I have a DropDownList being filled from a data base. Now, when I select the drop down arrow, is there a way to set the size of how many lines to show initially ?
Like: DropDownList2.Attributes.Add("Size", "16")
I cannot find an event when clicking the drop down arrow.
I have read many pages on detecting mobile phones but my question is for setting the screen size for this. I can easily made the screen the same size as my mobile phone but on some devices you still have to zoom in to see it. Is this mainly on the device side that needs to be set? Is there any way to tell the device to show the page zoomed in?
View 10 RepliesI am using PageMethods to send a few parameters to a webmethod in my codebehind. The method runs a stored procedure and uses the results to build a string that I am returning from the method.
Everything works fine until I try to include too many records in my results..
Once the results I am trying to return hit about 70K, the pagemethod times out even though it is taking about 1 second to process the results.
Is there a buffer limit or limit on the size or results returned from a pagemethod and if so, where can this be set or changed?
Is there a setting in the web.config somewhere to handle pagemethod buffer size?

View 1 Repliescan you set the the image size of this control with css?
<img style="border-width: 0px;" alt="Test image" src="userdata/1/uploadedimage/database%20entry.jpg">
Not sure if theres a way I can assign a certain size to this either by css or by Jquery? Or if I can do it directly in my C# code using something like img.Style?
EDIT:
Just to clarify my css is like so:
div .test
{
width:90%;
z-index:1;
padding:27.5px;
border-top: thin solid #736F6E;

I have a Dress Version Table with Colums UK, EU, USA.
Also a Dress Size table which has a VersionId Column corresponding to the Version Table
On my aspx, i have two drop down lists. DD1 is binded to an objectdatasource which
has a select Method to the DAL and retrives the 3 Verions.
DD2 has Get DressSize by Version Method with a Select Parameter which is the DD1 selected Value.
I have wrapped the above in an update panel and the full code is below.
This works but I wonder if there is a better way of doing this?? I also have a probem in that the Dropdowns are in a panel that is within a modal pop up extender. When the dropdowns post back the whole panel disappears. Not sure why??

I have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.
Then there is a second ddl.
If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2.
If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).
Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:
Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:dropdownlist id="EffectiveDateDropDown" runat="server"></asp:dropdownlist>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="QuoteType"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
It wants to do something when the selected index is changed? This exists in the code-behind, but I set a breakpoint and never hit it:
Code:
protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
}
catch (Exception err)
{
this.PublishError(err);
}
}
I am trying to increase the size of file upload for my ASP.NET app.. (Windows 2008 Enterprise + IIS 7)

<requestLimits maxAllowedContentLength="100000000" />
</requestFiltering>

I just installed Safari, Chrome, Opera and Firefox on my machine that runs VS 2008. Prior to this, IE was the browser used whenever I would run a project to test. Now it is executing Chrome, even though I said it's not the default browser.
Does anyone know how to change this setting in VS 2008 or wherever else it may be required?
<%= Html.DropDownList("couriers", Model.Couriers, "--Select--")%>

Now its value rendered is ""
how can i set its value to "0"
I have a text box into which the user types a string of characters. When they have completed this search string they click on a button which then displays the number of matches found and populates a DropDownList control with them. The user has to then drop down the control to see the matches, but it would be much slicker to drop down the control automatically for them, especially as they sometimes don't notice there is more than one match and, therefore, select the wrong one.
I have written a website and let the user upload their photo. It also resizes the picture to 400 x 400 and crops automatically to the center part of the picture. All of this works good but each file is about 355K each for JPG and PNG file formats. I just tried GIF and it is 49K but the picture is grainy when saved this way. Is there any way I can get the picture to a smaller file size with keeping it at 400 x 400? I really thought PNG would be the way to go and was surprised by it being the same as jpg. I don't want to lower the quality either for JPG files.

I binded the dropdown from the table Languages, now it shows all the languages:
ViewData("Languages") =
New SelectList(objLang,
"SysLanguageID",
"LanguageName")
Now when I click the edit then the dropdown should show the selectedvalue based on the languageId that is in stored in the Preferences table under the user.If i give the third parameter as the selectedvalue it is showing the selected value but it is not showing the other languages.
I have a databound dropdownlist on a page, where in the page_load I set the selectedValue (inside a 'not isPostBack').
Although the page displays fine and shows the correct item as selected.. inside the page_load if I try and get the selectedValue() and display it to the screen, I always get null... selectedIndex is -1.
I have a button, which when clicked refers to this ddl's selectedValue, and here it pulls through the the expected result.. so how come I can't see it immediately after setting it, while still in page_load?
edit: the code..
ddl declaration
<asp:DropDownList runat="server" ID="dlCountryList" DataSourceID="dsCountryList"
DataValueField="countrylistid" DataTextField="description">
</asp:DropDownList>
and the page_load
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
dlCountryList.SelectedValue = "GR"
Response.Write("*" + CStr(dlCountryList.SelectedIndex) + "*")
End Sub
i have a dropdown list and what happens is that when i click on the dropdown button the list appears under other controls and it pops upwards. If it pops downwards and is non transparent then it would be visible .how is this achievable ?
