I am trying to make a simple grid view that is binded to a simple xml document but I must be missing something since I am keep getting error message:
The data source for GridView with i 'GridView1' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.
im reading checkbox value which is checked on my gridview but as per my code is missing the 1st one which on top but i select from the middle then it is working fine here is link for gridviewhelper classes [URL] and im calling this code from gridviewhelper classes on page load event
Dim helper As New GridViewHelper(Me.GridView2) helper.RegisterGroup("heading", True, True) AddHandler helper.GroupHeader, AddressOf helper_GroupHeader
and here is my code
Dim sc As New StringCollection() Dim id As String = String.Empty For i As Integer = 0 To GridView2.Rows.Count - 1 'loop the GridView Rows Dim cb As CheckBox = DirectCast(GridView2.Rows(i).Cells(2).FindControl("CheckBox2"), CheckBox) 'find the CheckBox If cb IsNot Nothing Then If cb.Checked Then id = GridView2.Rows(i).Cells(1).Text sc.Add(id) MsgBox(id) End If End If Next
I am trying to add an additional column on the gridview. Everything work fine. The problem is, when i add a new button on the page where the gridview exists and hit the button. The added column in gridview went missing. The button do not have any code behind associated with it and I am using VS2008. Anyone know what have cause this and how to solve this problem? I need the added column to be there even user click on the button.
I've coded a GridView in the markup in a page. I have coded a DataTable in the code-behind that takes data from a collection of custom objects. I then bind that DataTable to the GridView. (Specific problem mentioned a couple code-snippets below.)
Goal: I'm basically trying to find a way to update the data in my GridView (and more importantly my cart Session object) without having to do everything else I've seen online such as utilizing OnRowUpdate, etc. Could someone please tell me why gvCart.Rows is empty and/or how I could accomplish my goal without utilizing OnRowUpdate, etc.? When I execute this code, the GridView gets populated but for some reason I can't access any of its rows in the code-behind.
I have a Gridview which is populated from an ObjectDataSource. Data Source has a control parameter hooked up to the SelectedDataKey value of the GridView. My Gridview has rows which may not have a DataKey. I am receiving an error when a GridView row without a DataKey is selected.
I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
I am using gridview. I Added checkboc under itemtemplate.My page works fine. i have set my page according 508 standards. It looks for associated control id for every textbox, check box..etc.
When i check my page by 508 standards its giving form lable is missing for gridview item tamplate checkbox. i tried adding lable inside item tamplate and i set the check box id as Associated control id for the label. eventhough its not going off that error. After setting some text my errors are resolved.
but if add any text item template checkbox alignment is missing. i cann't hidden the lable. If i hidden the label it again show up Form label is missing. how can i add lable without effecting to GV item template checkbox alignment.
I have a XML file which contains a list of items/elements:
[Code]...
I can bind the data into a gridview. However, only the attributes are displayed(which is: category and ID). I need the elements to display out too (which is: Name,Description,Latitude and Longtitude).
Would anyone be kind enough to solve this problem for me?
And is it possible to populate a drop down list in using the same XML file? As in populating the category in the drop down list.
I have an arraylist of string items that I want to bind to a gridview.I want to bind the value from each item to a asp:HyperLinkField but I dont know what the DataTextField should be? The arraylist obviously doesn't have a column heading as it's just 1 dimensional.What value do I need to use in the DataTextField?
This a pretty simple question, I'm just not sure how to do it exactly. I would like to bind a Button or perhaps ImageButton to a GridView in ASP.NET/C#. Currently, the GridView has two columns and is bound to a DataTable with two columns. I want to add a third column to the GridView, which will include the Button.I know GridView has ButtonField, but I'm not too sure how to go about using it to do what I want. I want to dynamically generate these Buttons and add them to the GridView.Here is how my GridView looks right now:
I want to be able to click on a cell in the GridView and determine the data in the cell. So using the example from here [URL] .... I created a new class inheriting the GridView class. But the problem I am running into now is that the data is now being added twice to the GridView so that I have twice as many columns than I had before. Base on what I was able to gleem from the Internet is that the DataBind method is running twice. Once for my class and once for the inherited class.
What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
I am using the ajax control toolkit - Tabcontainer. I wonder how to refresh the latest data inside the tab. For example, I have two tab. The first tab is a add form. After I add the form, I prompt out a successful message. Then I click on the second tab which is my gridview listing of the inserted record. But when I click on the second tab, it seem not binding the gridview to show the most latest record I have inserted.
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.
how one might go about binding to a gridview in ASP.Net 4 in a scenario where the first row of my gridview should be the headers, the second should be a combobox for each column and the third is the beginning of my actual datasource.
If you can imagine what I am trying to achieve is an ability to create a binding between each column in the datagrid and another datasource. This binding is created by the user selecting a value in the comboboxes. However no matter what I try I cant seem to achieve this.
Is their any way I can bind each column of the grid seperatly with each property? It is possible to do that in web form, but i am not sure about MVC grids.
I want to bind gridview at runtime on button click.
I have use AJAX toolkit control, it's reference on that page(also script manager and update panel controls required for AJAX controls). When i remove all these from my page gridview data binds successfully. But when i use these controls and AJAX library reference, data is not binding to grdiview control. But at debug time it shows row count to 2 which is exact count which i wants.
here is my binding sample.
AMCGrid.DataSourceID = "AMCFILLAll" AMCGrid.DataBind() here AMCFILLAll is my sqlDatasource.
I am developing a web application where in i have a WCF service which interacts with the database using entity framework. I want to get rid of creating Classes for each & every LINQ query e.g
public class Emp { public int CD{get;set;} public string Name{get;set;} } public List<Emp> GetServTypeForPromotionDue() { return (from a in Context.TableName select new Emp{ a.CD, a.NAME }); }
for other table & LINQ i have to create a separate class every time. Alternative to this is to use Anonymous method which is not preferable solution. To avoid both the methods I am using Tuple Class where I return List> or List> depending on the return type. This works fine but the problem is I am binding the result of LINQ query directly to a Gridview By default Tuple has properties item1,item2,..& so on. So my griview shows these names are column names so, Is there any way I can change the property name to CD, Name instead of Tuple's Item1, Item2 before binding to grid?
i m binding data to Gridview using LinQ i need to sort the Gridview i have no idea how to sort cs i m using LinQ to Bind data with Gridview at Button Click.
I am working on a VS 2005 based Environment, on .NET 2.0.am trying to Bind a ArrayList to a GridView. The ArrayList consists of Objects of a Specific Class. When i bind it now all the Properties in the class. The catch is I do not want to display all these properties on the GridView.For Example: The objects of this class is held in ArrayList, when i Bind it to GridView it shows all the four Columns, Where as i want to show only 2...
