Web Forms :: How To Clear DropDownList Selected Item
Apr 22, 2013
I have dropdownlist in my page
In Page_load page I wrote below code
if (!IsPostBack) {
DDL1.Items.Insert(0, new ListItem("select city", "0"));
DDL2.Items.Insert(0, new ListItem("select region", "0"));
DdlDistrict.Items.Insert(0, new ListItem("select district", "0"));
}
And in this page I have btnInsert that when users click on it, it insert data in database
I want when users click on button all textboxs text be clear and all DDL selected Item clear so I set below code in btnInsert event
I have the problem with dropdownlist value inside gridview.my problem is i have textbox,button with two dropdownlists, dropdownlists are inside gridview.Two dropdownlists are one is ddlcountry and another one is ddlstates. if i select country from ddlcountry , country related states comes in ddlstates. after entering first record value in textbox then button click textbox value is shown in gridview with two dropdown lists dropdown list, after selecting one dropdownlist country and states, i enter second record value and button click then only country selected value visible ddlstates selectedvalue not visible in first record in gridview...
Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load
DDL1.Items.Insert(0, new ListItem("select city", "0"));
And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.
I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.
Database Table: This data has been imported using Link to SQL
I have items in a sql table that i populate a dropdown list with. so on page load the items are sent to dropdown list. I have a button on the page with the dropdown list that onclick it launches another page that allows more items to be added to the database table.
What I want to do is to refresh/update the list of items in the dropdown list when the second page is closed. In addition the last item added to the table will be the selected item in the drop down list.
I am inserting a new states in the table from dropdown list , the dropdown list has new in the list, clicking on new gets me a pop up which takes the new state and inserts in a table. My requirement is I want to get the last inserted state in the dropdownlist and its id to be selected as soon as insertion is done.
The second function is to insert the contact details where i have countryid,stateid,cityid
protected void stateSave(object sender, EventArgs e) { using (SqlConnection conn = new SqlConnection(cs)) { SqlCommand cmd = new SqlCommand("newStates", conn); cmd.CommandType = CommandType.StoredProcedure; SqlParameter outparm = new SqlParameter("@stateID", SqlDbType.Int);
1- ddlzone1 2- ddldistrict1 and one button (search)
At first I select item from ddlzone1 click on search button according to below SP it search on database and show result...
ALTER procedure [dbo].[GetCustomersPageWise] @PageIndex INT = 1 ,@PageSize INT = 5 ,@RecordCount INT OUTPUT ,@Region nvarchar(10) ,@District nvarchar(20)
[Code] ...
Now I want when users select item from ddlzone1 after that if they select item from ddldistict1 according to their selected item from ddlzone1 and ddldistrict1 it search in table and show result
Now how I can change my SP
I changed below code in SP but it didn't work
WHERE ([HOuse_info].Region = @Region or @Region='0') or ([House_Info] .District=@District or @District='0') SELECT @RecordCount = COUNT(*)
i have dropdown list in my page that bind it from database
BindDropDownList(DDL3, "Guidcenter", "Centername", "ID"); DDL3.Items.Insert(0, new ListItem(" select all", "0"));
here when users don't select any thing from dropdown list in data base insert 'select all' text but i want if users don't select any thing from DDL in database insert NULL.
I have a bunch of dropdowns in a gridview and I populate them through a datasource.On the databound event i need to change the selected item to the actual selected value from db.

now my problem is :
when i click item from menubar in index.aspx when it go to state.aspx it doesn't show any thing in gridview.
i want at first when users go to state.aspx page they can see all data in gridview after that they select item from DDL and see result according to their selected item

I have a DropDownList in a template column of a GridView control. The GridView is bound to a list of objects. Each object has a property of type int which corresponds to a value in one of the DropDownLists ListItems. I could set the selected item programatically by adding a DataBind event to the drop down, but I'm wondering if there's a way to set the selected item by using a code block in the aspx markup.
