I have to generate multiple dropdownlists on clientclick. That is new dropdownlists on every client click.
I placed a button and wrote code on click event. protected void addReq1_Click(object sender, ImageClickEventArgs e)
{
DropDownList oDdl = new DropDownList();
oDdl.ID = "ddlReq" + (++i).ToString();
oDdl.DataSourceID = "DSUsers";
oDdl.DataTextField = "UName";
oDdl.DataValueField = "UName";
HtmlTableCell tc0 = new HtmlTableCell();
HtmlTableCell tc1 = new HtmlTableCell();
HtmlTableCell tc2 = new HtmlTableCell();
HtmlTableCell tc3 = new HtmlTableCell();
tc2.Controls.Add(oDdl);
HtmlTableRow tr = new HtmlTableRow();
tr.Cells.Add(tc0);
tr.Cells.Add(tc1);
tr.Cells.Add(tc2);
tr.Cells.Add(tc3);
search2.Rows.Add(tr);
}
Here "DSUsers" is SqlDataSource. "i" is static variable. "serarch2" is html table with runat server tag The problem is only one control is getting rendred, after that on every additional click same DropDownList is getting replaced. No new DropDownList is added to the page.
I want to assign same datasource to multiple DropDownLists in a form, when the page loads, only the first drop down list has filled the content of datasource, others are empty, what's the missing point? Here are the codes;
I have an SqlDataSource at the moment, which I want to be able to be filtered using 3 DropDownList's. Basically, each DropDownList contains values for a certain column on the table, so when they choose one of the values, the SqlDataSource only shows values with that value in the relevant column.
So my table is somewhat like this:
ID (primary key) ManufacturerID ItemTypeID UnitTypeID
My filter expression for the datasource is currently like this, but it doesn't seem to work unless all 3 boxes have a value selected, which is not ideal. Any ideas guys? My filterexpression is below:
ItemTypeID = {0} OR ManufacturerID = {1} OR UnitTypeID = {2} OR (ItemTypeID = {0} AND ManufacturerID = {1}) OR (ItemTypeID = {1} AND UnitTypeID = {2}) OR (ManufacturerID = {1} AND UnitTypeID = {2}) OR (ItemTypeID = {0} AND ManufacturerID = {1} AND UnitTypeID = {2})
I have the following code which toggles the visibility of one of a pair of DropDownLists based on the selected radio button. This code works but my problem is that I have several sets of controls just like this on a single form. How can I use a single JavaScript Toggle() function, irrespective of the ID of the RadioButtonList that triggered it?
function Toggle() { var list = document.getElementById("produceDDL"); var inputs = list.getElementsByTagName("input"); var selected; for (var i = 0; i < inputs.length; i++) { if (inputs[i].checked) { selected = inputs[i]; break; } } if (selected.value == 'Vegetables') { div1.style.display = 'none'; div2.style.display = 'block'; } else { div1.style.display = 'block'; div2.style.display = 'none'; } } <asp:radiobuttonlist ID="produceDDL" OnClick="javascript:Toggle();" RepeatDirection="Horizontal" runat="server"> <asp:ListItem Selected="True">Fruit</asp:ListItem> <asp:ListItem>Vegetables</asp:ListItem> </asp:radiobuttonlist> <div id="div1"> <asp:DropDownList ID="fruitDDL" Width="120" runat="server"> <asp:ListItem>Select</asp:ListItem> <asp:ListItem>Apples</asp:ListItem> <asp:ListItem>Oranges</asp:ListItem> </asp:DropDownList> </div> <div id="div2" style="display:none;"> <asp:DropDownList ID="vegDDL" Width="120" runat="server"> <asp:ListItem>Select</asp:ListItem> <asp:ListItem>Onions</asp:ListItem> <asp:ListItem>Potatoes</asp:ListItem> </asp:DropDownList> </div>
I'm attempting to hook up multiple DropDownLists to a single SQLDataSource, but I want the SQLDataSource to return different rows depending on which DropDownList it is populating.
Say I have a table full of names (we'll call it TABLE_NAMES):
[code]....
....and I have two dropdown lists, one with a list of person names and one with a list of dog names.
Is there a way to link up each of these dropdown lists to a single SQLDataSource and use the SelectParameter to differentiate between which records I want returned for each dropdown list?
To make matters worse, these dropdown lists will appear within a GridView control....so there will be multiple instances of each dropdown list depending on how many rows there are in the GridView.
hope you guys are doing well! I have a question and no answer yet how to do it. Right now i can have 1 dropdownlist and when i press on my search button its show the result of the query the user ask
but how to do it with two seperates dropdownlist ? isnt it with inner join ? also if the value is null what to do ?
I hope somebody can guide me to overcome below challenge.
My form has three dropdownlist controls and one listview. Everything works fine if I don't try to pass multiple querystrings to get different URL on the same page. But challenge comes when I try to pass multiple querystrings to show different URL's for SEO.
Following are the ID's:
1. DropDownList1= Country
2. DropDownList2= State
3. DropDownList3= City
4. Listview1= Resturants (I am not including Code .....yet)
With my code DropDownList1 holds the state and passes the value to URL OK .When I try to select different value in DropDownList2 or DropDownList3 are able to pass the vaule to URL but in the form they stay on the first item and doesn't change and so does Listview1.
I'm wondering how I can make one dropdownlist affect another one.. For example...You select your country from a drop down list of countries. On selecting it, another dropdown list becomes visible and displays the states of your country. I'm taking this data from a database, so it merely has to link to a different table for each country selected.
Also, I want the option of being able to add a 'state' to the database from the webform by typing whatever its called into the combobox so that future users will see that option.
i need to generate multiple pdf files based on input parameters using ssrs. Suppose there are 1000 branches then it should generate 1000 pdf files one for each branch data. how can i achieve this using Sql Server 2005 and .net framework 1.1 or 3.5.
I have a situation where I need to generate multiple sets of radio buttons. These radio buttons display One to Many relationship data.
I know how to get it to work with a workaround that I used back in Classic ASP days ... in which I essentially just spit out the HTML dynamically and keep track of my controls using systematic IDs. Which is nothing more then an Primary Key appended to a string constant i.e. String.Format("Dynamic_{0}", myChildRecordPKValue) so my HTML looks like this:
[Code]....
Note that I am using a javascript function which updates a hidden field with the selected value (Each parent record has a corresponding hidden field). So after making selection user will hit the submit button and I get my values using Request.Form[myHiddenField1] and so on ...
I want to generate crystal report in pdf format. I had done the same thing by passing one parameter. But this time I want to pass 10 parameter. I followed the same thing what I did for passing one parameter.
But now I got the Error Message "Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack."
I have a page where i enter the number of members i need to add now suppose i chose 3 so on next page i have get a display like member1 enter details(name, address, phone etc) just below that again member2 enter details(name, address, phone etc) and member3 enter details(name, address, phone etc)in short the no of forms displayed in a page depends on the no of member an user want to add and on submitting the data's of 3(no. provided by the user)member has to be inserted. As i am a rookie to asp.net its hard for me to imagine the logic and implementing them, what to do about tose textfied id's? how to generate the id's and how to separate the codes in .cs and .aspx etc
I have made an application to upload an image and a textbox to give that image a caption. So, there's a privilege to upload only one image and caption at one time.
Now, I want that I am able to upload multiple images together and also can give caption to all images to.
So, there should be a ADD button to generate multiple filupload control and textbox together.

I'm using a code I got from CodeProject [URL] about a validator that can monitor 3 form controls. I pasted it to my site, changed it to suite my parameters but seem to encounter a situation that can't satisfy my desire: Instead of making sure that all the 3 DropDownLists are filled without their default value, the validator cares only if at least one has been filled, and if so, he can call it a day. look at this code at tell me what am I doing wrong?
I have created a label and a dropdownlist. The label has the dropdownlist as associated id.If I click on the label and then uses the mouse up or down the dropdownlist creates a postback for each click. This is quite anoying and doesn't happen if you click on the dropdownlist and uses key-up or key-down, or if you uses another browser than IE.Is it possibel to fix this, so you can use key-up and key-down without causing a postback, and first on the enter-key creates the postback (as it does if you click on the dropdownlist and not label)?
I am trying to use two DropDownLists (Cities, Categories) in a PartialView that will be used in MasterPage, meaning they will be visble all the time.
I tried to load them in HomeCOntroller, but that didn't work. I got an Exception.
I read something about making a baseController that the other controllers will inherit from, I have tried that, kind of, but I guess i'm doing something wrong.
This is the only code I got today:
Masterpage
[Code]....
PartialView (SearchForm.ascx)
[Code]....
Two question:
Where and how to load the DropDownLists is the problem. I have tried to load it in the HomeController, but when go to another page then it says that the DDLs is empty and I get a Excecption. Why do I have to use two forms for the ActionMethod to trigger ?
On my webform, I have 3 dropdownlists with datasource to SQL. Through dropdownlists, I want the user to fill the controls, so I can get his location. One for his area, subarea, town or village. Actually the values appears great but I dont like when my page loads, the ddl fills with default values and second when I change, lets say the first ddl, it also full fills the rest with the first default values. All I want to do is, load my page with empty values, assign a value at first ddl, the second remains empty til I click on it and select a value and so on.. here is the code i use
HTML Code: <div id="CreateAccountDiv" style="padding-top:10px"> <%--Label and Textbox for company--%> <div><asp:Label ID="lblComp" runat="server" Text="επωνυμία επιχείρησης" CssClass="sizeLabel" ForeColor="black"></asp:Label></div> <div><asp:TextBox style="width:250px;font-size:10pt" ID="txtComp" runat="server" CssClass="sizeText transparent" ValidationGroup="form">
I have a dropdownlist on my page which has autopostback set to true. On postback I populate a runat server div with a bunch of other DropDownLists. I then have a button which does another postback to save the selections. Because the second set of dropdownlists are dynamically generated I cannot for the life of me figure out how to get their selected values?
1st DropDownList
[Code]....
Then when I try get the dropdownlists using a foreach on the div that I added the control to it does not work. They are populating fine, its just on the button click. I have tried EnableViewState = true on the dropdownlists and my code is correct because if I code them into the aspx then it works, its something to do with the state.
I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists.
For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List.
i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database.
