I am experimenting with 3 dropdowns bound to 3 different datasources. I want the contents in each dropdown depending on what is selected from the above dropdown and the datasource queries reflect this.
However, the second dropdown does not load with the relevant data when I select a value from the first dropdown (stays blank). Must I still provide an event handler and how do I combine this with the sqldatasource?
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.
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 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.....
Is it possible to display two column values from a SQL database in to one DDL? I have been trying to write a SQL query, where in I select two fields to be displayed in the DDL but when I run the application it only displays one. Not sure why. Here is my code below:
I have a Detailsview grid with an SqlDatasource, this DVG is only going to be used to insert records. The primary purpose of the DS is to populate a DDL control in the insertItem Template that I created my code is this:
[Code]....
The DDL control populates correctly, but when I try to modify the INSERTCommand property in my DS, I try to assign the value to my parameters "TesterID" and "TesterDate" but the only options for controls to pick from, is the DGV but not the DDL in it. I assume it has to do with the InsertItem template but even if I reset it I still cannot pick the textbox as a control that would give the value to my parameters.
I did find a workaroun by build a public method and calling it in the onclick event of the insert button but looks like I have to create another connection to the database which to me seems unnecessary since I already have a DS and everything. how can I do this without having to use my method. here is my method just in case.
I have a table that has 3 fields (Individual-Id, LastName, and FirstName). I want to create a drop down table that displays both the FirstName and the LastName (example: Smith, John). The field Individual-Id is the 'value' field.
I Have the gridview control with 2 dropdown list and 2 text boxes,When the textbox chnaged event happen 1 row will create and the dropdown back to initial values( its not retaining the selected values),I am binding the control after text changed method,Is there any properties needs to be set or any other way we can retain the values in postbacks?
I am fairly new to ASP.Net and web programming in general and I am having issues trying to add values from a dropdown list in my gridview to another table.
Here is my scenario. I have 2 tables in my SQL Express DB. When editing the values of table2 in a gridview, I would like to show some data from table1 in a dropdown so users can select a value from table 1 and enter that value in table 2.
I have the Gridview setup to show table2 data.
I created a field template and inserted my dropdown list and linked it to my table1 data source.
When I run my web form, I can click to edit one of the fields in the gridview, and my dropdown list correctly displays the data from table 1, but when I try to update the table2 with the dropdown value, it doesn't correctly update. The row in table2 never updates.
posting the dropdown value from table 1 into the appropriate field in table2..
Again, I am new to this and have been following the tutorials etc on this site, but can't find one pertaining to this topic.
I have a dropdown control that has a list of names in it called PlayerNameDropDownList_Insert and a textBox called PlayerName.
When I select a name from the dropdown it populates the textbox correctly.However, when the page opens the first name is selected in the dropdown but nothing in the textbox. How can I get the textbox to populate with the value of the dropdown at pageload?
