Forms Data Controls :: Order Of The Items In A DropDown List Inside GridView
Sep 22, 2010
I have a DropDownList inside the EditTemplateItem (if the user clicks edit) in a GridView.The DropDownList receives all available rows from the database. My problem is,if the user clicks Edit in the GridView to edit a row and opens the DropDownList Box the original item is not selected but the first one.That means the items are sorted. Have someone an idea how I can solve this issue that the right item / the original is selected if I change to edit mode of the grid view?
In Gridview, Item Template i want to display Dropdown containing Order Status. On Dropdown selection I want to update Status corresponding to that Order. I just want to know how can I get OrderID value(which I had stored in Label in Item Template), in dropdown onselectedindex event. Grid view can't have Edit button.
How do i set a data source of a drop down list which is inside a grid view, snap shot of asp code given below , the Asp file name is DataEntry.aspx and there is method in the DataEntry.aspx.cs called DTB.BindData("Department"). i want to set the datasource to point to this method
I have created an asp.net customizable gridview where user will be able to add and delete data. Now I face some proplem with this gridview. now I want to add a dropdown list (which is dynamically bind with database) inside the grid. I created code and it bind well. when the page is post back previous selected dropdown list value lose and set to selectedIndex=0; For this reason I used if(!page.Ispostback) and put the dropdown binding code inside this. Here I faced a problem. The problem is when I want to add data inside grid the dropdownlist missin bind. How can I overcome this problem? For your kind observation I given entire code below:
I have a text box placed inside a gridview(template) . I need to update its value by a dropdown list event (Selected Item Changed event) placed in the same gridVew. But The problem is that , I need to update the text box of the same row the dropdown list (whose textChange Event haas been fired)
I Have the gridview control with 2 dropdown list and 2 text boxes,When the textbox chnaged event happen 1 row will create and the dropdown back to initial values( its not retaining the selected values),I am binding the control after text changed method,Is there any properties needs to be set or any other way we can retain the values in postbacks?
On my website, registered users can make a profile about themselves suchas name, Favoirite color, hobbies, etcI have a DataTable called User which hold this information.also there are other datatables for Hobbies and Colors which list all possible options.To let the user update their choices I have a FormView in Edit mode on the aspx page whichis binded to the UserTable with a GetProfileByUserId Method and objectdatasource.
Within the formview, i have added drop down lists that are binded to the hobbies and Colors tables so they can edit their previous selection.On clicking Uodate update formview calls an Update Method that adds new selections to the User databaseNow I have two questionsIs it possible to show in the dropdown list the selected value that the User has already made?If the user only changes hobbies and not colors when they click update will a null value be passed into the data table for colors that replaces their previous selection?
I have a repeater which contains dropdown list in it.
The items in the dropdown list are all the same at fist.
But if i select a item in one dropdown, then the selected item will be deleted in the other dropdown list.
For example A, B, C, D,E are the five items in dropdown list, and repeater has three lines.
If A is selected in the dropdown list in the first line of repeater, then the dropdown list in the other lines will only have four items to select, they are B, C, D, E.
If then D is selected in the dropdown list in the third line of repeater, then the dropdown list in the second line will only have B, C, E to choose.
I can do this in csharp code, how can i do it in .aspx page?
I am using a dropdownlist inside Edit template of a formview,, the problem it is not saving the value ,, Here is my code : I am only updating the (status)
I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.
The example is given below( I am reading the book Sams Teach yourself ASP.NET 2.0 by Scott Mitchell. page 628)

I have been trying to get the Re-order list to work using the following tutorial (but in VB instead): [URL] The list is displaying properly, but none of the items are moveable. My code is pretty much exactly the same as the tutorial.
I have packed the access 2007 project management database and moved it to SQL Server. I'm aware that SQL doesn't populate dropdown lists for the Status and completion Percentage columns. I have to have this done by April 21 and my professor is just now telling me he won't accept the textbox inputs due to data integrity and I don't have time to rebuild this entire site.
i have a drop down list that will be used to filter a datatable, i would like to populate the ddl datasource from Unique values from the datatable for the grid.
Is it possible to SELECT from the grid datatable 2 columns with unique vals? like Select custId, CustName groupby custId, CustName ?
i have 4 text boxes and 2 dropdowns are there when ever i fill it all values should place in grid view., after entering of 5 or 6 records, i click on SAVE button then ,i want to save those values in to Data Base ,which are at Grid view.....
I have a gridview and I do Add, Modify and Delete operations. I am comfortable adding and modifying any text or date value. Now, I have a dropdown list to be displayed. I need to add and modify. The contents in the dropdownlist is fixed. Below is the code. I know there is a problem in my
I am trying to correct the sort order of my ASP.NET drop down list.
The problem I have is that I need to select a distinct Serial number and have these numbers organised by DateTime Desc.
However I cannot ORDER BY DateTime if using DISTINCT without selecting the DateTime field in my query.
However if I select DateTime this selects every data value associated with a single Serial number and results in duplications.
The purpose of my page is to display data for ALL Serials, or data associated to one serial. When a new cycle begins (because it is a new production run) the Serial reverts to 1. So I cannot simply organise by serial number either.
When I use the following SQL statement the list box is in the order I require but after a period of time (usually a few hours) the order changes and appears to have no organised structure.
My Problam is on Capturing Text Box and Dropdown seleted itam from grid view i create a gridview with Empty DB binding using [URL] this senirio. I only used setinitional value() function and called its in page load as discribed in above lonk. insted of adding New record Button i callled a java scrit code discribed below. and i also create a button (SAVE) to capture a value intered in text box . On this button click event i try to capture a textbox and dropdown value like
for (int i = 0; i < Gridview1.Rows.Count; i++) { DropDownList sen_to1 = (DropDownList)Gridview1.Rows[i].Cells[1].FindControl("DD_sento_org"); TextBox Add_to1 = (TextBox)Gridview1.Rows[i].Cells[2].FindControl("Txt_addto"); int Add_to = Convert.ToInt32(sen_to1.SelectedValue); String Addd_to = Add_to1.Text; }
but its not working i can not go inside loop.
<script type='text/javascript' language='javascript'> function AddNewRecord(keyCode, obj) { if (window.event.keyCode==13 )var grd = document.getElementById('Gridview1'); var tbod=grd.rows[0].parentNode; var newRow=grd.rows[grd.rows.length - 1].cloneNode(true); cleanUpInputs(newRow); tbod.appendChild(newRow); } } return false ;
