Gridview Linking To Detailsview On A Different Page?
Jan 7, 2010
Im fairly new to .net so apologise if this is a simple request!
I have a simple page with a GridView control getting data from a sql database.
I have added a hyperlink as below
<asp:HyperLinkField Text="Select" DataNavigateUrlFields="title_id" DataNavigateUrlFormatString="title.aspx?id={0}" />
On my title.aspx page, i have a detailsview control and i want to be able to retrieve information using the id from the gridview hyperlink.
I have two dropdowns menu in detailsview (Both one table) . I want to change items in the second dropdown when the user selects an item in the first dropdown.
What I did as following but it does not work :
Add an empty SelectedIndexChanged event on the first dropdown and then, bind the second to the first under Selectedvalue. Also, sat AutoPostBack="True" on first dropdown.
In ASP.net when we perform paging over Gridview or DetailsView than the Gridview fetch all rows from the Database each time.Suppose our Database contains 100 rows and we have configured Paging in Gridview with page size of 10 records per page.But whenever we click on the the pager control of gridview for any particular page no. then GridView should fetch only particular 10 row
I am trying to arrange the information from a SQL record into a 3 column by 3 row table to fit the form presentation that I want. I have placed on the page 3X3 table and then tried to place a detailsview in the first cell for the first picture called P1dv.
I have place a detailsview in the last cell that would control the paging of information called Controldv. I need to fiqure out how to link P1dv paging to Controldv page action. I am using visual web dev. 2005. I am not updating or editing these are read only views.
example of what i need the form output to look like:
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
I would like to wire a datalist with a gridview. The datalist will display an ID that when clicked/selected will expand/select the record in the gridview. I would also like the reverse, when a record is selected in the gridview the id in the datalist would show selected. Both the datalist and the gridview are in an update panel and both should have the same index number.
I am new to web page development so I want to ensure I am going down the right path with this new project. Currently, I am populating a mainGridView on my webpage with infomation from my MS SQL database. Two features I would like to add to this page is to be able to add filtering and hot linking/cell clicking events.
I was also planning on keeping the mainGridView dynamic, so that as a user clicks on a cell I could update the mainGridView with new information. Say all of Sammy Davis' movies. I am trying to do all of this inside of code and leave the aspx alone for the most part.
My plan was to embed textboxes into a secondary GridView to handle the filtering. The user could click on a button to filter the query set and the mainGridView would update based on the filter. Since the mainGridView is dynamic I need to have the filters to be dynamic as well.
This might sound like a stupid question, but here is what I want:in an aspx page in Sharepoint wiki, there's a section that I can insert rich text and html code. Here I want to transfer plain html pages to sharepoint wiki.The original html page has many in-page links, like "/Build_Environment/SQL/macs.html#CREATE_TABLE" where links to a section called "Create_Table" in the same page.How would this be done in aspx page? Is it something can be rewritten in html format so that in aspx page, the html section will also work as before?
I am currently working on a project which involves creating many web controls, some of these web controls have buttons and links which post to aspx pages. However these pages are likely to change and could again change in future. It would be nice if I could list the pages as names in a config file and the resolve page name and do a lookup so when they change I just change the config file rather than all the controls. Firstly is this possible and/or is there a better method? It would also be good if there was somekind of chaching method so we dont actually have to query the file everytime.
I'm trying to solve an issue in an elegant way. The problem at hand is I have 2 aspx pages (I'll call then Page1.aspx and Page2.aspx).
Page1.aspx contains an AJAX tab control with 3 tabs (I'll call the control Tab1). Page2.aspx also contains an AJAX control with 3 tabs (I'll call the control Tab2).
My question is, is there an elegant way to have a hyperlink on the second tab of the Tab1 control that links to the thrid tab on the Tab2 control? And, is there a way this linkage can be represented as a web address (example : http:\someserversomeappsomepage.aspx???TabControlIdentifier,???TabNumber.
The current methodology we are implementing is to pass the TabControlID and Tab number as querystring values and the set the focus in the codebehind of the page. But the only way I can think of to implement this across multiple pages is to have all the receiving pages implement the same overriding class that handles the focus issue.
I'm trying to link a detailview to a gridview. Both are using the same datasource control and it's coming from an Access database. Both are showing data. The gridview is listing products fine and the detailview is listing details of some default product (maybe the first). How can I configure the two so that when I hit my select button on my gridview that it populates the details into detailview with the correct data for the selected product?
I have an issue that I've spent quite a bit of time trying to solve. I have a Detailsview and a Gridview that I have linked using the ID field, It has now been decided that they want to have individual pages for each Unit. I have this working for the most part, however the detailsview is not being displayed until I hit select the row in the gridview.
How do I get this to automatically display on page load?
A few questions regarding detailsview and gridview:
1) when page load, how can I default the detailsview to show the first record from the gridview? SelectedIndex does not have any effect to my detailsview.
[Code]....
2) how can I select a record in the gridview if my table has 2 key fields using below syntax?
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?
I am creating a GridView/DetailsView page. I have a grid that displays a bunch of rows, when a row is selected it uses a DetailsView to allow for Insert/Update.
My question is what is the best way to link these? I do not want to reach out to the web service again, all the data i need is in the selected grid view row. I basically have 2 separate data sources that share the same "DataObjectTypeName", the first data source retrieves the data, and the other to do the CRUD.
What is the best way to transfer the Selected Grid View row to the Details View? Am I going to have to manualy handle the Insert/Update events and call the data source myself?
Is there no way to link these two so they use the same data source ?
In ASP.net when we perform paging over Gridview or DetailsView than the Gridview fetch all rows from the Database each time.
Suppose our Database contains 100 rows and we have configured Paging in Gridview with page size of 10 records per page.But whenever we click on the the pager control of gridview for any particular page no. then GridView should fetch only particular 10 rows from database.
If we click on page no 3 then it should query only rows 21-30 but it fetches all rows and neglect the remaining .which is simply a wastage of resources.
I'm hacking my way through ASP.Net WebForms, coming from VB.Net WinForms. I was hoping the transition would've been more seamless... it is not.
I have a GridView (Paging enabled) bound to a DataTable, filled with Joined tables from an Access 2000 DataBase.
The GridView and DetailsView are bound to the same DataTable.
In the GridView's SelectedIndexChanged Event I have the following:
vb.net Code:
' dtvSelected is the DetailsView' dgvJobTOF is the GridView Me.dtvSelected.PageIndex = Me.dgvJobTOF.SelectedIndex
When the page loads the first item in the GridView is also displayed in the DetailsView.
I've added a "Select" button in the GridView and when it is clicked the Data in the DetailsView remains the same regardless of the selected GridView row.
am in commercial development for few months only,the team leader is not using gridview, detailsview, formview, repeater, datalist.we alwyas write our own looping to dislpay the data even it is read only.He said : we do this for better performance.and I am always thinking, so why microsoft create them???I checked other questions and articles, and I am still confused.
I have a GridView and DetailsView in a Master/Detail relationship inside an Update Panel.The GridView displays a set of records, and when a Select button in the GridView is clicked, the detailsview displays the record for edit.Initially the focus is on the GridView, and when the Select button is clicked, I want the focus to be on the first TextBox inside the DetailsView. This happens only when I remove the UpdatePanel from the form. If the Gridview/Detailsview pair is inside an updatepanel, the focus never goes to the DetailsView.How can I make the focus on the DetailsView inside an UpdatePanel
I have 2 ddls (cascading that does not use the AJAX cascading ddl) within an updatepanel within an EditTemplate field in a DetailsView. Changing the first ddl causes a full page refresh (this is the problem I am trying to overcome), but changing the second ddl does not. The second ddl is set to autopostback as well because of other logic (if user selects value "Add" a modal pops up to add a new option to the database).
Now the first, does a call out to a class to handle setting the list of values for the second...that is the only difference I can tell between the two, but I wouldn't think that would cause the issue because it is within an updatepanel.
Here's the code:
[Code]....
On Selected Index Change code for each
For the First:
[Code]....
For the Second:
Protected Sub ddlModel_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim ddlModel As DropDownList = dtlBikes.FindControl("ddlModel") Dim ddlMfg As DropDownList = dtlBikes.FindControl("ddlMfg") If ddlModel.SelectedValue = "Add" Then 'Add New Record txtDDLName.Value = "ddlModel" txtDtlsViewName.Value = "dtlBikes" txtItemType.Value = "BikeModel" txtParentID.Value = ddlMfg.SelectedValue txtNewItem.Text = "" txtNewItem.Focus() lblNewItem.Text = "Enter New Model:" modInsertItem.Show() End If End Sub
I have a gridview and detailsview on the same page. The detailsview is defaultmode="insert" and works perfectly (Role, Site and Department are all bound to ddls). The gridview displays information fine and deletes fine - but when i click edit it breaks. But i dont understand why as it is using the methods and data sources as the gridview. I did a test run on this a few weeks back and it worked in visual web developer, lost all the data when i formatted the hdd and now - i cant get it to work, but i am sure its exactly the same. error is
DataBinding: 'System.Data.DataRowView' does not contain a property with the nameXXXX.
It does that on each of the ddls for site, role and department. But the property is there! i can see it when i test my SPROCS and they display / work fine in the detailsview.
We are using gridview to display data and detailsview to show details, update, insert, and delete as needed. I am a bit confused on whether or not htmlencode and htmldecode is needed when storing data from detailsview. Gridviews always use boundfields and I think encoding and decoding is built in. For detailsview we use mostly templatefields (eval(), bind()), some boundfields, and some data is stored in codebehind using e.values[] or e.newvalues[].Here is where I've got the idea:http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.detailsview.itemupdated.aspxIf I use the iteration and htmlencode, detailsview read only mode displays decoded data. However, gridview displays encoded data and of course update mode of detailsview. So, it seems like detailsview using htmlencode and htmldecode somewhat, but I am not clear as to what degree and what would be the best way to handle it.
I am designing a web page that allows for the maintenance of a single table - so I have some controls that allow the user to specify some search parameters, a button that then populates a gridview with the result of the search meeting the search parameters, and a details view for inserting and updating specific records. The gridview and detailsview are bound to appropriate sql data sources.All pretty standard.There is also a "reset" button that clears the results of the current search - sets the visibility of the gridview and detailsview to false, and clears the search parameters. Again, pretty standard.What I have done is when the user goes to insert a new record, the gridview and search parameter specification controls are hidden, and the details view displayed. If they cancel the insert operation, the details view is hidden, and the search parms and gridview displayed - but what I am finding is that there are situations when a previously populated gridview is displayed. Here's the situation:1) Specify some search parameters, click search - and the gridview appears, with the appropriate records displayed.
2) Click on the clear button (oops - I didn't want to search, but add a new record). The gridview disappears, the search values are cleared out.3) Click on the insert button - the detailsview opens in "insert" mode.So far, this all works well, and is intuitave to the users.4) Click on the "cancel" button on the details view. I hide the details view, and show the gridview and search parameters. The gridview appears - with the results of the previous databinding still in it.My question is: Is there an easy way to "unbind" the gridview? From my understanding of how the datasource to gridview (or detailsview) connection is done, there is a datatable "behind the scenes" that manages the two way data binding. I also assume that data that has been bound to a gridview is carried over in the viewstate - it would be nice to clear out unneeded data in that.
