Dynamically add options select using javascript
Here is the skeleton of class DynamicallyTemplatedGridViewHandler implementing ITemplate with a list of data members and methods. ItemType keeps the type of a list item type: Item, EditItem, Header, Footer, AlternatingItem, Pager, SelecetdItem or Separator. In this demo version we need only three of these; we need Header For heading of each columnItem for showing fields when GridView will be in normal mode and EditItem for showing fields when GridView will be in Edit mode. FieldName keeps the name of each template field that will be displayed in the header.
InfoType keeps an indicator in string form for a type of information within a template field i. A "Command" Edit, Delete, and Insert requires instantiation in the Button control while he "String" requires a Label or TextBox.
Now, coming to the member methods listed above, there is a constructer which simply sets the aforementioned data members with those passed as parameters. Here is the explanation of InstantiateIn the only method of ITemplate being implemented by our class DynamicallyTemplatedGridViewHandler. InstantiateIn ensures that the list item type of each template is created in its appropriate control. For better understanding of functionality of this method see its name "InstantiateIn. Like in the case of a Header, it is instantiated in Literal control as shown in this part of the implementation of InstantiateIn.
InstantiateIn takes a "Container," a Control type object as a parameter. Container's control collection is filled with all controls in which items of each type are instantiated. Finally, add this control to the control collection of the Container control passed as parameter to InstantiateIn method. Similarly, we have to write instantiation code for ItemType if it is "Item" and "EditItem.
If InfoType is a Button then it creates three buttons for the aforementioned tasks. It is simple to do; create a button object, set its all properties accordingly, also add the button's click event handler and finally, add it into the control collection of the control Container passed as an argument.
When InfoType is not a Command it means we have to instantiate it with a label as in GridView's normal mode when each cell text of GridView's rows is displayed in label. Therefore, by default, control is instantiated with Label and is added into the Container.
Since we have no more info types other than command and string then no further checks are required. We come to the outer check when ItemType is EditItem. Now, we need an inner check for info type command or string. The template field will be instantiated in Button if the info type is Command; otherwise it requires TextBox for the cell text of edit item. If the these text boxes are emptied, they can be used for insertion instead of editing without dedicating an extra row for it.
This is easy and handy as it becomes a better approach when it is not known in advance how many columns there are in GridView's data source. I have taken a session variable InsertFlag that is set to 0 and 1 for Edit and Inert operations respectively. Since we have to bind the labels in Item template and text boxes in EditItem template with corresponding cell values, the data binding event handler OnDataBinding of both label and text box populates the fields with cell values accordingly.
And you might also want to know how text boxes for each field get emptied when Insert button is clicked. The solution is simple; do not bind them with a database and apply a check while adding the data binding event handler of text box. Do not call OnDataBinding if the insert button is clicked. The implementation of the data binding event handler "OnDataBindin"' is simple. They do nothing except the former sets the Session[InsertFlag] to 1 and the later sets it to 0.
Hi Mohyudhin, Actually i tested this for my scenario and its not working when i try to add the grid control itself from code behind instead of declaring it in DOM HTML. In that case the edit item template update and cancel button events are not firing. Anybody faced similar issue? Hey Bro, Hope you are doing good. Thanks very very much Bro. Nicely explained and clean code dude. Can you please help with many have asked also having a dropdown in the column.

The GridView control raises the Sorting event when a Sort button a button with its CommandName property set to "Sort" is clicked, but before the GridView control handles the sort operation.
This allows you to provide an event-handling method that performs a custom routine, such as canceling the sorting operation, whenever this event occurs. So change the header by LinButton and then implement the GridView sorting method. How to implement the Sorting, Please help I figure out by myself. In short, the literal does not make the HeaderText clickable, so it needs to use linkbutton instead inside the handler class.
In addition, inside the class, it also need to add a event handler for linkbutton click from where you can call gridview sorting function directly. Thank you for your great article. I'm trying to make the header clickable in order to do sorting on each column, but failed. Hi, You need to implement optimistic concurrency in your application to get rid of this problem in multi user environment.
For this you need to keep a version field in the table being bound to the grid. It should be 0 by default when record is inserted. When you load in edit mode keep the version in viewstate or session or in some hidden field. Whenever it is refreshed or re-loaded match its new version with the one saved in session. Hi, This article was very helpful.
However, it would not work in multi-user environment. Say for instance, User A and B load the same page. User B deletes row 5 while User A is still viewing the old data. Then User A clicks row 7 for editing. Can you suggest a workaround for this scenario? DataSource as DataTable; if dataTable! So no decision can be taken to on that time. If you are following my implementation you can try i m not sure to call InstatitateIn method once again after databinding and may add check here in following case adding the button for edit, and the key value can be set in some session vaiable.
Hi, Whenever a button is created in GridView and u want the fields info of the particular row in which it has been clicked, u must handle RowCommand event of the GridView. This allows you to provide an event-handling method that performs a custom routine whenever this event occurs.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event. The OnRowCommand method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class. Hello, can you help me? I read your article about gridview, it's very good and I'm using in my application. I created one button in gridview to show details in another page.

Could you help me to overcome the problem. It would be a greathelp for me It is possible to achieve that you need.
What you have to do is add a 'case. When it will be claled implitely by the GridViewHandler contructor will add a GridView in ItemTemplate of the column instead of buttontextbox or label etc. In CreateGridView method add TemplateField as already one has been added for Buttons set its item,edititem and headertemplate through the gridviewhandler class contructor.
I hope it will work. How could you set up something so that cells that are foriegn keys would give you a gridview of the table that it is referencing which you could then select an item to populate that cell?

Sure you can do it in code. But make sure your all fields require it or add a condition based on the id of the field.
Add rfv ; Hope it works. The default behaviour of GridView is that there must be at least one row in table to make table displayable. You have noticed that Insert option like Edit and Delete is in each row.
And even if i provide Insert button globally, there must have been at least one empty row to be filled i. There are workarounds for it but they deviate from the core intention of the solution.
You may add a fake row in table and do all insertion from GridView and later delete that row. Is this possible to validate text box fields while inserting or updating for example date field Title: When am opening a table which doesnt have any values. Although updating multiple rows depends upon the WHERE clause in GenerateUpdateQuery method but the GridView control enters into edit mode only for single row.

Text; I always get error: Object reference not set to an instance of an object. Although I could not incorporate an IBindableTemplate example in this article as the the title is not primarily meant for that yet I have changed the current solution for ITemplate.
ITemplate can provide the required features under the current title. I am thankful to you for suggesting it, I have removed all references of IBindableTemplate and have used ITemplate. Looks like gridview just won't support sorting a templated column. I changed the CreateTemplatedGridView code to use a BoundField for one of the columns instead of a TemplateField and sort became active for the column. I created a readonly version of your sample code and here is where I'm adding the sortexpression property.
Maybe this is not the right place because the column headings are created as literals instead of linkbuttons. Yes it should support but you need to set SortExpression property of particular field in code and write event handler of OnSorting event of the GridView.
Can it be done? Would you please send me the error description Title: Text;'' u convert in vb form and in vb. Text '' but i have occured error so u help me in form of send me solution on my mail id. Actually it has been left upto user to decide which column of the table, he decides to be the primary key field.
