Forms Data Controls :: Filter / Refine Datalist Further By Clicking On (Dynamic) Links
Jul 5, 2010
Let's say I passed a couple of querystring to populate my datalist on another page. Then I want to filter/refine that datalist further by clicking on links( which are dynamically created depending on the data on the datalist) and when clicked will pass another querystring to create a new refined datalist.
Example: I clicked on a link that redirects to [URL], a datalist will be produced on another page. Then there is are link on the same page that go to [URL], [URL], then another datalist will be produced. how to code these links, what I have in mind is link (4), link (10). The numbers represent how many records it will display if that link is clicked.
I have created a website that has some gridview controls that call stored procedures in a SQL db and display the results of the procedures. Two of the gridview controls have sorting enabled, and one has pagination enabled.
The site loads for all users who have tried it so far.
However, one user gets a "webpage not found" (HTTP 400 Bad request) error whenever they click on the pagination links or sorting links on the gridview control. It seems like it's not a security issue because the website runs as a user with permission to the database.
i have a problem with my asp project.i have a gridview that is created dynamically and all rows cells contain hyperlinks that are created dynamically also
all i wanna do is after clicking at any on this hyperlinks i can get the index of the cell where this hyperlink i clicked exist or even the text of the hyperlink i clicked but i don't know how i can do this
The eventhandler for the hyperlink is as follow:
[Code]....
i write in this code selectedrow.cells[0] but this is not what i want.What i need to replace 0 with the index of the cell i clicked
I have jquery menu in index.aspx page when user click on item related to that item it go to House.aspx and show products information in datalist these are my table in DB:
1-House_info Table
Id Behcode Name Region H_name
1 1111 Jack 1 Cloth 2 2222 Ana 1 Electric 3 3333 Edvard 2 Electric 4 4444 Math 1 Furniture
2-House_product Table
Id Behcode Name Description H_name
1 2222 Iron Test Electric 2 4444 Sofa Test Furniture 3 1111 Scarf Test Cloth 4 3333 Laundry Test Electric
And these are my code in index.aspx and House.aspx
string Code = Request.QueryString["H_name"]; SqlCommand _cmd = new SqlCommand("select * from House_p where H_name=@H_name", _cn); _cmd.Parameters.AddWithValue("@H_name", Code); _cn.Open(); SqlDataReader _dr = _cmd.ExecuteReader();
[Code] ...
EX : In index.aspx When user click on Electric item it go to house.aspx and show all product that have H_name=Electric According to House_p table it will show :
Id Behcode Name Description H_name
1 2222 Iron Test Electric 4 3333 Laundry Test Electric
Now I have one DDL and 1 button in House.aspx page I want when user click on menu and go to house.aspx page after they see result of their selected item from menu choose their region from ddl and click on button after that they see product that are in that region according to table House_info
EX : If user select region 1 it will show all Electric product that have region=1
how to implement a filter feature like this? What Ajax or JQuery controls can be used for this (if any)?
Here is an example of how the UI might look like:
See the Exchange Management Console image:
[URL]
Here is the spec:
The ASP.NET page has a "Filter" component and a "Apply Filter" button. The "Filter" component consists of 4 UI controls as below:
1. A dropdown list with prepopulated values like "Name", "Department", "Building", "Email Address".
2. A dropdown list with four operators - "Equal", "Not Equal", "Like", and "Not Like"
3. This is a dynamic control. It could be a textbox or a dropdown list. If the user chooses "Name" from the first UI control, the third UI control will become a Textbox. If the user chooses "Department" from the first UI control, the third UI control will become a dropdown list with all departments within this company pre-populated.
4. A button with AND expression. If the user clicks this button, one more Filter component will be created.
One possible user case is like this:
ASP.NET: when the page is loaded, it displays one Filter component (3 UI controls and a AND button), a "Apply Filter" button, and an empty "Filter Result" data grid.
when i open home page and click a link in whatsnew section, IE 8 opening the links in a new window.but firefox 3.5.7 opens in parant window, just like i want.how can i make IE 8 also open the links in parent window?
I have successfully implemented article - "Print only the items which are selected using checkbox in a ASP.Net DataList control"
I would like to add a dropdownlist above the DataList Control to filter the contents of Datalist and then print the items selected using Checkbox in a ASP.NET DataList Control.
My question is I have multiple Checkbox Lists and i want to compare it and Filter Datalist records on Checkbox list checked event.. (I want filtering something like [URL]
using System; using System.Collections.Generic; using System.Linq;
[Code].....
My problem is If first checkbox list is checked and user clicks on second checkbox list then i want to compare both checkboxes and populate result based on both checkboxes.
I must create a few DataLists programmatically. All of them will share the same ItemTemplate. Is it possible to define this ItemTemplate in .aspx file, using wizard etc, and then create DataList programmatically and assign this template? There is information in the internet how to define both ItemTemplate and DataList programmatically, but I want to define the ItemTemplate statically and only DataList programmatically and then assign the template to it.
The problem that I encounter is that ItemTemplate tag only works inside some control tag. It looks like it is impossible to define an ItemTemplate (like e.g. resource in Silverlight) not associated with any DataList, using the wizard and design tools, and then reference this template in code during runtime.
How to dynamically assign a datasource to a DataList ?????????
For example suppose that we want to fetch data from the database table accordingly user interest and then bind the data to DataList Control........... How to do that?
I have a form with a bunch of checkboxes and textboxes. There will NOT be a "save" button on the page. What is the best way to save the work when data is entered in the textbox? I can do the checkboxes on a click changed event but how do I save data with the textboxes??
As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.
I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.
I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.
Example site: [UL] In the left hand part of the page(refine result pane), how can I produce links/list like that? What control is used in that?? I know it has to use the data queried on the first page.
I have a web page that loads in user-defined text from a database field into a label. This text may or may not contain HTML links (standard <a href> tags). I need a way to enumerate through the links and enable/disable certain links based on whether or not the person viewing the page is logged in or not (via a session variable).The html tags include a runat=server attribute and the text is standard formatted HTML. Since the text is being loaded into a label straight from the database, the links aren't loaded into the controls collection for the form - so, I'm not able to reference the links that way.
I want to know which code or technique is used to write the code written below in url which is "3rhgf6v4zbos16x" what is this and how it can be generated in asp.net?
