Forms Data Controls :: How To Make A Repeater Clickable
Apr 19, 2010
I have the below code in a user control used at many places in my website.I want the whole control to behave as a hyperlink and redirect to the 'Testimonial page'.How can I accomplish it?
My doubt is how to make a list of titles of the news contained in a database. And this list each of the titles when clicked is redirected to a page where you will be able to view the news in full (Title, Body, Author).
What I got:
- A database containing a table with the news, every news is associated with an identification code (ex: "ID").
- A page where you will make the listing. (Ex: site / listofnews.aspx)
- I have a page that uses the method "querystring" to know what is the primarykey the news. (Ex: site/shownews.aspx?ID=12345, where "12345" is the primarykey of the news. Once it knows what is the primarykey of the news in the database, it loads each of the fields of the page (news.aspx) with the news, this part is working ok.
- The data is retrieve using the Linq, so I receive a List of "News", the class "News" as ID, Title, Body, Author.. My doubt is how to make the listing clickable.
In php I used this method (make a list of html links, in each link the href field is changed so that the tag "id" coincides with the news):
I generate dynamic grids based on a count value returned from some DB tables. the code for it goes like this : I give and Id to each grid that is generated.
if (myDataList1.Count >= 1) { for (int i = 0; i < myDataList1.Count; i++) { //retrieving the exact i count from pageload ViewState.Add("newCount", i); //creating the dynamic grid with its corresponding gridview properties. grvDynamic = new GridView(); grvDynamic.ID = "GridView" + (i+3); grvDynamic.AutoGenerateColumns = false; grvDynamic.RowCreated += GridViewRowCreated; grvDynamic.RowDataBound += grvDynamic_RowDataBound; //adding bound field columns to retrieve data from stored proc BoundField metric = new BoundField(); metric.HeaderText = "Goal "; metric.DataField = "metric"; grvDynamic.Columns.Add(metric); BoundField mtd = new BoundField(); mtd.HeaderText = "MTD"; mtd.DataField = "value_MTD"; grvDynamic.Columns.Add(mtd); BoundField goal = new BoundField(); goal.HeaderText = "Tier Level Achieved"; goal.DataField = "value_goal"; goal.HeaderStyle.Width = Unit.Percentage(10); grvDynamic.Columns.Add(goal); BoundField you1 = new BoundField(); you1.HeaderText = "Month End"; you1.DataField = "firstLevel_you"; grvDynamic.Columns.Add(you1); BoundField you2 = new BoundField(); you2.HeaderText = "Month End"; you2.DataField = "secondLevel_you"; grvDynamic.Columns.Add(you2); ButtonField singleClick = new ButtonField(); singleClick.CommandName = "clickHyperlink"; singleClick.Visible = false; grvDynamic.Columns.Add(singleClick); BoundField metricId = new BoundField(); metricId.HeaderText = "Metric Id"; metricId.DataField = "metricID"; metricId.Visible = true; grvDynamic.Columns.Add(metricId); //binding the gridview to data. grvDynamic.DataSource = data; grvDynamic.DataBind(); grvDynamic.Columns[5].Visible = false; } }
protected void grvDynamic_RowDataBound(object sender, GridViewRowEventArgs e) { //this basically gets the metric Id's of rows with the ishyperlink flag set to 'Y'. I need to make these particular cells clickable var isClickable = (from md in myDataList3 where md.IsHyperLinkFlag == 'Y' &&
md.value_MTD != null select md.metricID).ToList(); if (e.Row.RowType == DataControlRowType.DataRow) { // Get reference to button field in the gridview. LinkButton _singleClickButton = (LinkButton)e.Row.Cells[5].Controls[0];
This code works perfectly fine , depending on the ishyperlink flag in the database...specific cells in the grid are made clickable and then redirected to page2.aspx My Issue: I need to capture which specific cell in which specific grid the user has clicked. store some information in sessions based on the cell clicked and use that information in page2.aspx.
I have big problem to make this FlashAdRotator clickable to Navigate to an URL when using a Flashfile (.swf).
I wonder if it is possible to do any basic ASP.net embedding of the FlashAdRotator to make the embedded control clickable ? I will pass a URL through Session Variables to the clickevent later to open up an URL so I beleive <a href="index.htm"></a> wont work here.
I want to make an array of buttons. What would be the syntax to make the buttons clickable and tell it to do a specific function like copying the data to the system clipboard?
I'm using the asp.net menu control. It's working great, but I'm trying to figure out how to make the area around the text in the menu clickable? You see, some words in the menu are much longer than others, and I don't like it that the user has to move their mouse to the left to be able to click on the word in the menu just because it is shorter. Is there a way to make the entire menu item clickable? My menus are across the top of the page Left to Right, and then they drop down. And it's in that dropdown menu that the text length varies.
I am developing a movie database, in that i have autpcomplete with image feature for the users to search film titles. In that when the text box suggests the film titles with image if the user clicks the film title the title text is copied into the text box and if we click the search button then only it is redirecting to another page, my requirement is when the suggestion comes and if the user clicks a particular suggestion the page has to be redirected to another page and there i have written code to fetch details of the film from the database. I have used web service and the code is
<%@ WebHandler Language="C#" Class="Search_CS" %>
using System; using System.Web; using System.Data.SqlClient; using System.Configuration; using System.Text; public class Search_CS : IHttpHandler {

I know it has something to do with how my findcontrol code is written, but I can't figure it out.
I got this problem that I'm trying to repeat an imagebutton inside a repeater so I can add an command argument to it... But the image butten fails and I can at the most get it to write "Subit Querry" att the fields where I'm trying to get the images to appear. I havent that much usefull code for this after trashing the most in frustrations. but this is what I got.

I have a table being generated in an ASP.net web app. The table has 4 columns. Currently each cell of each row can be clicked to get more detailed info. However, I do not want the first and the last cell in each row to be clickable. How can I make it so that only the first second and third cell can be clicked?
I have a Datalist.In the ItemTemplate I add an asp:label and an image (img). I want both controls to be clickable as one Item so I put both inside a LinkButton.The result was strange I got only the Label clickable and fire the Datalist ItemCommand event ? how to make both works as one clickable Item ?
I have a GridView which is linked to the database via SqlDataSource.
What I would like to do is to make each row of a designated column clickable. Once the user has clicked on a row, the application should postback to another page to allow the user to read all the details of that row.
The effect should be as we can see in this post: if you go to "mypost", you have a list of posts and then when you click on one of them you are able to see the details of that.
I read lots of posts that are using, however, other methods such as datalist + dataset controls etc.
I have a gridview that includes a checkbox colum (Item Tempate).I need to be able to select row but when mouse is over checkbox column it should not be clickable. Is this possible?Think of it as an Inbox type gridview where checkbox is used for deleteing messages but when you click on subject or name it will show the message. I need the same functionality.
I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
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.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
I'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:
[code]...
I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
