Forms Data Controls :: Dynamically Filling A GridView With HyperLinks?
Jan 20, 2011
I need a GridView with 6 columns, one of which ("ItemID") is a HyperLink who's URL and text is determined from the C# code as I will get that data from an SQL database
INITIALLY, what I wanted to do, which would have been easy as pie, is:
[Code]....
HOWEVER, this does not work because every row in the Item ID column is filled with "System.Web.UI.WebControls.HyperLink". Apparently, this is what the HyperLink's toString() method returns. Apparently, you can't just throw a HyperLink into a DataRow and call it a day. I need to know how to make this ItemID column into such a HyperLink. It doesn't necessarily HAVE to be a HyperLink control, it just has to be able to call my javascript function on the aspx page, "popUp(URL)"
To give you a visualization of what I'm trying to achieve: this is a change log for an inventory system. The ItemID column indicates what item was altered. However, simply just having a number there doesn't say much, so I'm trying to create a link with the text, for example, "42 (motherboard x)". In other words reader["ItemID"] + " (" + reader["Description"] + ")", and that link will run a javascript function I have called popUp(URL) which takes a URL and opens it in a new window of specific size and location, to view that item's details.
I've tried various other methods such as disabling AutoGenerateColumns and manually create a HyperLinkField, but to no avail, because I couldn't get it to run my javascript function that way.
In a webform I have two textbox (txtDNI and txtAPE), 2 buttons (b1 and b2), 1 gridview (myGV) and 2 functions (dt1 and dt2) that return a DataTable txtDNI will be a parameter for dt1 function and txtAPE will be a parameter for dt2 function
When I press b1 myGV will be fill with the dt1 function's datatable and when I press b2 myGV will be fill with the dt2 function's datatable myGV allows paging=true and when I press the next index (2 or other) It appears a PageIndexChanging error. So the pagination isn't automatic and I have to code the PageIndexChanging event When I use a ObjectDataSource and I connect it with myGV the PageIndexChanging error dessapears and the pagination is automatic The problem is the ODS only have a one selectfunction (dt1 or dt2) but not both and the configuration is on design time
The same happen with the PageIndexChanging event where I fill myGV again (with dt1 or dt2) and set the new index (myGV.PageIndex = e.NewPageIndex) and What is the problem?? ... the problem is, for example, when the user erase txtDNI and change index of pagination ... the PageIndexChanging event is fired and call the dt1 function but the txtDNI(parameter) is empty and occurs an error, the function returns an empty datatable and myGV is empty too for avoid this I create viewstates variables for each function, so I have a 2 viewstates and fill them when the user press b1 or b2 When user press the pagination, the PageIndexChanging event catch the viewstate variable and convert it into a datatable and the problem of the automatic pagination is controled The problem is I don't have 1GV in the webForm I have 5GV in some pages... and I try to avoid...
1. all the code in the PageIndexChanging events of each GV in the webform. 2. use the viewstate variables
I am trying to get a hyperlink to show up in each field of the "Title" column in the gridview below, but it doesn't render as a hyperlink:
ID Title City State
115779 <a href=job_details.aspx?jobID=115779>Online Advertising Inventory / Yield Manager (773044)</a> Washington DC 115801 <a href=job_details.aspx?jobID=115801>Administrative Assistant (778554)</a> Washington DC 115840 <a href=job_details.aspx?jobID=115840>20769 Deal Leads</a> Washington DC
I don't want to databind a gridview, I want to be able to add rows myself within c# code. I can see there is a GridViewRow object and wondered if I can use this to add/remove rows as required?
I have a gridview with a hyperlink control that allows the user to save pages to it (www.google.ca, asp.net, etc). Unfortunately it always adds the server name to the beginning of their link. [URL] I was wondering is there any way to change that within the control. or should I have it pass a query string to a url handler that will response.redirect them to their actual page?
In the following code i have to continuing showing the rows of the gridview as links. For example: the user will click on a customer and will see more detailed information.
protected void Button1_Click(object sender, EventArgs e) { //List<Customer> customersresult = new List<Customer>(); does not match the type here CustomerWebServiceClient.Customer[] cust; CustomerWebServiceClient.CustomerWebService client = new CustomerWebServiceClient.CustomerWebService(); cust = client.GetCustomerContract(TextBox1.Text); //coming across now.. //if (cust.va) validate if there is data GridView1.DataSource = cust; GridView1.DataBind(); } // this is showing the gridview with the data coming. What would be next steps to show the rows as hyperlinks.
we're creating a GridView to display news articles programmatically (not using a SQL database).
We can create & display the GridView, but are having a devil of the time to get the hyperlinks in SetupGrid() attached to the titles
of the articles in the GridView. Below is our .aspx code and .vb code of how we create the GridView. Any ideas on what we should do to get the hyperlinks array of strHyperlinks() in SetupGrid() to be applied to the titles in column 1 of the GridView?
I have a stored procedure (For Eg: sp_GetAvlData) that accepts a number of parameters, 3 of which are TimeFrom, TimeTo (as varchar) and TimeInterval (as int), formulates a Dynamic query and executes itself. So for instance, if I call the proc as follows:
[code]....
dtAvl is the datatable containing the results of my stored procedure.
The next step for me is to make each of the cells (except the cells in the first column) as a Hyperlink so that when clicked upon a cell, it populates 2 textboxes with the selected Timeslot and Name or ID (ID field is not displayed in Gridview). The textboxes are located on the same page but outside of the Gridview control.
The Challenge that I'm facing out here are:
1) As you can see, the field names being generated are not fixed and I have no control over them.
2) Because the field names are not fixed I'm not sure I can implement this using the Templatefields or BoundFields of Gridview.
Is there any way to achieve the Hyperlinking of these cells within the Gridview?
I have a requirement to create multiple hyperlinks dynamically in a single GridView Column. The number of hyperlinks are not not known in advance and will depend on the results brought up by a query. How do I create the same?
I am working with SSRS 2005. I was wondering whether there's a way to dynamically fill the data in each Drilldown table group (ie. when its expaned on toggle). So only those records for which a user has expanded will be filled and the collapsed group's data is not retrieved because it does not need to be shown. This way one can restrict large records coming to report thereby improving the execution time and performance of the report.
When I am trying to export data from gridview to excel i an also getting hyperlink along with that, how can i remove that before export. below is my code
<div align="right" style="padding-top:5px; padding-right:5px"> <span title="Export Data to Excel"><asp:ImageButton ID="btnExporttoExcel" runat="server" ImageUrl="~/img/Excel_Logo.png" onclick="btnExporttoExcel_Click" /></span> <span title="Export Data to Word"><asp:ImageButton ID="btnExporttoWord"
I have 5 link buttons in my asp page, i want to change the text property of the each of the link button to the data retrieved from my database table in th page load. To be more specific i want to display 5 latest film news headings in my home page and if the user clicks on a particular news heading i want to show that news details in a separate page with all the details related to that news.
I have file paths which points to a file which is stored in a database I cannot use the hyperlink control because it can be any number of paths can any one tell me how to create hyper link dynamically so that i can points to the file.
I have a set of images which needs to be displayed horizontally on the page. When the set of images reaches the edge of the browser window, they need to continue being displayed horizontally even if it means a horizontal scroll bar is made (In fact it will almost always result in a horizontal scroll bar forming).
I have tried to find some way to get images to push of the side of the page but can find no way (using basic CSS) without defining a width on a container holding the images (eg. 8000px). This is not possible as the width is dynamic (more or less images may be displayed as they are added to the database)
So my solution in theory:
I now record the dimensions of the image in the database when it is uploaded to the server. Using a repeater, if I add together the width of each image as they are loaded then I can use this number to define the width of the container. Seems to make sense right?
The problem comes when I load the images. I am not great at using the Repeater at the best of times and once again it has got me stuck. I have used the Repeater ItemCreated in my code behind but my variable which I declare (dim i as integer = 1) appears to get reset each time.
When I tried in Repeater OnLoad it didn't seem to work either.
The scenario in question can be found here: [URL]
You can see I have responsed the variable in the top left and they are all 1, hence why I believe the variable is being reset.
I was working on a fairly simple code to get RSS into gridview. The code works fine with the URL mentioned in code but unable to work on Commented one.
i have a table containing multiple agents , another three containing events ( three types of events , each category in a diffrernt table) organised by each agents! , i have to figure out how to fill a grid view that regroups a summary of the activity of every agent ! for example :
that means that the agent 1 have organised 3 EVENT1 0 EVENT2 and 2 EVENT3 ....
i have used the count(*) clause to fgure out the number of rows in table events referencing to each agent (group by) but it seems that value 0 is not returned by the clause , so i'm having a problem getting the exact values!
secondal , i have putted two calendar that will fix the beginnig and the end of the summary , but it seems that the end day is not included : it says 18/01/2010 00:00:00 and i have some events planned in 18/10/2010 14:10:00 so they are not counted !
I read a few VB books and ready or not, I going to start building!I am "very afraid" of code behind. Frankly, much of what I read about OOP went a bit over my head and am hoping by "doing" it will all come together. That said...
Datalist results. I want them to hyperlink to another page with a querystring. I moved a hyperlink control into the EDIT TEMPLATE box and removed the origianal label that was in the box. I did some editing and was able to come up with a hyperlink, but I really need a hyperlink to a new page with the original result of the datalist being the querystring parameter. For example...
If BABE RUTH is the datalist result, I want the querystring to be www.mysite.com?athlete=BABE%20RUTH. I am fairly competant in asp classic. I feel like a guy who has amnesia and has to learn the most basic stuff from scratch.
I created a datalist which contains hyperlinks that when clicked will redraw the page and update my another datalist in the same page. How do I hide this datalist after click any of its hyperlinks?
I need to create a display grid of picture cells 5 columns by rows determined by database select. Each cell to contain picture, title, name, phone number pulled from database. How do I create a table like structure and populate it? Can a DetailsView control be called into each table cell with the table row count being determined by the same select statement?
I have a Web User Control that is sitting in a Tabcontainer on a web page. The user control is on tab 1 and has a listview control in it. In the listview control I have a textbox called txtWorkOrderID. In tab 2 I have a gridview with a button in one of the columns. When the button is clicked I want to grab the ID from the row I'm on and fill the txtWorkOrderID with it on tab 1. I've got things to work as far as grabing the ID and switching back to tab 1, but I keep getting a null reference when I try to put the value into the txtWorkOrderID which tells me its not finding the control. I am using .netVB in VS10. how to reference the textbox in the control on tab 1. here is what I have so far. [Code]....
I need to programmatically fill DropDownList in FormView and can't find the proper event to do it. I keep getting "'GenreList' has a SelectedValue which is invalid because it does not exist in the list of items" or "Bind, Eval can only be used in databound control" depending on the event. Sample code follows (there's no attempts to bind a DropDownList there ):
I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:
