Forms Data Controls :: Sum Of Selected Items In Gridview?
May 4, 2010
Im using Visual Web Developer 2008 and I have set up a gridview showing data from a sql database, it shows 3 columns, these are: item name, item cost and a check box column to allow the user to select certain items. I would like to have a text box that shows the sum of all the selected item costs.
i am creating a print view using checkboxes that a customer uses to select which items they wish to print. I am having difficulty transfering the selected gridview items to another page. I was using crosspage post.
have a page that has a results gridview where I have all rows with a chekbox. when I click on the checkbox I try to create an excel filethis is method content:
DataTable MyData = new DataTable(); //recorrido sobre los elementos seleccionados6 foreach (GridViewRow row in gvwDbf.Rows)
[code]...
The problem is that excel file is totally empty. When I trace on the error I find that (item on bold above) dt datable has current record as I expected but Mydata table has nothing inside. shouldn't I use import statement? How can I get the row copied? I intend to have a full table made by every record coming from parameters of each query which is performed inside a for each sentence
I will have a gridview with checkboxes and some amount fields. I would like to display the sum of the amount in gridview footer depending on the checked items by the user.
I am trying to put the select command in code behind:
sdsAdd.SelectCommand = String.Format("SELECT Classes.ClassId, Committed, CallNumber, SubjectArea, CourseNumber, SectionNumber, GradingBasis, NumberOfUnits, NetId FROM Classes INNER JOIN EnrollmentAdjustmentClasses ON EnrollmentAdjustmentClasses.ClassId=Classes.ClassId WHERE AllFormsId='4' AND SectionId='1' AND NetId=@NetId AND Committed='True' AND EnrollmentAdjustmentClasses.FormId={0}", Request.QueryString["FormId"].ToInteger32()); gvAdd.DataBind();
When I do that, then click edit to edit the selected item, the item disappears from my gvadd. What am I doing wrong?
I have a Gridview,when i select item from 1st grid it should load in the 2nd grid, here i have done for selecting from checkbox,but when i uncheck it is loading properly,
No you cannot add a third parameter in the Dictionary. It contain Key Value pair data.But if you want to add third parameter then simply use DataTable and add these in the DataTable row.Name of Builder , Title Of Buidler , Builder ID
So how to acheive that task ? so far i did like this :
public void AddNewCMP(string PersonName , string PersonID , string PersonTitle) { var dt = new DataTable(); if (ViewState["CMPDataTable"] != null) { dt = (DataTable)ViewState["CMPDataTable"];
[Code] ....
Now on button click i want to add six drop down values to AddNewRow(value1,value2,value3) method .... how to do that ?
below is the code I have but I want to change the ddl.Deal(dropdownlist) to cbl.Deal(checkboxlist).. How can I loop throught each items if checked. and if all items are checked. to filter my data and show in gridview..
protected void btn_Click(object sender, EventArgs e) { myAPI.myWeb myAPI = new myAPI.myWeb(); myAPI.SearchParameters sSearchParameters = new myAPI.SearchParameters();

I am trying to hide 2 buttons depending on the value in the dropdownlist. It works when the page is initially loaded but chokes when returning to the page sometimes. I have some pretty simple code in the Page_Load event within an If Not Page.IsPostBack statement

I have two gridviews on same page - If a record is selected in Gridview1, I need to unselect a record (if one is selected) in Gridview2 - and vice-versa.
I have a little problem, may be is easy thing , but I don't find way to do, don't understand this it,in one file called search.aspx, I have a two dropdownlist controls working in cascading, one bind the another, the selection of second dropdownlist fill a checkboxlist, user can check or uncheck options, based on what they are looking.the result of the checkboxes selected, bind a DataList,Users can view the results in Datalist, and select it, like this.when user click in item in datalist is send to another file called viewdetails.aspx, and can see details of item.
the problem is when user come back to search.aspx. all controls are reset and user selections disappears, my datalist don't have items is clean, what can i do for keep values ?.
I have code when I click on button I want show the value of selected List item in textbox but following code gisplay the item in alert,,
<html><script>function getValue(){ var x=document.getElementById("sel");for(var i =0; i < x.options.length; i++){if(x.options[i].selected ==true){ alert(x.options[i].value);}}}</script></head><body><selectmultiple="multiple"id="sel"><optionvalue="volvo">Volvo</option><optionvalue="saab">Saab</option><optionvalue="opel">Opel</option><optionvalue="audi">Audi</option></select><inputtype="button"value="Get Value"onclick="getValue()"/></body></html>
I have 2 ListBoxes. 1st SelectionMode is Multiple. Once I select many options from 1st ListBox I can copy it in ListBox2 but i Unable to remove it.
Code :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click For i = 0 To ListBox1.SelectedItems.Count - 1 ListBox2.Items.Add(ListBox1.SelectedItems(i).ToString()) ' ListBox1.Items.Remove(ListBox1.SelectedItems(i).ToString()) it is not removing. Next End Sub
I am using C# ASP .NET 2.0. I have a web form with two DropDownList controls. In my code behind I get data from a DataSet. One column is a string (Month), and another is an integer (StatusID). I am setting the selected item in the each DDL in the code behind by doing this:
[Code]....
I have a button with a Click event. What I want to do in the click event is be able to check if the currently selected item in each DDL (if the end-user changed the selection) is different from what was selected in the above code.
