I've a gridview bound to linqdatasource1 and a details bound to linqdatasource2 (for searching).
When I update the data on detailsview, my gridview is not updating. I've tried handling various gridview events and databinding the gridview in code but it doesn't seem to work.
How I can bind texbox to one property from linqdatasource?
I mean something like databinding contols in c# app
Im making a Master details web page ASP.NET. I have one aspx page with all the items in a listview, then a link to another page to show the details view, but I dont want to use a asp:detailsview control becasue it generates a table, and I want a more complex layout. I want work each property of the item, but I dont know how. I want to do in LINQ. This is my very bad aprox: I need an orientation of how to get ONLY one item from the LinqDataSource on the page load and not to query the database everytime I need a column. I dont need biding because I only need to show data, not insert, not update, not delete...
View 2 RepliesI have an image in a particular View that an authorized user can replace with an uploaded image. Once the upload is started, a form POST action rolls in a Controller method named Upload (very clever on that part). After the image is successfully saved (to the same source location as the image source in the View), a RedirectToAction is called to re-render the View.Everything works, except that the old image is still displayed. If I reload the View, the new image shows correctly. Since I called RedirectToAction and ran the Controller method to return that View after the file was saved, I expected to have the changes shown without a manual browswer refresh. Why is this occurring?

I have a LinqDataSource and a GridView displaying a table. Columns of type xml don't show up. I'd like them to show up something like they do in Sql Server query outputs, with a link to display the clickable xml, though there may be another approach i'm not considering (maybe a styled display of the xml data, etc.). Two things i'd like to know how to do
First, get the xml converted to a string, and display it in the table. Maybe the first 30 chars.
Finally, style the xml into something useful, like a clickable link to display the full xml, or a sub-table, or a styled string.
So the following works, and displays a nice table, with edit and delete links. But Xml fields are missing. How would you go about adding support for the Xml fields?

i have a grdidview control on the .aspx page and i am trying to connect dynamically from code behind and bind the gridview but somehow it throwing me an error... what is wrong with this code?
LinqDataSource LDS_POReport = new LinqDataSource();
LDS_POReport.ContextTypeName = "DataContextDataContext";
LDS_POReport.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDataSourcePO_Selecting);
this.gvReport.DataSource = "LDS_POReport";
//this.gvReport.DataBind();
Update:
after i update the code to this.gvReport.DataSource = LDS_POReport;
it works fine but when i try to sort i get this error:
The GridView 'gvReport' fired event Sorting which wasn't handled.
i added this but no effect.
LDS_POReport.AutoPage = true;
LDS_POReport.AutoSort = true;
the problem is not solved the way i wanted but i go ahead give the credit to : ŁukaszW.pl for his time and effort.
i am using gridview control and a linqdatasource and its all working fine and i have added the functionlity of searchingBySubject and i added WhereParameters and than binding my gridview (see the code below) but somehow its not returning any rows and i see i have number of rows based on what i am searching.
protected void btnSearch_Click(object sender, EventArgs e)
{
this.LinqDataSource1.WhereParameters["Subject"].DefaultValue = this.txtSubject.Text;

I have two tables:
Orders
OrderProducts - An order can have 1 to many orderProducts records associated with it.
What I am trying to do (unsuccessfully) is to implement a GridView search using a LinqDataSource wherein the search returns Order results where any of the OrderProduct.Manufacturer columns contain a search query. I was hoping the following would work, however it seems lambda expressions do not work within a Where clause of a LinqDataSource (in VB):
<asp:LinqDataSource ID="dsOrders" runat="server" ContextTypeName="myDataContext" TableName="orders"
Where="orderProducts.Any(Function(op) op.Manufacturer.Contains(@searchTerm))">
<WhereParameters>
<asp:ControlParameter Name="searchTerm" ControlID="txtSearchTerm" DefaultValue="" />
</WhereParameters>
</asp:LinqDataSource>
In C# it would look like:
<asp:LinqDataSource ID="dsOrders" runat="server" ContextTypeName="myDataContext" TableName="orders"
Where="orderProducts.Any(op => op.Manufacturer.Contains(@searchTerm))">
<WhereParameters>
<asp:ControlParameter Name="searchTerm" ControlID="txtSearchTerm" DefaultValue="" />
</WhereParameters>
</asp:LinqDataSource>
The error I am getting is:
No property or field 'op' exists in type 'orderProduct' Any clues as to how to get this working within the LinqDataSource definition, or will I have to handle and set up a custom OnSelecting event?
Im using a LINQDataSource to populate a GridView of Universities.
Each University has an associated State, which is in another table and associated by a foreign key (StateID).
I have a TemplateField in the GridView so that when you view it normally it displays the StateName which comes from the State table and when you edit it shows a DDL populated with everything from the State table.
[Code]....
If I debug, inside of RowUpdating, GridViewUpdateEventArgs.NewValues doesnt even have a key for State.
Question: How do I let my gridview know I want it to update this column? All the BoundFields just seem to work...
AllowSorting="True" AutoGenerateColumns="False" DataSourceID="LinqDataSource1">
SortExpression="UserName" />
SortExpression="FullName" />
SortExpression="Email" />
SortExpression="LastLoginDate" DataFormatString="{0:dd MMMM yyyy}"/>
<asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="MyDataContextDataContext" onselecting="LinqDataSource_Selecting">
<WhereParameters>
<asp:Parameter Name="Subject" />
</WhereParameters>
</asp:LinqDataSource>
public void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
this.LinqDataSource1.WhereParameters["Subject"].DefaultValue = this.txtSubject.Text;
e.Result = reporterRepo.GetInquiries();
I have three tables in database:
ARTICLE with fields like ID_Article, Title, etc. and also a FK ID_Author
CATEGORY with fields ID_Category, Name
CATEGORYTOARTICLE with fields ID_Article, ID_Category
Now I have a page that shows all Articles of a given Category. Inside there is a GridView.
[Code]....
The ID of the viewed Category is passed via QueryString.
How to access the fields of Article table so that I can create columns for them in GridView? I tried using Eval("Article.Title") but it keeps saying that "DataBinding: 'konserwatyzm.db.CategoryToArticle' does not contain a property with the name 'Article'."
The datasource of the datagrid is a LINQDataSource which relies on the value of a dropdownlist. In addition, I want to use the footer to insert new records - so I'd prefer not to use the empty dataset template. I am trying to find a way to always display the footer regardless if the datasource is empty or not.
EDIT:
Is there a way to create an empty/invisible object of the type in the LinqDataSource?

i am using gridview control and a linqdatasource and its all working fine and i have added the functionlity of searchingBySubject and i added WhereParameters and than binding my gridview (see the code below) but somehow its not returning any rows and i see i have number of rows based on what i am searching.
I'm using a GridView and a LinQDataSource (Northwind database) and this error appears when website runs.
Here is my codes on aspx file and no codes in cs file.

I have a gridview inside an updatepanel.After updating the gridview, accessing the individual rows does not seem to give the right row. For example:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow row = ((e.CommandSource as Control).NamingContainer as GridViewRow);
Row from the above code gives the values from the gridview before the gridview is refreshed/updated.
Here is the setup:
VS 2008Update PanelIn the update panel, is a gridview, and an asp:panel that contains some other controls, including the button I want to trigger the update of the gridviewThe gridview is tied to a sqldatasource, although I have tried multiple methods to get the data and all failed
Here is the problem:
User logs in and fills out the top part of the form. That submits some data to a table, returns the ID of the row submitted and makes an asp:panel visible (panel.visible=true). This update panel exists inside of the UpdatePanel. The user clicks a drop down list and selects a name. When this happens, another panel becomes visible, using the same process, to allow the user to enter data about the name they selected. So far, everything works.
What Should Happen next:
User clicks "Add" buttonDatabase is updated with the data enteredDatasource refreshesGridview refreshes - It is not visible at load because there are no records for it to show.
What Actually Happens:
User clicks "Add" button Database is updated with the data entered - This has been verified Datasource should update, but not sure it is Gridview does not show.
Here is the code snippet for the Update Panel:

I have bounded Gridview through Wizard. It's working fine. but i want that if i add new data it should be visible in the gridview. But gridview not refreshing. I know i can perform this programmatically . but i want to do it in this case also.
View 1 RepliesI'm developing a web application in ASP.NET 2.0 using C#. In this application in one of the pages i have a grid view which is populated from database on click ofa search button in that page.
On double clicking on any of the rows of the gridview, the particular row's details are populated in to new page. If the user modifies any details and saves i have to redirect to the previous page (i.e.. the page with the gridview). I used history.back(), the page gets redirected but the changes are not being updated in the grid as that doesn't get refreshed.
I have a Gridview within an UpdatePanel that shows some data from my Database. When you click on an edit button, it opens up a detailsView within a ModalPopupextender. When you enter in data in the textBoxes in this detailView and click "update", the Database is updated but the popup does not hide. Then, when I close it manually by clicking "close", the gridView does not refresh unless I refresh the page. I was able to get this to work before, but after spending a week staring at this problem.

I have a very strange problem here I am using a GridView which shows nothing the the page loads for the first time. But when user selects something from the dropdown above, it DataBind()s against whatever is returned by the stored procedure.
If ran the code in debug mode, it showed that gvMyGrid.Datasource had data in the list returned by SP.Then I did gvMyGrid.DataBind(), it keeps the same empty view.I tried one more thing, I bound the grid when the page loads for the first time to one of the default values returned. It showed the data but when I changed the dropdown selection, it kept the same data.
I have a problem when the databound gridview is not getting refreshed by the trigger that set to the dropdown outside the update panel. Both controls on ascx control that resides on the tabpanel within aspx page. I realise that both need to be in the same contianer, but because it's an ascx, I can't use Content (but it's used on the aspx main page. How to trigger the refresh of the grid?Here's the simplified code:
//Main Page - aspx
<asp:Content
ID="Content1"

To start I am using a MultiView control to step users through searching. The first page in the MultiView is just a search box with a button to preform the search.
The second page has the GridView, but I would like to keep the search box and button for the user to search again if they didn't find the user they were looking for.
When you search from page one and move to page 2 the GridView shows the correct results. But when it is on the second page with both the GridView and the search the GridView doesn't update. Below is the code I'm using.
