I have a GridView on a page for maintainance of the database (mdf). Under this GridView1 I have a FormView1 where I use the ItemInsertTemplate to Insert new rows in my database (which shows the data in GridView1). The first textbox (BIDTextBox) i have on this template, contains text which identify a person. I would like to have a routine which checks if the same value that is entered in the BIDTextBox allready exists in the database. This routine should be fired upon leaving the control BIDTextBox.
I have tried with some stored procedure in my database, but that dosn't seem to do the trick. The most logical to me seems to do a loop thru my table "Ansatte" in my database using sql, selecting any occurence from the field "BID" in my table "Ansatte" that is simillar to the text entered in the BIDTextBox.

This is with ASP.NET Web Forms .NET 2.0 - I have a situation that I am not sure how to fulfill all the requirements. I need to update an img source on the page if selections are made from a drop down on the same page. Basically, the drop downs are 'options' for the item. If a selection is made (i.e. color: red) then I would update the img for the product to something like (productID_red.jpeg) IF one exists. The problem is I don't want to do post backs and refresh the page every time a selection is made - especially if I do a check to see if the image exists before I swap out the img src for that product and the file doesn't exist so I just refreshed the entire page for nothing.QUESTION:So I have easily thrown some javascript together that formulates a string of the image file name based on the options selected. My question is, what options do I have to do the following:submit the constructed image name (i.e. productID_red_large.jpg) to some where that will verify the file exists either in C# or if it is even possible in the javascript. I also have to check for different possible file types (i.e. .png, .jpg...etc.).not do a post back and refresh the entire page
I created this simple dynamic data form using Dreamweaver cs4, ASP VB technology and a MySQL Database: I love all of the extended functionality that VWD 10 provided, but the most important functionality for me is to be able to completely design a dynamic data table any way I want.
I noticed after researching extensively that the GridView, ListView and DetailsView templates still leave me very limited in what I can design. My question: is there a way for me to design a table in a details page with record placeholders that will be fetched from a master/detail page set?
i have a UP and DOWN buttons ouside a gridview and a checkbox inside the templated field .I will check the checkbox to sleect a row , after that if i click on UP button the checkbox above the selected checkbox should be selected.
same with when i click on DOWN button the checkbox below the selected checkbox should be selected.
I have a check box in the grid.IF IsChecked has a value checkbox should be checked else not.Should i check the check box in the ItemDataBound event or will it get checked automatically.
I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.
when click save button,I want to save the textbox values to database table..If the record is already available then just update that value... I have the code for insert and update..but i don't know how to check the already existing record..I need ,check existing record using only auto generated id
I have loaded up a gridview object with data. I have turned on Edit on the grid. It lets me edit the data, but I also want to put some code to check for correct data in each field. I tried to assign a requiredfieldvalitor, comparevaliditor but they don't work. Is there an event I can capture to fire up some code before the grid sves my data?
i need to check if some parameter exist in Request.Params any one know how to check that? dont use request.params["para"] != or "" i am not try to check if value exist, i need to check if the parameter himself exist before the checking if his not null or empty.
I am in a situation that i cant solvecos i am new to VB.net. I have a page with both a Detail and Grid view. The Detalview does the inserting to display it on the grid view. My table(Using SQL Server) has 3 field Username, Month and Allocation. I want to give an allocation to a user, but if the user already has one for that month, i want it to cancel.
I'm trying to make checkboxes check if they exist in a table.
What I'm initially trying to do is to list the values is a table e.g. product types, and then if a product has those types assigned to it mark the check box as checked. e.g.
Products Table
Prod No Prod Name
1 Silver Bag
2 Black Bag
3 Red Hat
Product_Types Table
Prod_Type_No Prod_Type_Name
1 Bag
2 Leather
3 Hat
Associated_Product_Types
Prod_No Prod_Type_No
1 1
1 2
2 1
3 3
So When I select product 1 (Silver Bag) it shows 3 check boxes for the product types and prod type 1 and 2 are checked as they exist in the Associated_Product_Types
My problem is I cant figure out how to mark them as checked based on the values in that table.
System.ArgumentOutOfRangeException: 'DropDownList' has a SelectedValue which is invalid because it does not exist in the list of items.this question has been for a long time ago but seem no actual answer for it except for catching the exception.I don't want just catch error instead of check first whether the value exist in drop down list. My scenario was different from the other. my data source is bind to a datatable, all is in hard code.
