Forms Data Controls :: Populating Gridview Bases On Results From Another Gridview?
Jun 14, 2010
I'm not sure how to search for what I'm seeking, so I'm hoping to be pointed in the right direction.
I have 4 gridviews that contain the same 3 rows of data. For each gridview, I need to create a seperate gridview that will do some calculated values on the parent gridview like A3-A1, to put it in spreadsheet terms.
And at the very bottom I will have a total gridview control that will sum up each row from the parent gridviews. And under that gridview a final gridview to perform the A3-A1 calculation.

I am drawing a blank and need some direction.I am putting together a simple website that has a single DropDownList that is DataBound to table inside of a FormView Template.What I want to happen is when the page loads, it runs the SELECT statement and displays that result(which it does, so that part works).Where I am stuck is that if I Click the DropDownList and select another item, and display the results of that selected item in the associated Databound controls.My code is below;

I have a Gridview that has a template field containing a bound textbox (fieldname is 'Status'). I have an extra column containing an update button, which is designed to update the db with whatever is in the textbox.
What's happening is that when I load the form, the textbox is blank, even though there is existing data in the fields. If however I click the update button, all the textboxes in the Status column update and populate with the correct data from the database. I guess my question is why would bound textboxes not populate until an update command is run?

I am developing an application using Sharepoint Designer.I need to retrieve data from a database for display on the screen.The way I am hoping to implement this is to have a Text box from which data is taken and at the click of a button passed to the procedure (which is within script tags) which calls a stored procedure passing it the value entered in the text box.The problem I've having is that the gridview is not displaying anything (i.e. other than text i entered in the EmptyText property of the gridview ("There are no records").
Below is my code
<%@ Page Language="VB" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-

I'm generating a number of calculated arrays in the code behind a ButtonClick event on a particular page. Stuff like:
Dim Delta(,) As Double = New Double(nPer - 1, 0) {}
For i = 0 To nPer - 1
Delta(i, 0) = Delta_Buckets(i, 0) + fwds(i, 0)
Next
What I want to do is convert this to a datatable and use this as a datasource for a gridview in a different page.

VS2010 Ultimate ASP.NET 4.0 Web Appliction project
I have a simple aspx page with a GridView Bound to an ObjectDataSource utilizing a class object that returns a DataView.
There are no errors generated, but the GridView does not display any rows. If I check the return value of the ObjectDataSource in the Selected event in the Immediate window (?CType(e.ReturnValue,DataView).Count), there are 51 rows. However, (?Me.GridView1.Rows.Count) shows 0 rows. The exact same page in VS2008, ASP.NET 3.5 works fine. how to get the GridView to display the rows? What has been done to the GridView in 4.0?

during edit mode i populate the drop down in question with data based on a value selected in another drop down also in the gridview, all works find, but the paramater is not being updated with the selected value, i think this is because i do not call any Bind in the aspx side.
<asp:TemplateField HeaderText="Build Types">
<ItemTemplate>
<asp:Label ID="lblBuildTypes runat="server" Text='<%# Bind("BuildType") %>'></asp:Label>

I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?

I have a gridview on a page with search boxes at the top.
The wildcard for these is % so in every serach box I set the default to be % so that when the page loads all records are shown and then they can be narrowed down by what you search for but when the page opens the gridview does not show all results.
Here is my code:
<%@ Page language="C#" masterpagefile="MainContent.master" title="Electrical Storage" EnableEventValidation="false" %>
<asp:Content id="Content1" runat="server" contentplaceholderid="Content">
<div id="Rightside">
<h2>Search Electrical Storage

My sql statement is not functioning correctly. The gridview does post the items correctly but the results are not correct. Can someone assist me with the sql statement where I'm going wrong with it?
I only have one being reffer to the code because I was testing to see it work. Eventually, the search will be base on multi select and the selected items are going to the stored procedure to search for the proper records.

I have two dropdown lists that I am using to filter a gridview. I gridview is populating based on a query
select [AnnotationNumber],[AnnotationBy],[AnnotationType],[BusinessUnit] as Unit,[ErrorType],[ActualAgencyError],AnnotationComments,[sgkComments],[ActualAgencyError],Cust from vw_GridviewSource where Name = '"+@Name+"' and AnnotationDate = '"+@Stage+"'";
SqlCommand cmd = new SqlCommand(query);
gvSummary.DataSource = GetData(cmd);
The @Name and @Stage variables are the selected values of the dropdownlist. When I start I get the two drop down lists on my webform. When I select the values from the dropdownlists, nothing happens. I get no gridview. I added onselecedindexchange event both dropdownlists and even after both are selected nothing. I debugged the code and found that there is a point where the value is correct, but I still don't see the gridview. I have alsochecked the query associated with the databind and it works perfectly when I check it in SQL. I am enclosing all the code from the aspx.cs and aspx.

I am using visual studio 2010, asp.net 4.0 (c#)
My problem is:
How do I display results from my database on a gridview based on the selected row of another gridview.
For example, I have a e-shop web app and I have a product categories table in my database displaying the data on a gridview.
I want to be able to click on the select button on each row and use that event to populate another gridview based on the ID of the product category that is clicked. E.g say the 'CDs' row is clicked, another gridview shows all the different CDs.
As a result, I need the select(sql) statement for the second table to be dynamic based on what the user clicks.
Has anyone done anything like this before?

I am trying to figure out how to bind my link results to a datasource so it can manage/update/edit/insert/delete without me having to do manual coding for all of it. Is this possible?What am I doing?I have used the LINQ to Active Directory to access our AD accounts. I need to make this a webpage frontend of basic search and managing functionality. I have it searching now and adding the results to a gridview but edit is not working now. I was looking online and I saw something about being able to bind linq results to a datasource and then using the datasource to manage all the information for me. Resources I am using:

I 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();

I am working on a site using .aspx controls. Currently I am working on a search feature which searches my database of records and produces all applicable results to the search. Everything works as planned. I have recently added the EmptyDataText line to produce a specific output anytime no results are found in the database. However, I would like to be able to alter/change the appearance of the EmptyDataText output and cannot figure out how to do so. For example, if no results are returned from the search, I would like the EmptyDataText to produce an output of something along the lines of "Your search has produced zero results.
double check your spelling and try your search again." I would like to change the font color, font size, and possibly the thin box which is automatically produced around this output. Is any of this possible? If not, is there another way to produce the desired results? Ultimately, I would actually like to have the results actually use the terms which were input to the search within the EmptyDataText results when no search results are found within my database. For example, if "widget" was used as a search term and "widget" was not found within my database then i would like the results page to state something along the lines of: "Your search for 'widgets' did not return any results. check the spelling and try your search again." Does anyone know how to do any of these things using ASP.Net?

I have a dataset that has two datatables. In the first datatable I have EmpNo,EmpName and EmpAddress. In the second datatable I have Empno,EmpJoindate, EmpSalary. I want a result where I should show EmpName as the label and his/her details in the gridview. I populate a datalist with the first table, and have EmpNo as the datakeys. Then I populate the gridview inside the datatable which has EmpNo,EmpJoinDate and EmpAddress. My code is
[Code]....
My Design is
<asp:DataList ID="Datalist1" runat="server" DataKeyField="EmpNo">
<ItemTemplate>
<asp:GridView ID="Gridview1" runat="server">
</asp:GridView>
</ItemTemplate>
</asp:DataList>
I do not get results in the gridview, instead have errors. I tried then placing the bound field
<asp:GridView ID="Gridview1" AutoGenerateColumns="true" runat="server">
<Columns>
<asp:BoundField DataField="EmpNo" />
</Columns>
It throwed an error stating / A field or property with the name 'EmpNo' was not found on the selected data source.

I am a newbie at entitydatasource and have a few questions:
1. Currently, the gridview doesn't render. Why is that?
2. How do I wire up the gridview to grab the values of ddlsearch and txtSearch and return results using those values from my entitydatasource?
3. Ultimately, I want to encapsulate this gridview in a wizard step wherein the user checks items they want and those checked items are used in the next wizard step.
