Data Controls :: Populating GridView With Two DropDownLists
Sep 11, 2013
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 have a page with a data repeater. Each row has a dropdownlist for the user to select a value and the values in every dropdown are the same. I also have an SqlDataSource which each dropdownlist gets its values from as its created. Everything is working as it should but for each dropdown that is rendered a seperate call is made to the database.
suggest a better way for me to do this that means only one call to the database for all dropdowns rendered?

I want to filter my gridview using two parameters that come from Dropdownlists. I bind these drops with two linq queries and next I would like to filter my gridview with query that has two parameters that comes from selected values from those drops. Everything is inserted in UpdatePanel. Here is my code:

I have a gridview that is currently showing 20 lines per page. Each line has several fields in it, three of which are dropdownlists. These dropdownlists are populated with a SQLDataSource and then the selected value is bound to one of the gridview datalements.
The problem I'm running into is that the page is very slow to load. I believe this is because of the large dropdownlists (and possibly because there are roughly 60 of them, each of which is executing a SQL query to populate the list of available values). The file size that is being transmitted over the web is just over 1.25MB in size, again from the large amounts of data in the dropdownlists.
Is anyone aware of a technique by which I could only execute the query from the SQLDataSources that populate the dropdownlists' available values once and then reuse the results of that query to populate the relevant dropdowns? Ideally I would do this on the client side so it would also limit the amount of text being transmitted to the client browser.

I have a gridview with 4 dropdownlists and 1 label in each row. Suppose , text fields of each dropdownlists are a,b,c and value fields are 1,2,3 respectively.
In each row,label text is the sum of value fields of selected text fields of 4 dropdownlist.
For example,If selected text of 4 dropdownlists of a row are-b,a,b,c.
Then the label text of that row will be 8.(value field of b=2,a=1,c=3 , so b+a+b+c=8)
Whenever the selected text of any dropdownlist changes,corresponding label field also will change.
How can we do this in asp.net with C#?

On one of my pages I display a Gridview. This contains a list of questions generated by a SQLDataSource, with a dropdownlist on each row containing the answers for that question. The answer values can be different depending on the question, so I populate them in the RowDataBound event for the gridview, using question information.
As the list of questions is longer than the page I have placed the gridview within a Div which allows me to use scrollbars to navigate the gridview. I also use some methods to preserve the location of the last question answered - so that on answering a question, the gridview does not reset to show the first part of the gridview.
This works fine for IE7, which is what I have been using for the development, and which part of my customer base uses. However, the other part of my customer base uses IE6, which causes a problem.
When an IE6 user attempts to answer some questions, they run into issues. Should they scroll down the gridview, when they select a value from a dropdownlist (Effectively, when they answer a question), there is a postback and all of the visible (i.e. onscreen) dropdownlists appear to be cleared. However, on mousing over any of the dropdownlists, their value is then shown. On using either the scrollbar, or on using the mousewheel to scroll the gridview, all the dropdownlists are 'refreshed' and their values are shown.
At no point does the application appear to lose the data, it is just not showing it until there is a mouseover or the gridview is refreshed. Another odd aspect of this is that this does not apply to the first 5 rows of the Gridview. Any of these can be altered without there being this display issue. Should the gridview be scrolled enough to show some of the first 5 rows and some subsequent rows, only the subsequent rows will have this display issue.
I have tried various things to correct this - originally I called my retrievescrollposition method on the SelectedIndexChanged event of the dropdownlist, but have since moved it to Page_Load as the Else branch of if (!IsPostBack). I tried rebinding the DropDownlist in the SelectedIndexChanged event, but this only helped with the Question I was answering - the display of any other onscreen questions was still affected.

I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists.
For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List.
BTW i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database.

I am filling a gridview with data.
column 1 is a dropdownlist <ddlGrade>
column 2 is a checkbox <cbxNeverAttended> not visible
column 3 is a textbox <tbxLastDate> not visible
in the 'GridView_RowDataBound'
i determine if a ddlGrade value already exists and if so, make it selected in the dropdownlist
also, if the value of ddlGrade is a "U" I make cbxNeverAttended and tbxLastDate visible
However, if cbxNeverAttended or tbxLastDate are both empty strings (and ddlGrade has the value "U"), I want to disable all instances of ddlGrade in the gridview (essentially forcing the user to enter a value for cbxNeverAttended or tbxLastDate before moving on to enter another ddlGrade).
But I have been unable to figure out a way to accomplish this on the 'Gridview_RowDataBound',

<asp:DropDownList ID="ddlday" Width="100px" runat="server" CssClass="iselect" Autopostback="True"
AppendDataBoundItems ="true">
<asp:ListItem Text="--Select--" Value="0" />
<asp:ListItem Text="Full" Value="1" Selected="True" />
<asp:ListItem Text="Half" Value="2" />
</asp:DropDownList>
I have a dropdown in gridview. I bind the gridview after not ispostback condition. Now if i select drodown lsit value "Full" from the first row of gridview i need all other rows of dropdown in gridview to be selected "full" programtically and after that if the user wants to change other row dropdown to "half" then he can change it.

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 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?

I read your article on ASPSnippets and everything worked great. I am having one problem and this is preventing me from moving forward. When I select the edit for a row (I only have two columns), the drop down comes back blank (no records). I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list? I can't tell if the column automatically adjusts because I am not returning any records.

using System.Collections.Generic;

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?

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>
