From Google i figured out these can be used to bind the columns in GridView to ArrayList. But what is "some property" ?For example i have a ArrayList in .aspx.cs as
static ArrayList componentSelectionArray = new ArrayList();
so can i just write in grid view to bind a arraylist to grid view columns as:
I am using subsonic in asp.net forms C# and I have an instance where I need to loop through a recordset and for each one call the Database to get specific information from a view about that record.
in this instance it is a venue, loop through and for each venue I show there spend and there budget, but I am at a loss as to how I can say use a gridview, execute more code on each row and then add more columns to that row.
just as an update i have been playing with the idea of something like this:
DataSet ds = new DataSet(); ds.Tables.Add(LinqToDataTable(club.All().Where(x => x.level == 1))); ds.Tables.Add(LinqToDataTable(ViewBudgetSpend.All().Where(x => x.periodfrom == curperiod))); DataRelation relation = new DataRelation("budgets",ds.Tables[0].Columns["clubId"],ds.Tables[1].Columns["clubid"]); ds.Relations.Add(relation); still working this out though.
I am trying to set come columns to invisible after all of the rows are binded but I'm having trouble. I'm hiding columns that have empty data which I save in a session variable. This works fine. Then I tried changing the columns visible property using the ColumnByName routine in the DataBound but that must be the wrong event because I do not think the columns exist yet.
The columns are autogenerated btw.
Where can I set the columns properties after it has binded? Can i do this before the columns are autogenerated the the screen itself?
I want to know the procedure of binding a gridview. but the condition is that thefre are three columns in this gridview. if I wud bind it from one table then it wud ok for me. but now I need to bind it from three different tables. onw column from one table, another from 2nd.. and so on.
We know that using something like Bind("CustomerName") can be used in the Text property of a label control inside a gridview, where CustomerName is a property of the object whose collection is bound to the gridview. If that property is of a complex type (object of another class), how do we use a property of that inline object as a binding for the gridview column?
I'm looking for the best way (Performance) to do gridview columns formating RunTime /Dynamic depending on the datatable Columns type ,I want to bind the datatable to a gridview and format the Date columns to short date, and currency columns formatted with comma ex 10,000.00 inplace 100000.00 at datatable the column type is double run time (without converting them to String) since I do a filtering and sorting at these columns.
In a nested GridView (GridView inside a template column of parent GridView). I am binding child GridView to a DataTable in parent GridView's RowDataBound event. this works as it should. But the problem i am facing is in Child GridView's RowDataBound Event, when i try to access e.Row.DataItem property it returns null. I am expecting it to return DataRowView Type. which i will then use to set values of TextBox's.
I have a button inside my <ItemTemplate> in GridView and I want to call a javascript function on the OnClientClick of that button passing the DataItem value as a parameter of the javascript function
[code]....
If I will not put a parameter in CreateEditAddess() this works well but I need the parameter.
I know I can put the OnClientClick event value in OnRowDataBound event of the gridview but I don't want to put it in CodeBehind. It seems like the server tag is not parsed correctly.
I'm using the GetOleDbSchemaTable to get column info from an access db, column_name and description, but getting an error that the bind statement can't get the properties. I know its there because I can response.write it from its table, schemaTable.Rows(i)!DESCRIPTION.ToStringdo I have to bind it differently than when binding actual data from a table using the column name for reference?System.Web.HttpException: DataBinding: 'System.Data.Common.DataRecordInternal' does not contain a property with the name 'DESCRIPTION'.
I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns() { // The first column to begin to insert the columns in the GridView int columnIndex = 5; BoundField aoColumn = new BoundField(); aoColumn.HeaderText = "New Column 1"; gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback gvMyGrid.Columns.Add(aoColumn); // works fine columnIndex++; foreach (MyEntity my in _myEntityCollection) { BoundField myColumn = new BoundField(); myColumn.HeaderText = String.Format("{0:d}", my.StartDate); gvMyGrid.Columns.Insert(columnIndex, myColumn); columnIndex++; } }
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.
in asp.net page user able to select gridview Columns, and it will hide remaining columns and that selection done by check box with column list bellow is Image link , what exactly I am looking for [URL] it look bellow after selection of column done [URL]
I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
I apologize for the odd title. I've been trying to figure out how to do this and can't quite put it into words. Basically, I need to try to display a GridView with a whole bunch of columns (37 in one case) in two "rows" of columns. More or less.
So instead of this:
Column1 Column2 Column3 Column4 Column5 Column6 Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data
I'd like something like this:
Column1 Column2 Column3 Data Data Data Data Data Data Data Data Data
Column4 Column5 Column6 Data Data Data Data Data Data Data Data Data
As in the example there can be multiple rows returned which all need to be displayed. I'm trying to stop a very large horizontal scroll bar being required. I've been searching as much as I can but haven't found anything that fits what I'm looking for.
I'm binding a gridview from a webservice with 30 columns and 10 rows, I need to print the same in a PORTRAIT, for that i decided to display columns as rows and
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 use this bit of code in the code behind a OnRowDataBound comand of a gridview:
Code: (int)DataBinder.Eval(e.Row.DataItem, "SectorID")I have made some changes to my Class so that SectorID is now a list of ints. How do i return the first item in the list using the above method?
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.
