I am working in asp.net 3.5 page, where I want to bind a textbox with generic list data. And I have Previous & next button. Which will show the record in textbox.
I don't want to go in db again and again.
I am trying to bind the gererist list type to GridView control but for some reason its just displaying "Member"(Object name) rather then the actuakl content inside object.Any Idea why?Below i have decleared a List Type Member:

And the Below trying to bind with gridview:

i tried reading all the articles and tried the solutions as well did not work for me.
One of the solutions i tried
Binding Generic List Array to GridView.
The new project file that I created using your tweeked sample code is below:
[code]....
I have a generic List which is populated with an object which has properties like FirstName, Surname etc.
If I bind a gridview to the list with autocompletecolumns = true, the Gridview displays the data in the List.
The code looks like:
[code]....
My question is:
How do I populate the DataKeyNames with the properties (FirstName, Surname) contained in the object that is contained in each element of the Generic List?
I've had a bit of a problem trying to bind a generic list to a repeater. The type used in the generic list is actually a struct.
I've built a basic example below:
[code]....
I then create two fruits using the struct (apple and orange). These fruits are then added to the list.
Finally, I bind the generic list to the DataSource property of the repeater...
The markup looks like this:
[code]....
I expect to see the fruit name and price printed on the screen, separated by a horizontal rule.
At the moment I am getting an error relating to actual binding...
**Exception Details: System.Web.HttpException: DataBinding: '_Default+Fruit' does not contain a property with the name 'FruitName'.**

Getting records From DataBase using DataTale which contain 1000 Rows, then binding to GridView using Generic List. Like above Example

Now i want to do search, sorting & Paging in the GridView with out Postback of the Page & with out hitting the DataBase when do Paging or searching in GridView.
I have the following Students class:

I need the 1 since it's a foreign key in another table. For the life of me, I can't get this to work like this.
I have a few web applications that I maintain and I find myself very often writing the same block of code over and over again to bind a GridView to a data source. I'm trying to create a Generic method to handle data binding but I'm having trouble getting it to work with Repeaters and DataLists.
Here is the Generic method I have so far:
[code]....
That way I can just define my CommandText then make a call to "BindControls(myGridView, cmd)" instead of retyping this same basic block of code every time I need to bind a grid.
The problem is, this doesn't work with Repeaters or DataLists. Each of these controls inherit their respective "DataSource" and "DataBind" methods from different classes. Someone on another forum that I implement an interface, but I'm not sure how to make that work either.
The GridView, Datalist and Repeater get their respective "DataBind" methods from BaseDataBoundControl, BaseDataList, and Repeater classes. How would I go about creating a single interface to tie them all together? Or am I better off just using 3 overloads for this method?
I have GridView bound to some List. In layout I created following template field:
<asp:TemplateField HeaderText="Phrase">
<ItemTemplate>
<asp:TextBox ID="phraseTextBox" runat="server" Text='<%# Bind("Phrase") %>'/>
</ItemTemplate>
</asp:TemplateField>
But after changing the content of any TextBox in column "Phrase" my List doesn't reflect that changes.
I have a list view control. Each row within it has a rowid and a textbox where a note(user enters relevant info to that particular record) is entered. On a paging event I store the rowID and the note text in a generic list for retrieval if the user pages back later on. Goal here is to keep the text the user has entered. (see the code below)This generic list does in fact get populated correctly when I go to the next page currently. I can see this in Visual Studio. So now, when the user goes back to the first page I want to run a test within my Listviews ItemDataBound event. I want to see if the row ID being tested is part of the generic list. If so, I then want to take the corresponding note that is also within the list and bind it to the text box. However, I don't know how to write the correct conditional for this and how to bind the textbox if the conditional evaluates to true.

imagesToRender.Add(imageThing1);
imagesToRender.Add(imageThing2);
Repeater1.DataSource = imagesToRender;
Repeater1.DataBind();
}

View 7 RepliesI have a generic list which contains a class called Parameter. Parameter contains 2 integers, ParamType and ParamValue. A generic list is built containing a small number of values List<Parameter> myList I have created a function which passes in 2 parameters. These are passed individually but are used to create a new Parameter within the function. The Parameter is tested against myList, and if it is found removed. In order to do this I have used the remove function, the syntax being:
myList.Remove(new Parameter(ParamType, ParamValue));
The remove isn't working and at present I'm using LINQ to do it.
