Using a GridView to display unique website department names from a database table, is it possible to create a hyperlink in the GridView to that specific departments page? I'm a beginner and haven't found any examples so unsure as to how this would be accomplished.
View 8 Repliesam using vs 2005 and sqlserver 2005.in my database table (name : users) there are more than 10 lac records.i have to display the user details in a grid.if i wrote the sql query as " select * from users" then it is throwing the "System.OutOfMemoryException"So i wrote the query using rownumber (i mean first it will get inly specified no of records ex:25 )so it is displaying only that 25 recordshow to give paging in this situation...?y requirement is in the grid i want to get and display first 25 records with the paging asirst Previous 1 2 3 4 5 6 7 8 9 10 Next Last
View 5 RepliesI have a asp.net gridview control on my page with several fields and a couple of command fields. However, the update command is giving me problems.
Here is what works. The update command works provided I put straight text into the textboxes that appear. I even have one field that contains a dropdown list which works fine.
Here's the problem. I have two fields that need to access their value programmatically. These fields will reflect the current datetime and the current loggedin user from active directory. I have already created public strings in the C# code.
When I run the edit command on the asp form the grid uses one "DataKeyNames" element. With this the grid can update the selectedrow. However, I haven't been able to access it programmatically in the C# code. I can access the selectedrow in the "selectedindexchanged" event but then I am not able to update my fields in the gridview itself. So, part one of my question is how to I access the "DataKeyNames" properties of a gridview control.
if I can't access the "DataKeyName" property perhaps I could set the label nested within the gridview to the "myCurrentUser()" public string. I am inserting my code to hopefully make this clearer.
I'm gonna outline the application roughly: it's a tool, where people can upload a CSV-file, which contains their data for some crazy water-plant-biology-stuff. ;) The job of the application is (besides others) to validate their entered species. So far no problem, I've got my string-array with the correct species abbrevations, and i can parse the species names from the user-edited CSV-file.Whenever a species is found, that is not part of the reference-array its being sent to a GridView as a new row. All of the above works fine - if anything isn't explained well, just ask.
Now, what I want to do is to give the user a simple edit-function: beside the WRONG species name, it would be terrific, if there was some sort of drop-down-list, filled with the correct species names (which are stored as a string-array in my .cs-file!). The user looks at his wrong species, then just has to select the correct name from the drop-down-list, either updates row for row, or even better: edit every row, and update once at the end. Is this possible? I remember that it's quite easy to fill template-fields with data through SQL-connections etc, but is there a more simple way to do it? As said, I've got a fine string-array in my .cs-file behind the aspx-page.Haven't found any code for this. Are template-fields in the Gridview the right way?
Which might be a solution for the updating-problem: I keep storing the wrong names in the rows, and just add another column next to the species name, where this drop-down-list should appear. Then i add a button, which, when clicked, gets the old value & the new selected value for each row, and updates the data. Should work? So the problem remains: how do I add a template-field with many (<500) items in the .cs-file to a GridView-Column?
I need to disable the edit command link if a record has links to other records within the tables.
I have a table that has worktype and that is captured when certain records are entered. So if a record exists with that value, then i want to disable the "Edit" link for that record within my gridview.
I want to provide them access to add more worktypes, but if they want to edit a worktype, i need to make sure its not used anywhere in the other tables, before they can edit it. For now atleast, because i will need to allow full editing and deletion functions for this table. how to do this or maybe suggestions on other things i can do to give them full functionality?
I want to get extra column with links in my gridview which changes on click and updates my database
View 8 RepliesI have a grid view (using sqldatasource & C#) which returns no rows. By design asp.net does not show header/footer. I looked at couple of sites and suggestions and found it to be too complex. Nothing was simple. The one I found was to create a empty datatable, insert rows and bind it to the gridview. But that code does notwork for me because I am using sqldatasource and using datatable gives error.I decided to just add the following to empty item template.
<EmptyDataTemplate>
<div>
<asp:Label Text="No details found." runat="server"> </asp:Label>[code]....
THe link shows up in the bottom but the event gridview_RowCommand is not fired as the grid view is not created or it does not have rows
How do I call a function on click the add new link and put all my code in there to insert possibly using a modal popup. I cannot use onclientclick because it is javascript.
I've this table Table1(ID , LinkURL , LinkText )
I would like LinkText to display as a link. And when you click it takes the value from LinkURL and directs you to another page.
This is the code:
<asp:GridView id="GridView1" runat="server"></asp:GridView>
And this is the code-behind:
connection.Open()

I need to display foders n files information(type,size,date modified etc) of a particular directory in a gridview.I need to make the folders as links and files as labels before binding the data.
View 1 RepliesI have a list of links displayed in a gridview that, when clicked, open in a new window. I used OnClientClick = "form1.target = '_blank';" to achieve this. I also need to let the users delete links. Problem is, when I click the delete button it calls the OnClientClick event even though it isn't in the delete tag. This only happens if I click delete after I have clicked on a link. The result is that the link I am trying to delete opens up in a new window and is not deleted.
View 4 RepliesI have been searching for some time on the net for guidance on this question. Finally thought I will ask here...
I have a gridview that needs to be generated from code behind. There is a column with a name field and the remaining columns give the different user-ids linked to that id. Like this:
-- NAME, ID1, ID2, ID3......
The Name column will be populated from a table that has the Name as well as number of ID's associated with that name. eg [Name1][3]
I need to display linkbuttons that link to user-id related documents in columns 2 to n for each name.How do I dynamically add linkbutton columns from code behind?
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 to create a customized Next/ Previos solution, the DataPager is not flexible enough for what I want. This is what I have so far.
1. A user does a search and 100 records are returned, I have 25 records per page and so get 4 page numbers -- this is already done on search.aspx
2. The user clicks their choice (let's say its 'Post 10') and is taken to that record on details.aspx -- pretty standard stuff.
What I now need is a Next /Previous links on the details page -- so if the user clicked Post 10, on the details page will be two links, Next linking to Post 11 and Previous linking to Post 09. (i'll actually be using the post title as the text in the links not simply Next/Previous) I'm unsure about how I should begin to struture this, should I be looking at creating Temp Tables in Sql Server and step through the records or can I access the dataset from the search page and step through that?
[Code]....
My question is: how can i create my own parameter based upon the QueryStringParameter?
Example:
[Code]....
I now called it QueryStringGuidParameter.
The purpose of this is: I'm not sending any querystring's via the aspx?querystring other thasn aspx?guid={guid identifier}.I hope my code below explains it al little bit.
[Code]....
A soon as a page Redirects f.i. with this example
[Code]....
Instead of calling Response.Redirect i call the Redirect i created. This transforms the querystring in a session with a guid and parameter. The Redirect only sends the guid in the querystring. and the receiving page picks up the guid and translates it back into a querystring.
Purpose is you have a secure way of dealing with info sending via querystrings. Lets say in the past you could easily get other info from the page by just changing a value in the key send via a querystring. In my case lets say the user request a Customer "A" with querystring ?ID=1.
Simple change the query in the addressbar to ?ID=2 (or something else) would give him another customer. Maybe a customer he is not allowed to see. (Of course this can be prevented also in the business layer, but that's not the point.)
So if i simply could create a new QueryStringParameter lets say called QueryStringGuidParameter which i can use in the ObjectDataSource but ideally just for all controllers which are able to use the QueryStringParameter , i don't have to go into code behind and set the SelectParameters in there.
I have an application as in the following,
[Code]....
The application works, but I would like to have 10 results per page. How easily can this be done? I don't want to use data view or grid view like most of the examples talk about, I would like to do this in the fashion that looks like what I have now, only not so many entries in a whole page.
I'm trying display data from a sqldatasource but I need to customize fonts, sizes and layouts. What would be the best way to do this. There's not much data only 8 rows and 3 cloums.
It's for a display screen that will show workers how much product they have produced.
I was looking at binding the data to lables and laying out the lables in a table but that process looks intense and streching my knowledge.
Is there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.

View 1 RepliesI'm trying to access and display certain data in my database using category ID's. I've added values to the links in a link list and I was to have the selected value as the one that determines the selection in the selection statement. For example, "SELECT [ID_key] AS ID_Key, [Title], [Source], [PublicationDate], [Url], [CatID] FROM [Newsarts] WHERE ([CatID] = Linklist1.SelectedValue)". I know Linklist1.SelectedValue doesn't work or it may work and I don't know how but I want to be able to use the value selected from the previous link. Is there a way?
Also, after all the data is displayed, I would like them to become links themselves. Basically, I want to choose a category, then choose an article in that category, and they hit the link to display the article's content.
I've created details masters before but can't remember what links the two together. When an item is selected with a master, such as a gridview, what is used to tell the details view which record to display? Is it the DataKeyNames property?
View 4 RepliesI have a repeater in my page as follows:
<asp:Repeater ID="RepeaterVacancies" runat="server">
<ItemTemplate>
<asp:TableCell CssClass="evenTd" runat="server">
<asp:HyperLink runat="server" NavigateUrl="Vacancies.aspx?VID=<%#DataBinder.Eval(Container.DataItem,'id')%>"
ID="Hyperlink1">
<%# Container.ItemIndex + 1 %>
</asp:HyperLink>
</asp:TableCell>
......
</ItemTemplate>
</asp:repeater>
when I loaded the page, the numbers come fine, but the links are not evaluated well: Instead of linking to Vacancies.aspx?VID=170 for example, the link comes this way: [URL]
If a session variable is set to a certain value, I would like to make a href link invisible.
