Getting records From DataBase using DataTale which contain 1000 Rows, then binding to GridView using Generic List. Like above Example
GridView1.DataSource= GetData();
GridView1.Binding();
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 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:

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 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'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'.**
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 problem i just cant get around...I'm trying to sort the contents of a gridview that gets filled from a List<T>.
(working in DAL, BLL & Presentation layers).
The Gridview's source code:

What i cant figure out is how to implement the sort method to the gridview when fetching data from a generic list... I have been Googling my a** of trying to solve this.
I have a generic list of a custom type. The custom type has a string and double.I'm binding the list to a gridview and it outputs everything fine.I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.
The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

View 1 RepliesI have the following Students class:
[Code]....
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 class with all different kinds of data members, including a list of strings. When I bind the data to a GridView, I want to be able to separate out the list of strings into different columns in the GridView. These strings are more like flags, there is a max of 3 flags. The list could be empty, if no flags apply, or it could contain only one or two flags. How can I separate out these flags into different GridView columns? Do I need to do it in the OnRowDataBound event?
Current, my aspx code looks something like this. I want to be able to change the ImageUrl of the Image controls based on if the flag is raised or not.
<asp:TemplateField HeaderText="Tax" SortExpression="Tax"> [code]....
I have a List<string> that I want to use as a datasource for the gridview, making the column a HyperlinkField type and passing the value clicked in the column in the url. My code:
private void DoBind(GridView grid, List<string> Accounts)
{
Hyperlinkfield field = new HyperlinkField();
field.DataNavigateUrlFields = Accounts.ToArray();
field.DataNavigateUrlFormatString = _urlToRedirectFromGrid;
field.DataSource = Accounts;
grid.Columns.Add(field);
grid.AutoGenerateColumns = false;
grid.DataBind();
}
I can't get this to work. The page throws an AJAX null exception when this method is called.
I need to bind a List control based on the Gridview Row's datakeyName value while the Gridview control is being loaded into the page. I tried the following but it does not work.The BulletedList control is nested inside a Gridview Control and they both bound to an ObjectDataSource control. In my code, I passed teh UserID into the UserID parameter and call the Select() method but still does not work. Basically, I want to list of a user's hobbies, therefore the hobbies control are driven by the userID. tell me how can I get it to work?

I have a Gridview that displays paged results from a search query. The problem I am having is that the gridview is not displaying all the results returned from the query. For example, I can step through the code and see 6 items returned by the call to GetList(), but only 2 rows get rendered by the gridview after binding.
I am using an ObjectDataSource created in code:
ObjectDataSource ods = new ObjectDataSource();
ods.EnablePaging = true;
ods.TypeName = "Bll.InvestmentProductSvc";
ods.DataObjectTypeName = "Bll.InvestmentProduct";
ods.SelectMethod = "GetList";
ods.SelectCountMethod = "GetListCount";
ods.StartRowIndexParameterName = "PageIndex";
ods.MaximumRowsParameterName = "PageSize";
ods.EnableViewState = false;
ods.SelectParameters.Add (new Parameter("SearchString",TypeCode.String, SearchString));
ods.SelectParameters.Add(new Parameter("PageIndex", TypeCode.Int32));
ods.SelectParameters.Add(new Parameter("PageSize", TypeCode.Int32, gvSearchResults.PageSize.ToString()));
gvSearchResults.DataSource = ods;
gvSearchResults.DataBind();
The Gridview declaration:
<asp:GridView ID="gvSearchResults" runat="server" AutoGenerateColumns="False" AllowPaging="true" PageIndex="0" PageSize="50" OnPageIndexChanging="gvSearchResults_PageIndexChanging" PagerSettings-Position="TopAndBottom">
</asp:GridView>
Are there any reasons for the Gridview not to render a row and not to report an error? I have examined the data returned for the 6 items and cannot find any distinctive differences between the 2 rows displayed and the 4 rows not displayed.
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 notice that my generic list is maintaining only one item, i declared it in the aspx.cs page f one of my forms. I am assuming that each time the page is reloaded when I add an item the list is redeclared. How can I stop that?
View 10 RepliesI've got a class that implements IListSource and returns a generic List of ListItem objects (List<ListItem>). in this list one of the ListItems has the Selected attribute set to true.On the web page I have a standard asp:dropdownlist and I set it's datasource to the getList method of my class and databind it.The problem is that the databind seems to loose the selected Item and the first item in the generic list becomes selected.
