aspx.vb, I have the following, that often blows up because it doesn’t like G1:
[Code]....
I have tried using GuideList1 and GetGuide and GuideList1.GetGuide and GuideList1.G1 and all sorts of variations, but cannot seem to figure out what I'm missing to access the value of the DropDownList.

I need to create a user control which will be loaded according to the selected value of a dropdownlist. The Dropdownlist is not the part of Control. I want to pass the value of selected value of dropdonwlist to my user control and the user control will load according to the Value. For not postback it work fine. But when the page is postback, that is when i select a item form dorpdownlist, the user control is not loaded.
