When using a split window, the splitter will begin with the distance you provide it.
However it reacts based on changes to the forms in each panel. Adding a larger control to the top panel can push down the splitter as well as resizing the window. (Resize will cause it to try and maintain some type of relational sizing to the original size you created at design time) I found this out when building an 'Outlook-like' application and the button panel kept changing sizes.
I fixed the problem by hooking into the Resize event. Every time the form containing the split windows did a resize, I reset the splitter distance to the preferred location.

Thank you.
I changed setting to hold persent and added following code to resize method. Every time I re-open the form, Splitter moves up by a number of pixels. So top area becomes smaller and smaller until reaches to minimum height.
How to fix this ?
I have simple form containing ToolStrip and single horizontal splitter with DockStyle set to Fill. Top spitter are contains DataGridView and nbottom area contains multiline TextBox both with DockStyle set to Fill.
protected override void OnResize(EventArgs e) {<br />
if (Settings != null && Settings.SplitterDistance > 0m &&<br />
Settings.SplitterDistance < 100m) splitContainer1.SplitterDistance = (int)(Settings.SplitterDistance * (decimal)splitContainer1.Height / 100m);<br />
<br />
base.OnResize(e);<br />
}

In this example, you are computing the distance instead of defining a specific distance. So what is happening with this:
protected override void OnResize(EventArgs 3)
{
if ( Settings != null && Settings.SplitterDistance >0m && settings.SplitterDistance < 100m)
splitContainer1.SplitterDistance = ....your math
base.OnResize(e);
}
First you say you are only going to calculate a splitter distance if the distance is less than 100m.
You then compute by multiplying the distance by the height/100m. Your height is just a teensy bit smaller than your splitter distance.
So your height/100m will be a decimal since the height of splitcontainer1.Height being less than 100 causes the splitter distance to be less than 100. Not only will it be a decimal but it will be a decimal less than 1.
So now when you compute the splitter distance you are shrinking the distance by whatever the decimal amount is. So if my height is 50 then you've just moved in the splitter distance by 50%. ( distance * 50/100 -OR - distance * .50 )
Now you do something causing another resize event. Assuming you did not move the splitter itself then you are guaranteed of the fact that you are less than 100m. So when you catch that event you will move it once again.....only a smaller percentage this time. But each time you move it you will make it smaller and smaller because you are mulitplying it by a number smaller than 1.
Either do one of two things: leave it be where it ends up -- or determine a good place to have it in a fixed location. So maybe having it 100 pixels out is good. Then set the splitter distance to 100 every time you get a resize (unless the entire window is less than that).

No. Settings.SplitterDistance holds now upper pane height persent in range 0 .. 100% . I changed its name to SplitterDistancePercent.
Now you do something causing another resize event.
I do'nt understand this. Why you think that changing Splitcontainer SplitterDistance causes form resize event ?
leave it be where it ends up
My issue is that it does not remain in same place but moves up by some pixels every time form is re-opened.
determine a good place to have it in a fixed location
I need to allow end user to determine the good place by moving splitter by mouse at runtime. I save form splitter distance percent in form close event:
protected override void OnFormClosing(FormClosingEventArgs e) {<br />
Settings.SplitterDistancePercent = splitContainer1.SplitterDistance * 100m / splitContainer1.Height;<br />
SaveSettings();<br />
base.OnFormClosing(e);<br />
}
I want that splitter remain in this place when form is opened again.
It is not possible to add fixed place constant to code.

i m using the numeric validation for mobile...
if (txt_mob.Text != "")
{
Regex n = new Regex(@"(?<name>[0-9]|- |\+){10,20}");
Match v = n.Match(txt_mob.Text);
if (!v.Success || txt_mob.Text.Length > 20 || txt_mob.Text.Length < 10)
{
MessageBox.Show("Only digits '+' & '-' are allowed in Mobile and its size should be between 10 and 20 characters");
txt_mob.Focus();
}
}
its working ..but it takes 10 characters numeric and after that it is also accepting non-numeric characters please help

damn... why dont you use KeyPress event and check e.KeyChar, if its numeric then go ahead else show message, something like this
if (char.IsNumeric(e.KeyChar))
{
}
else
{

Looks like you need assert position at the start and end. Try this
^(?<name>[0-9]|- |\+){10,20}$
|
|
|
|
|
Regex n = new Regex(@"^(?[0-9]|- |\+){10,20}$");...throwing this error..parsing "^(?[0-9]|- |\+){10,20}$" - Unrecognized grouping construct...please help

Make sure your string is well-formed. It's working at my end.

thank you very much..its working

An alternative method would be to try and use Double.TryParse, or Int32.TryParse. Something like that. If they fail to conevrt the string into a number then you have non-numeric characters in the text box.

Hi there.
I have saved an MS word file to my database.
I retrieve the following fields when accessing the DB:
byte[],
filename,
extension
I now want to, in code behind, open an "Download to" window, where i can save the file on my local machine.
P.S i dont just save word files... i want to save any type of file.
Can anyone help me with the problem?

Did you look at Response.WriteFile?

no, but how would you integrate the fields with Response.WriteFile
|
|
|
|
|
Basically, you set the header to say you're downloading the file, and then stuff the bytes of the file into there.
You should ask ASP.NET questions in the ASP.NET forum BTW.

it is a bit unclear, what header are you talking about?
"you set the header to say you're downloading the file".
could you give me an example of this?
Sorry about the "Not being in an asp forum"..

thanks for the example.
one last question, because the file has no path, only byte[], how would i populate the FileInfo, so that i can use that information in the headers and WriteFile?
|
|
|
|

Response.ContentType="application/zip";
Response.AddHeader( "content-disposition","attachment; filename="+filename);
Response.BinaryWrite(byteArray);
Response.End();
That will cause whatever you want, to be written to the browser so the user downloads it.

Hello everybody,
I have created a javascript (ajax) making a request to the server for save the infomation i have passed as arguments with the request. like this
var args = "id=" + ID + "&name=" + Name + "&sex=" + Sex + "&age=" + Age;
xmlHttp.open("POST","SaveInfo.aspx",true);
xmlHttp.onreadystatechange = function theStateChanged()
{
if (xmlHttp.readyState==4 && xmlHttp.status==200)
{
alert("Successfully Saved");
}
}
xmlHttp.Send(args);
these are OK. but i want to catch the args from my asp.net webpage.
When i am using GET method for request, i am sending arguments by query string, and in .net page i can access that using Response.QuerySting["key1"].ToString(); But this time i am getting problem. how can i access the arguments passed. Please help me.
Thanks in advance for help.

Please don't cross post.
The httpRequest object has properties like responseText that you can use to get data back from the server.
