Forms Data Controls :: Binding SQL Query Results To A Gridview?
Aug 11, 2010I have a gridview that I want to bind the results of a query to it once a user selects a value from a drop down list.
The query selects the same row from the same table but selects different fields based on the drop down list value selected
I get to the query selection but it does not refresh that page with the populated gridview.
Here's the code behind code
protected void ddlQuantity_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection connection = null;
connection = new SqlConnection(ConfigurationManager.ConnectionStrings["PSI_DB_1ConnectionString"].ConnectionString.ToString());
connection.Open();
String nEstno = Request.QueryString["id"];
int id = Convert.ToInt32(Request.QueryString["id"]);
string SQLquery = "";
switch (int.Parse(ddlQuantity.Text))
{
case 1:
SQLquery = "Select Quan1"etc...;
break;
case 2:
SQLquery = "Select Quan2"etc...;
break;
case 3:
SQLquery = "Select Quan3"etc...;
break;
case 4:
SQLquery = "Select Quan4"etc...;
break;
case 5:
SQLquery = "Select Quan5"etc...;
break;
}
SqlCommand Cmd = new SqlCommand(SQLquery, connection);
SqlDataReader Dr = Cmd.ExecuteReader();
if (Dr.HasRows)
{
gvEstQty.DataBind();
}
Cmd.Dispose();
connection.Close();
connection.Dispose();
}
Forms Data Controls :: GridView Data Binding With Nested Query Instead Of Eval()?
Jan 11, 2010I ran into this kind of situation many times without a nice solution. Binding a data source to a gridview and one of the column require nested query. Is it possible to have a callback function other than Eval()?
something like CallbackFunc(Eval("SomeField"));

DataSource Controls :: Binding A Complex Query To A Data Control?
Apr 21, 2010I'm trying to implement a recipe search page that allows users to specify search criteria by selecting checkboxes that match desired recipe attributes. All the data is stored in a database uing tables with 1 - many relationships. Each recipe can have multiple attributes from any of 5 attribute tables. I want to find all the recipes that match the user-selected criteria and display them in a grid. For example, the user may want a breakfast (attribute 1) recipe that is made with fruit and milk (attributes 2 and 3), is low-fat and high fiber (attributes 4 and 5), and takes less than 15 minutes to prepare (attribute 6). The query for this example might look something like:
SELECT distinct recipes.name, recipes.difficulty, recipes.preptime, recipes.cooktime
FROM recipes, recipeMeals, recipeDishes, recipeFoodGrps, recipeNutrients, recipeFixTimes
WHERE recipes.id = recipeMeals.recipeId and recipes.id = recipeDishes.recipeId and recipes.id = recipeFoodGrps.recipeId and recipes.id = recipeNutrients.recipeId and recipes.id = recipeFixTimes.recipeId and recipeMeals.mealId in (1) and
recipeDishes.dishId in (5) and recipeFoodGrps.fdGrpId in (1, 6) and recipeNutrients.nutrAttsId in (2, 3) and recipeFixTimes.fixTimeId in (1)
I' can generate the SQL but can't figure out how to bind it to a grid control. No could I see how to get any of the data controls to build the query for me. Is there a way to say "execute this query and display the results in a GridView"?
C# - Binding DataTable To GridView, But No Rows In GridViewRowCollection Despite GridView Population?
Jun 2, 2010 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.)
GridView Markup:
<asp:GridView ID="gvCart" runat="server" CssClass="pList" AutoGenerateColumns="false" DataKeyNames="ProductID">
<Columns>
[code]....
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.
Forms Data Controls :: Binding DataSet And GridView, Apply Bulk Rows Edit And Update On GridView
Dec 10, 2010I 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.

VS 2010 / C# GridView Binding Twice
Jan 12, 2012I 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.
Is there a way to keep this from happening?

C# - What's The Difference Between Binding Data To The Repeater In The Mark-up Or Binding It Programatically
Mar 4, 2011What'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
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
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")
AJAX :: Tab Container And Binding Gridview

Gridview Binding With Combobox's In Header?
Jul 27, 2010 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.
HeaderText1 | HeaderText2 | HeaderText3
ComboBox1 | ComboBox2 | ComboBox3
DataRow1 | DataRow1 | DataRow1
DataRow2 | DataRow2 | DataRow2
DataRow3 | DataRow3 | DataRow3

Feb 17, 2011I 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.

here is my binding sample.

Binding Tuple Output To The Gridview?
Mar 4, 2011I 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?
