Web Forms :: How To Pass Selected Value Of DropdownList To A User Control On Postback
Feb 25, 2010
I need to create a user control which will be loaded according to the selected value of a dropdownlist. The Dropdownlist is not the part of Control. I want to pass the value of selected value of dropdonwlist to my user control and the user control will load according to the Value. For not postback it work fine. But when the page is postback, that is when i select a item form dorpdownlist, the user control is not loaded.

This must be something not very difficult but I am pretty new in C# and have a problem to resolve.
I have tree dropdownlist controls. One of the control values are dates. When client selects all three drop downs then I am passing values to SQL table. Everything works but one. Date value shows 1900-01-01 instead of selected value in SQL table. I am not passing date value correctly but can't figure out how to do it.
Following is a code:

I am building a composite server control that currently only has a TextBox and a DropDownList. Here is the code in all its foetal glory:
[Code]....
The control appears to work correctly across postbacks, that is until declarative values are set, e.g.:
<squee:Address runat="server" ID="a" Street="123 Fake St" State="VIC" />
After this, the text box continues to work correctly, but the _state member does not pick up the posted back values and instead just sticks to the declared value. I've checked the raw posted values in the Request object, and the new value for the list's UniqueID is there, but _state doesn't pick it up.

I have a survey form, survey.aspx, that looks for information about 3 different people (hiking guides) who are all contained in a single DropDownList. Instead of repeating the list over and over, I figured I'd put them all into a single user control, GuideList.ascx, shown here.

The form has 3 instances of this User Control. Here’s what the first one looks like:

In trying to access the value the user chooses from the DropDownList, I have created the following code
in GuideList.ascx.cs

In Survey.aspx.vb, I have the following, that often blows up because it doesn’t like G1:

I have tried using GuideList1 and GetGuide and GuideList1.GetGuide and GuideList1.G1 and all sorts of variations, but cannot seem to figure out what I'm missing to access the value of the DropDownList.

I have a user control that has some drop down lists. These DDLs are used by the user to filter their product search on my search page. A button is used to post the form and get the results of the product search. Those results are displayed on the results page, which also has the search filter user control on it. I'd like the results page to have the values of the DDLs be preserved from the search page. Example: user selected color of red and size of large on the search page. When the results page is displayed, I'd like the selected color to be red for the color DDL and the size to be large for the size DDL. How can I do this?

I have a DataGrid that has a dropdown list in an ItemTemplate. Basically, users select a value from the dropdown for each row of the datagrid. When the page is posted back, the selected index of the dropdown list is always reset to 0, and the items are re-bound.
Does anyone know why this might happend? The dropdown items are hardcoded, so there is no external data binding that happens on post back.

I have 2 - DropdownList controls, which i am filling at severside when page loads. After the user selection in DropdownList1, i am changing the contents in DropdownList2 values. This validation (i.e. changing the contents of Dropdownlist2 values) am doing in Javascript Clientside. But on postback i am not getting the values in DropdownList2. When i say "DropdownList2.Items.Count;" getting "0". I tried to put the contents of DropdownList2 in ViewState on pageload. But i am getting Serialization error at runtime "Viewstate["PersistValues"] = DropdownList2;". I am using html input hidden control to pass the values from server side to clientside for my validation. Now, to meet this requirement i am Binding the DropdownList2 at postback again with first DropdownList1's selected index (This is repeat of logic which i have done in Clientside).

I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.

i have a master details gridview setup, meaning a gridview inside a gridview, but the inner most gridview has a template field hyperlinkbutton control and i set the "CommandName" of the hyperlinkbutton to "Select".
so what i need to do is to get the selected value of the inner most gridview and pass it to a label control which is located outside of the two gridviews.

I wanted to know if it is possible to pass multiple selected values from Checkboxlist to SQL table so each selections goes into separate row in the table.
I tried it using the following code (to pass ShowDate value) but it enters value only if I make one selection. It gives me an error message if I make two selections and try to pass it to SQL.
