i have a list box (listbox1) populated with some values.i also have a table with some values.I'd like to show values from table which are NOT IN listbox1.here's a code. I see what the problem is. Just can't understand what is the solution.If I have one value in listbox it works fine, but if more than 1 it messed up, since it tries loop several times.
[Code]....it works fine. The only thing: If I want to update some properties of item, but do not update name(just leave name the way it was) it still fires the validation, and my update cannot pass validation since this name is already exists.i have a listbox populated with values from linqdatasource (or from datacontext using code-behind) Also I have formview which allows to insert new values to database.When I insert new value in the database, this value doesn't show up in listbox until I recompile project/restart browser. When i refresh page nothing happen. Only old values are visible. Id like to have more dynamic page. I tried updatepanels. Maybe I need somehow refresh database connection first?
using gridview to show data from table. on the aspx page i want to hide/show image depending on the value of one of the fields of a table. for e.g. say is_new=1 then show else hide where is_new is table field.
for this on aspx page i have one img element whose initial visible property is set to false. Now at runtime i want to show/hide image depending on value in each record. So what coding needs to be done and where?
I have a GridView and a linqdatasource. The GridView is editable and when the user clicks to edit a row I want to concatenate two of the fields in the linqdatasource and place it in a single textbox.
I have a problem. I'm using a gridview to show some values of a xml.
this is my gridview
[Code]....
The last templatefield i want it to work as a deletebutton... Onclick it will erase the row of the xml.
My problem starts because i dont know how to get the number of the row that contains the button that was clicked or the id that is passed by datakeyvalues on the click of that same button.
if imagebutton had the value property i could send the id by eval by i know it doesn't have that property.
ex: value="<%#Eval("ID")%>"
So what do you thinks it's the best option, maybe do a redirect and there make the onclientclientclick attribute and the code to delete the xml row or can i do that on the codebehind of the page where my gridview is...
I am using VB in Visual Studio 2008 and a ASP.NET web page.I have populated a gridview with data aquired from form data. For use in the current session. I am not bound to any database.I would like to pull the headers and also the data one row at a time.How can I do this?I thought I could just do something like myString=Gridview.SelectedRow.Cells.Item(1).Text
I am trying to populate a gridview using two tables. I also have a strongly typed dataset and used the method on this page: [URL] the problem is that, when i try to use two table the gridview does show up (I checked through debugging that the datatable comes back as empty).
I have a gridview that have some boundfield and a table inside a tamplatefield. That table have 6 input (hidden) that binds when the page load.
How can I get the values of those 6 input inside the table from server side?
I know how to get the boundfield values , with
Dim selectedRow As GridViewRow = GridDetail.SelectedRow Dim fName As String = selectedRow.Cells(1).Text Dim lName As String = selectedRow.Cells(2).Text Dim Iname As String = selectedRow.Cells(3).Text
Updates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.
Here's the code for the Item and Edit templates. The code behind is below this.
I am building a little app to upload a picture and various downloads for different file types for the photos, but I also need be able to select the catergory they will go into. So I have two tables one that stores the catergory names and one that holds the paths to the photos and downloads the tables are related through the catergoryID.
What I need is those catergories to show up in the photo's and downloads table so that when I go to upload the photos I will be able to select the categories.
I have also built the DataSet and the Business Logic.
I am using an ADO Entity Model for my ms-sql database.
My database has a Resellers table which has ResellerID (primary key, int) and Name columns along with other data.
I also have an Orders table which contains OrderID (primary key, int), OrderDate, ResellerID (foreign key to Resellers.ReselerID).
If I just do a query like:
[Code]....
I am able to reference order.Reseller.Name just fine with no problems.
However I have an EntityDataSource on my page as follows:
[Code]....
Notice the Include="Reseller" attribute in the datasource... I also have a GridView tied to that datasource as follows: I cut some of it off for breavity:
[Code]....
Now what I have listed above will run with no errors, but what I want to do is replace the column that displays "ResellerID" with the equivilant to order.Reseller.Name. In other words I want my grid to display the reseller's name rather than the numeric ID.
I have tried to change the DataField to "Reseller.Name" but that will generate the following error:
A field or property with the name 'Reseller.Name' was not found on the selected data source.
Is there anyway to do this without me writing a custom select statement in my code behind?
I want to show the textbox which is in Gridview, eventhough the Datasource[Table] of the Gridview is empty.The user has to enter some value and save it in the table. My problem, when there is no value in the table, textbox is not shown. I am using Linq, So the Gridview has to bind using Linq list or table The objective of the task:
1. Show the blank textbox when there is no data in the table.
2.A Addnew Buton has to show, If the user clicks the Addnew button, One more textbox has to shown and user can enter the second input.
I am fairly new to ASP.Net and web programming in general and I am having issues trying to add values from a dropdown list in my gridview to another table.
Here is my scenario. I have 2 tables in my SQL Express DB. When editing the values of table2 in a gridview, I would like to show some data from table1 in a dropdown so users can select a value from table 1 and enter that value in table 2.
I have the Gridview setup to show table2 data.
I created a field template and inserted my dropdown list and linked it to my table1 data source.
When I run my web form, I can click to edit one of the fields in the gridview, and my dropdown list correctly displays the data from table 1, but when I try to update the table2 with the dropdown value, it doesn't correctly update. The row in table2 never updates.
posting the dropdown value from table 1 into the appropriate field in table2..
Again, I am new to this and have been following the tutorials etc on this site, but can't find one pertaining to this topic.
I need to write a query to populate a gridview with minimum rates in ascending order for a month from three tables.For example i have three tables A,B,C as follows
TABLE A TABLE B TABLE C Id id id Quote_no Quote_no Quote_ no Name Rate1 Equip_name Rate2 E_rate Date R1_rate R2_rate Date
Now if the data is as follows
I need to get the Name from Table A ,minimum Rate1 and Rate2 values for a month in a dropdownlist from date field from Table B and the corresponding minimum rate(E_rate) for Equipment E1 and E2 only from Table C for the month in ascending order group by Name.
TABLE A
id Quote_no Name 1 101 XYZ
2 102 ABC TABLE B id Quote_no Rate1 Rate2 Date
1 101 105 200 12/11/2010
2 102 90 210 15/11/2010
TABLE C id Quote_no Equip_name E_rate R1_rate R2_Rate Date

I am doing a data warehouse project.I have two tables tblA (id, type) and tblB(city, no_crimes, type).I want to create (insert) a number of rows based on the value of no_crimes.For Example, in tblB(Leeds, 2000, murder). SO, I need to insert 2000 rows into tblA by a single INSERT statement (not 2000 statements).
I've implemented a cascadingdropdown solution using the demo video here on ASP.NET.
Below is my code for one of my sub-categories. I want to have my sub category controls hidden and only show them if there are sub-categories (not all categories have sub-categories)
So, my question is how to get the count of the subcategories returned by method below and turn on the visibility of the dropdown control from the web method?
