Data Controls :: Read Multiple ExcelSheet And Bind It To Multiple DropDownlist Using ClosedXml?
Feb 25, 2016
I am not able to find the projects related to working with excel sheets by using ClosedXML to refer. I have an excel book which contains two sheets.
In sheet 01: In column A: In B: In C:
Student name01 Student's phone number blabla
Student name02 Student's phone number blabla
Student name03 Student's phone number blabla
In sheet 02: In column A: In B: In C:
course name01 computerscience blabla
course name02 dhfsthshbstgs blabla
course name03 garsfghsefrgs blabla
now, I would like to see in two comboboxes (all the words/text presented in the column A) from two sheets, the student name and course name and then I want select any student name and course name of my choice. Afterwards, when I click on a button, my program should display the students phone number and the course name (from column B from both sheets) and related things present in the Column C D E.. of the selected things in combobox in a label or a in a textbox.
PS: I solved the following problem: I can select student name in one combobox and print the the corresponding data from the only one column B (but I worked only with one sheet). It is bit complicated for me to continue with two sheets.
I have a one combobox and 3 textboxes and one sql datasource.
When I select the name in the textbox I want to show the values in the relevant textboxes. For instance, in the combobox when i select the Name of the employee the relevant information about this employee is shown in the 3 textboxes, i.e. age, cell #, extension.
I have two ListBox in my ascx file, I fill them with some data (no problem here), I make them multiple and increase the size, below is my code.
[Code]....
I use some jQuery code to exchange element between them (Here too, no problem). My problem begin when I post my form, I'm unable to get the data from the DropDownList with attribute multiple or size. I tried in my controler to add a FormCollection parameter, I can see every element in my form except those select tag with more options than id and name. I tested to put a manual select tag in my code with only an id and a name then add size and multiple attribute, when there is only id and name I can get the value but when there are more I can't get my select tag in the FormCollection
Also I need to get all the value in the ListBoxand not only the ones who were selected. I have been searching answer for 2 fays now... Without success, I only find resource on how to show ListBoxbut not how to get values from them in mvc web site and I don't find any resources who talk about multiple selection ListBox, I think I'm a bad searcher but....
I am working on Online shopping website where end user can select multiple items at a time and i need to show them in Cart-item where he has selected his choice items. I want to do this by Cookies in that As user clicks on Add-To-Cart button it gets stored in cookies and in the Show-My-Cart-Item page it shows all the selected items in GridView format.
But I am unable to get all the cookies values except DropDownList Value. And in gridView I get only last ddl value. Though I have used foreach loop But it does not work. How we get all the records in gridview.
Apparently I am trying to do something that is a little unorthadox here. I am trying to use multiple arrays and bind them to one repeater in C#. I would think that there has to be a reasonably easy way to do this but I can not seem to find it anywhere online. This is what I have so far (that works). How do I bind multiple arrays to this one repeater though?
i m trying to bind my both grid with two tables which are in dataset i m trying but when i m binding my gridview it's always binding the second table see code
[Code]....
i already tried to bind both the gv1 and gv2 they both are displaying same table i.e department
Select tbl_name.name,tbl_midname.midname,tbl_last.lastname As name From tbl_name inner join tbl_midname on tbl_midname.id=tbl_name.id inner join tbl_last on tbl_last.id=tbl_name.id where tbl_name.id='1'
I have a complicated report that nests six deep and so really hits the database hard. I want to use SqlDataReaders NOT DataAdapters and DataSets because I don't want big tables in memory.
MARS can get me the data fast, all from the one connection. But all the examples show it binding to a treeview.
I want to bind it to nested GridViews (six deep!).
Any examples of MARS binding to nested gridview/list/repeater controls of any kind?
I want to be able to show the record that was just inserted after add_button_click event. I run the insert from mycommand and then set mycommand2 to run the read to populate a details view. I have a feeling I am going about this the wrong way. The insert fires correctly but the details view does not populate.
I am trying to display a gridview with element names bound to a datatable (transformed from OracleReader) and also display two contact dropdowns inside the gridview. For each record in the datagrid i want to display these dropdown lists that will also be bound to two different datasources. How would I accomplish this?
i have 4 dropdown controls.i have to search for data from ms-sql by selecting the dropdownd if dropdown has all values then ihow an i write query in where condition?
