Mar 1, 2010We are developing our application on a 64 bit server. We are using a dropdownlist to filter and display departments in a htmltable(hide and show rows) on every selectedindexchanged event.
The issue is it is firing properly for the first time, but it is not doing a post back there after. We have even given autopostback=true. We are using AJAX for hiding and showing the rows of the htmltable.

Forms Data Controls :: Dropdown List Not Passing Info To Details View?
Jan 12, 2010'm using a textbox to get the first 5 letters of the name.
An sqldatasource then finds the people who have names > than the five letters and picks up their ID numbers as well as their names.
After that I use a second sqldatasource to get one individual from that dropdownlist's persons name and id number and then using a detailsview I display that person.
Well both sqldatasouces work fine but it just does not pass the ID number when I debug it.
Forms Data Controls :: How To Validate A Text Box (if It Is Blank) Inside A List View Row, On Selected Index ?
Feb 8, 2010i have a drop down list and a text box, inside a listview row (and this is a repeating layout). i populate each dropdownlist with same contents ( these contents/items come from a custom collection object).
i have added a required field validator in the listview's item template, that has its validation group = the validation group of the drop down list, and validates if the textbox is blank or not. this validation takes place on the selected index changed of the drop downlist for that row.
1. on selected index changed, EACH dropdownlist validates only its corressponding textbox perfectly (which is what i want)
but if i enter some text in one of the textboxes after doing 1, the dropdownlist for THAT particular row, assigns the correct value to the text entered. but for other rows (for which i changed their corresponding ddls to test the required field validation and for which the text boxes are still blank), their ddls by itself assign the values to the blank text without validating.
markup of code for listview is [Code]....
code behind for the ddl selected index changed is [Code]....
method GetIndexFromId retrieves index of the custom object inside a collection depending on the Id (which is a property) of the object.
i notice that the ddl selectedindexchanged is being hit as many number of times as many rows i change (i.e as many ddls in different rows i change to check the required field validation)
Can The Value And Text Properties Of A Dropdown List Be Used Independently
Mar 8, 2011Can these two properties of a dropdown list in ASP.NET be used independently?
I wanted to retrieve a null value when the user selects some text; I couldn't as it retrieves the Text property whenever the Value is null. Eg:
l1 = new ListItem("Cat", null);
Console.WriteLine(l1.Value);
The output is
Cat
In another situation, when both the properties have different strings, I get the string in the Value property when I use the Text property. Eg:
l2 = new ListItem("Cat", "Mouse");
DropDownList ddl = new DropDownList();
ddl.Items.Add(li);
ddl.SelectedIndex = 0;
Console.WriteLine(ddl.SelectedValue);
Console.WriteLine(ddl.Text);
The output is
Mouse

Web Forms :: How To Assign Text & Value To Dropdown List From Session
Apr 22, 2010First, a user select a country from a dropdown list. The selected item & its value are store in a seesion. Then the user leaves this page.
<asp:DropDownList ID="ddl1" runat="server">
<asp:ListItem Value="US" Selected="True">USA</asp:ListItem>
<asp:ListItem Value="AF">Afghanistan</asp:ListItem>
<asp:ListItem Value="AL">Albania</asp:ListItem>
</asp:DropDownList>
Dim arr(1) as string
arr(0) = ddl1.SelectedItem.ToString
arr(1) = ddl1.SelectedValue
Session("arr") = arr
Later on, the user may come back to the page and change the selection of the country. However, I want the dropdown list to remember the previously selected item and value. The item name and its value are now stored in an array. How do you assign it to the dropdown list as pre-selected.
Database Table Search Using Text Box And Dropdown List With C#?
Feb 10, 2010I'm building a small website using ASP.net/C# and I wanted to know how to implement a simple search feature using a text box and a dropdown.
The datasource is a products table and in the text box I enter the product's name and in the dropdown are the categories. (I have managed to populate the dropdown with the available categories already)
It must follow these conditions:
If both text box and dropdown are blank all products must be listed;
If a category is chosen all products from that category must be listed;
If only text is filled, all products that match are shown;

C# - Save A Binary File In SQL Server As BLOB And Text (or Get The Text From Full-Text Index)?
Mar 26, 2010Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene

Nov 3, 2010I have 2 drop down lists.I have a very simple dropdown list #1 that diplays a title and holds an id value which is a GUID.I know it is getting this value and sending this value as I tested sending it to a label.I have the dropdown list #1 to autopostback to dropdown list #2 that "Is supposed to get" another title and value based on the GUID value of the first dropdown list. for some reason it wont return anything. I have done 100's of these but never based off a guid value.I assume the value needs to be converted to guid before selecting it in the second dropdown list.How can I do this? or is there something I am missing?
