How to query a SQL database with Dropdown Value Selected as All. Supportgrp is a Dropdown List, if i select All in the Dropdown List all
values from the database should be displayed.
I use the below code currently without All selection:

I would like to alter the query that is run, depending on the selection made by the user in a drop down list on the same page. Would this best be done using a partial page update (AJAX)? Ideally it would be great to have the textbox result change quickly once the drop-down list value has changed, without a full page postback. I would like to change the SQL query to a completely different query if the user selects an option different to the default (page_load value) in the drop-down list. I would then like the newly retrieved result to be displayed in the textbox as before.
My current VB function looks like this:

View 7 RepliesI have two dropdowns in the footertemplate of my gridview inside a usercontrol.
I also have a button "btnADD" inside the footer template. I am using the footertemplate to add a new row to the grid.
What do I do to validate on Button_click event for 'btnAdd' if a value is selected in the dropdown other than "select.." which I dynamically add in rowdatabound event?
I have this javascript function that I wanted to implement, but it gets called in the Page_load event rather than the button click event and gives an error.
The javascript function that I need to call is this: ( I created a method to return a string to use it in regards to RegisterClientScriptBlock, but do not know exactly how to use it)
rotected string BuildValidation()
{
StringBuilder sb = new StringBuilder();
sb.Append("<script type='text/javascript'>");
sb.Append("function ValidateWComp() {");

I'm having trouble figuring out how to display a gridview based on the selection of a drop down list. I manually entered the drop down list items, but in the configure/choose data source I don't understand how you make a relationship between each list item and the corresponding database table you want to show.

i want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view. I go to page 4 to look at some sales there and then switch the month to August 2010 to see sales for that month instead. Here is the problem. When I switch the month, it show August 2010 sales, but stays in page 4 instead of going back/resetting back to page 1 of August 2010 sales.
How do I reset the grid view page back to the first page of August 2010 sales?

View 6 RepliesI am using the following code to bind BusinessID as the DataValueField of the ddlIndustry dropdown. What I want to do is save the selected ID to a different table (Company).

I am trying to bind a record to a textbox using a Dropdown selected index change. I get the error.
Conversion failed when converting the nvarchar value 'DrFirstName DrLastName,Ph.D.' to data type int. is it because I concatenate the name and prefix of the DR into the Dropdown list like this,
Code:
SELECT ID,EmailAddress, DrName + ',' + PreFix AS DrName FROM DrNames
Here is the dropdownlist code that I want to populate the textbox with the emailaddress in the table associated with Dr name and ID.
Code:
Private Sub DropDownList1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles DropDownList1.SelectedIndexChanged
Dim dt As New DataTable()
If DropDownList1.SelectedItem.Text = "OTHER,..." Then
txtRx1.Visible = True
DropDownList1.Visible = False
End If

When I select the Search By dropdown, an additional gridview is created on auto-postback.I will ad a visual and code as soon as this is accepted for review.
View 1 RepliesI am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?
FYI I am using Visual Studio 2010 and SQL/Server
I am using a dataset control and I have 5 dropdown lists in which their content depends on what item is selected in each dropdown list.
I know I can populate the lists with 5 different queries taking the variables from each list but I am thinking there must be a better way.
Is there a way to populate each list with one query that takes the distinct items from each column returned without looping through the entire recordset?
I want to display the selected value from gridview in a dropdownlist.Here I am not getting the Dropdown from Database as it contains two values.After getting the data user can modify the DDL and change the selection.The data type where the values are saved is declared as Bit.

Till here it works fine how do I fill the dropdown from database.Eg Active text is coming from Database,so DDL should show Active along with Inactive value.
I try to set the selection in the radiobuttonlist accordingly to data retrieved from the database.
This is not working (the mydata.gender contains "Mail")

View 1 RepliesI would like the user to select an item from a drop down list. Next to the drop down is a textbox or label control. From the ddl selection I would like to populate the textbox or label from a database with a corresponding field from the database the dropdownlist was populated from. On selectindexchange event I can populate the textbox with the Unique id from the value, but I need to input a different field into the textbox. Can I use some sort of variable to assign the Textbox.Text = ?
