Forms Data Controls :: Dropdown Is Not Loading With Newly Added Values From DB?
Apr 1, 2010
In my asp.net page i have one dropdown and its vales are loading from db.
new values for the dropdown we can add using a popup also for the popup i am using this code
[Code]....
once the data is added then i am refreshing the parent page using javascript and reloading the dropdown using the below code . and values are from db.
[Code]....
here in AllUSersByRole i am getting the newly added value from the db after that i am binding the value to dropdown and the new added value is not showing all the other values are present.
I am working on a web form using VS 2010. The controls I've added previously to this form will show in the drop down list in code behind and are available to add events too. However any new controls I've added for last week or so are not visible in the list. I cannot access their events. I have scoured the forums and tried everything I can think of, nothing works.
I have a grid which uses an objectdatasource. Data is correctly retrieved using the select method. When I add a new record a new row appears in the grid and I can enter my data. I do have access to the row on saving as I can access this new row from the Grid's insert method - using the GridRowEventArg like so (this is using an Obout grid control but the principle can be seen):
I am opening a new window on clicking the button using folowing code
[Code]....
In a newly open window their is a form. on clicking the Save button i am cloging the clild window and refereshing the parent page using below mention code
Page.ClientScript.RegisterStartupScript(this.GetType(), "close", "<script language=javascript>window.opener.location.reload(true);self.close();</script>"); Upto here everything is fine. but the newly added data in the child window is not reflecting in the parent page.
I have a FileSystem based asp.net 2.0 app that uses Sql Server 2005 Express database.
I have only one dataset for this app with only 4 tables. After i have completed it to a part, a co-worker have added some Classes to it, which are not in same namespace of myBLL classes.
Then i tried added a new table to the dataset. It like all other tables in that dataset uses SQL Statements to access and manage data.
The problem started after i added that new table. I cannot access it from code. I can access all previous TableAdapters but not this new one.
Recently i am working in VS2008 installed in windows xp SP2. In the toolbox i added a new tab and added some third party controls in the toolbox, by using "Choose Item" dialog.. I also added Ajax ToolKit to the tool box. It worked fine and i could drag n drop controls.
But then if i restart VS2008, all the tabs i created and controls in it goes off and disappears ncluding Ajax Toolkit. Each time i restart it, I have to have add those controls newly?
Is this a Bug?? or Is there any solution for this?
I have a DetailsView using a LinqDataSource. I have it connected to DropDown so the user can select a record to edit. This configuration works. However when I add a record after I enter the data and press insert link the DetailsView reverts to another record. How can I make the DetailsView stay on the newly added record?
I have come across an issue with my DataGrid loading several drop downs. The idea is I initially wanted it to load the drop down on the OnClick event of my DataGrid, however I realised there is no OnClick event (I come from a windows form development environment). Considering the time it may take to load this drop down may be extensive (which is why I wanted this drop down to be loaded individually, only when user clicks it) I came up with another idea of wrapping the Grid in an ASP Update Panel so I load all the drop downs in the PageLoad() event.
My question is, is this the correct thing to do? If I am loading 100 drop downs wouldn't it be better to load the drop down objects indivdually as opposed to all at the same time? How do I load a drop down based on the OnClick event of a DataGrid?
Tried using the OnSelectedIndexChanged() event but doesn't seem to fire the event after I click on the row. Ideally I want something like when the user clicks on a row, I want to load the drop down associated with that row. Is this possible?

Ive been strugglng with this one problem for a while now. I have an application as: SelectCommand="SELECT [CategoryID], [Name], [UserId] FROM [Categories] WHERE ([UserId] = @UserId) ORDER BY [Name]"> <SelectParameters> <asp:QueryStringParameter Name="CategoryID" QueryStringField="ID" /> </SelectParameters> [code]....
the dropdown list control will populate values from the database but when i live those 2, it won't populate any value from the database. When i remove only the <asp:QueryStringParameter Name="CategoryID" QueryStringField="ID" /> </SelectParameters> and live ([UserId] = @UserId), i get the error : Must declare the scalar variable "@UserId".
I'm populating a dropdown box bound to an sqldatasource. From the sqldatasource, I'm retrieving locationID,locationType and LocationName.
The locationName is displayed in the dropdown. The selected values is set to, "locationID'. Based on the 'LocationID' the user is directed to a new page.
However, I need to pass the "locationID" and also the "LocationTYpe" values for the selected Name, so the sure can be directed to a specific page..how do I get BOTH values, 'locationID' and 'LocationType' when the user selects 'Location NAme' from drop down.
when testing my query in the grid configuration wizard it works fine, but when i run the page it does not.
first - i select values from my cascading drop down list then enter values for two textbox (dates). then when i hit the button to populate my grid nothing is return back.
when i click the dropdown list it is postbacking(since i made auto postback=true). on that time i am unable to get the selected value from dropdown list.
i have 4 text boxes and 2 dropdowns are there when ever i fill it all values should place in grid view., after entering of 5 or 6 records, i click on SAVE button then ,i want to save those values in to Data Base ,which are at Grid view.....

So that fields are visible in the Fields object section from where i can drag and drop the fields on the report and display it. But now as they want more fields i have written two select statements for displaying required fields. But these newly added fields are not visible in the Fields object section in the Crystal Reports.
