Web Forms :: Find DropDownList Control In MasterPage And Get Its Values
Sep 4, 2012
I have threee dropdownlist's which are varchar in master page and one dropdownlist in current page which is of int datatype. At present in current page I'm using LIKE '%' for all dropdownlist's. I need to pass dropdownlist vlaues as parameter to sql.Â
What i am trying to do is read the value from the search textbox from the nextpage.aspx. When i hardwire a text value to the txtboxsearch, i can read it using the page.previouspage property in the code-behind of nextpage.aspx. But when leave it empty so it will dynamically extract whatever value that's typed there, it doesn't read it. I am sort of understand why it is failing but can't fix it. I have gone through: [URL]
am using master page in visual studio 2005. I want to fetch the drop down value which is there is the master page in my child page using the code below
I have a MasterPage and a ContentPage. On the ContentPage I Similated a TabControl by using a Menu and an IFrame. When the menu item is seleceted it loads in the appropriate WebPage into the IFrame. Now... on one of the WebPages I am creating dynamic controls on Page_Load. But when I refresh or switch menu (Simulated TabControl) back and forth, then I lose my controls and values.
I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain content if a session variable is not null.
I have an ImageControl inside an UpdatePanel. The image changes upon a Treeview located outside of theUpdatePanel. Im using the treeview _SelectedNodeChanged in the UpdatePanel Trigger. When I run the Web Application I get an Error theMasterPage could not find the Treeview for the Trigger.
I have a dropdown list within a listview 'EditItemTemplate' and 'InsertItemTemplate" which I am trying to populate from the database with code behind with ItetmDataBound event. Problem is I am getting NullException when I use this code which works fine for ItemTemplate.
Can anyone point me to where i can find a documentation about css, masterpage and derived pages in VS2008. I used them in VS2005 but it looks like it's almost impossible on VS2008. or it's just me.
GridView gvchild = e.Row.FindControl("gvOrders") as GridView; drplist = gvchild.FindControl("drp1") as DropDownList; // den also same error object reference not set to an instance of an obj
I have a MasterPage in my project which it contains a FormView and the FormView is databound with a Connection String to a SQL DataBase.
This FormView is selecting users information from Database, when the ContentPage is loading, Im trying to get the information from the FormView of MasterPage and load them in Content Page, but it is not working fine for me.
For Example:
In MasterPage I have a FormView such as follow:
Name: Amir
LastName:Zandi
Username:amirzandi
In ContentPage, I have a Label and I want to get the name from MasterPage and replace it with the text of the Label.
I am doing this at PageLoad of Content Page with the Following Code:
[code]...
At the page load of ContentPage, it says that it could not find the FormView1
but after I refresh the page, it works fine.
is there anyway for me to ask the FormView in MasterPage to DataBind and After that, it retrieves the Data from FormView and place them into the ContentPage.
I also tried: fv.databind() but it is not working.
I access querystring values in each content page's pageload method to get Username and Id. Is there a way I access the querysting values from Masterpage's pageload method and each content page goes to Masterpage to get those values without creating any other local variables in content pages? I know this can be done with Session's or view state but I was thinking to reduce redundancy of accessing query string in each content page.
Hello all i have this little issue getting this to work, i have a dropdownlist in asp.net inside a formview and jquery cant find the control im guessing because its inside a form, this is what i got and it works on another page without a formviewi get this errorName 'Country' is not declared
firstly,i am going nuts with this problem. here it is:
i have a masterpage that contains a dynamically populated dropdownlist. i have autopostback =true and an onselectedindexchanged function. users user the dd to choose from a list of accounts that are available to them to edit/view. this portion works great. users pick an option and it postsback with the correct item. the item chosen gets set in the users profile so it defaults to it next time they log in.
now the problem arises on certain pages that use this masterpage. the child page has a timer, an updatepanel, and a gridview inside the updatepanel. the timer tick event fires and calls databind for the gridview. this all works great---EXCEPT, if the timer ticks while i am looking through items in the dropdownlist, the gridview updates, but also THE ONSELECTEDINDEXCHANGED event fires for the dd, even though i haven't actually clicked the dd to change it. just clicked it to make the dropdown active to see its items. once the timer ticks, it automatically selects the dd item that i happen to be on... it is as if the updatepanel is causing a full page refresh.
i can use the timer_tick event to set label values, and it works like an update panel should....only updating the content inside the updatepanel. it is only when i am trying to choose an item from the dd in the masterpage that a full postback occurs. this creates a problem, because whatever item in the dd i happen to be on when the timer ticks is the one that gets selected. the selectedindexchaged event is supposed to call a full postback, but not the updatepanelupdate caused from the timer tick. my dropdownlist in masterpage
I have a dropdownlist implemented in my masterpage. It has an sql data source from which it loads the values of companies. Depending on which value(company) selected, it shows that value in a label on a different page. The ddl which is in the masterpage is ofc still visible and should display the selected value which it does at the 1st time a value is selected. But when i select another value in the ddl it shows the value which was 1st selected and so on. So it doesn't update or something.
and this is the code i'm using in my Page_load method from the masterpage:
if (Session["Company"] != null) { DropDownListType.SelectedValue = (String)Session["Company"]; }
If I remove this last piece of code from my page_load method it updates the label with value on the redirected page but it resets my ddl to default value instead of keeping it at 4 when value 4 selected.
i have a dropdown list it contains bookid and book name,i have binded it inside the grid view in row databound control,now i want to save the data that requires book id bt during save there will be no access of that book id from drop down that contains inside the grid view control.how it can be solved.
I have a database that tells me what contract is in effect on specific streets but between mile marker values.
For example, Main Street is 10 miles long. Contract ABC123 applies to miles 0 - 4.9, and contract 999555 applies to miles 5-10.
My user will enter the street name and mile value into textboxes, and the results will be displayed in a gridview.
Getting the Street name portion of the query is working fine, it is this mile value that is confusing me.
In my table I have StreetName for the name of the street, and for the mile range of the street the table has BegMile (beginning value) and EndMile (ending value).
How do I get the correct answer back when my user is entering a value between BegMile and EndMile?
In my application, session value automatically set into null.In certain workflow only it will set as null (Normally It's able to access value). Example, at the time of login, I will set session values. While, user deleting some entries from drop down list of specifc page,client script will show message like selected entry deleted. After that, flow point will move to master page. There I have to access session variables. It's getting null value. I tried to debug with Quick watch, at the pageload of master page only value set into null (automatically).
