Client script means that page will not get post back to the server and on the client machine itself it will do the process.

Hello, Friends
I'm binding some data in my GridView using ObjectDataSouce. I need too, specify some SelectParameters what are stored in ViewState, but in the "Parameter Collection Editor Dialog", the "Parameter Source" option shows only: Cookie, Control, Form, Profile, QueryString, Session
I wish bind to some value in ViewState. How not appears the option "ViewState", I need place my values in some HiddenField control to bind...
Someone knows how I do to bind to ViewState?
Regards
Fabio

Hi there,
There's no such a ViewState parameter existing, but there are two work-around options come to mind that you may consider:
+ Use the general Parameter for the select parameter, and create an event handler for the Selecting event. In the handler, you can populate the select parameter value from the ViewState, then add it to the InputParameters collection.
+ Develop your own custom parameter, say ViewStateParameter, which inherits from the base class Parameter. In the custom class, you at least override the protected method Evaluate to populate the ViewState and return the value. You also should remember that the ViewState is a protected property of the Control class, so if you want to access the ViewState of the control, for example the ViewState of the Page instance, from the outside of the control, you may consider using the reflection.

Perfect explanation! Thank you very much, I will do and maybe I place this custom parameter source here in CodeProject

Hi,
what should be straight forward seems to be causing me a nightmare. Basically, I am reading a simple XML file into a dataset and then binding the dataset to a datalist. The XML contains links to images. Within my datalist is an image holder who's URL binds to what is stored in my XML file.
Here's the problem, my webpage shows some of the images but not others even though I know all the images exist. What's even stranger is when I press the refresh button some pictures that didn't display before now display! Can anyone help? is there a limit to the datalist in the amount it can store and display??
Thanks in advance

Hi there. Which browser are you using for testing? Do you have this problem with non-Microsoft browsers like FF?
|
|
|
|
|
I was using IE for testing. Just tried Firefox and although it took a while to load all the images, they all loaded. Do you think the problem could be to do with the file size of the images? They are on average 1mb.

I think you've misunderstood the technology somewhere.
If you want to create an applictation to send emails once or twice a week, why not create console application that the task scheduler can launch in the background for you?

Please don't cross post.
Please write a useful subject.

It might be possible, but it would be quite a detour, and not a very stable solution.
Do as Colin Angus Mackay suggests and create a console application instead or a web page.

Hi all,
I have developed a custom pager control, which has been inherited from WebControl, IPostBackDataHandler. Function of the control is to render a pager layout ( page numbers, next, prev, buttons ) and raise an event on the server when page change in UI.
Problem is what when i place any validator control which are validate on server only are raising validation on custom pager control's post back.
code preview
PreRender(){
}
Render(){
}
LoadPostData(){
}
RaisePostDataChangedEvent(){
}
if anybody has resolution of this problem, please guide me, i will be very thankful to all of you.
Confidence comes not from always being right, but from not fearing to be wrong.
Mihir..

Do you mean when your custom pager control is working, it causes the validators on the web page to work at the server side? If so, you can try to make your control implement the IPostBackEventHandler inferface, and simply leave the implementation of the RaisePostBackEvent method empty.

I want brief info about editable datagrid
|
|
|
|
|
|
I will have multiple datagrids on a page. Each data grid will be the same in structure, but seperate from the others due to user requirements of collabsibility, totalling, etc. Now the database will determine how many datagrids I will need to display. in addition to the datagrids I need to display a bunch of descriptive text for each datagrid

Hi,
The contents of my asp.net page get all jumbled up when I view it using Firefox! I heard that there is an article here at code project that dealt this problem but I couldnt find it. Can any1 help me out here !

I guess it's rather an HTML mismatch.. as you're HTML is not fully W3C compliant..
Firefox interpretes things a wrong way. Another local forum here had the same problem, and it was a too much..
Just a thought,

 The problem is just related to the uploading file.
Let me explain.
I have grid in which i place the file upload control.Now when i pick up the file from my system(LocalHost) to the system connected to my network i take the path with the file name and bind with the lable placed in grid on insert command.
Now, When i clicked on save button which is placed on page.
It produces an exception some thing like that "remote system is locked"
if i used the file.copy("Path form remote system","path on server").
But it will copy file if i pick up the file from same system.
Now, When i swiched over to FSO and try to copy file from remote file to the server than it will produce the another exception some thing like "Bad user and Password to access the remote file"
Please help me out it's very urgent.
Any kind of help appreciated.
thanks

Hi
My boss asked me to develop an application where it uses datagrid and left most corner I will have "+" and "-" image buttons. On click of "+", a blank record need to be added into datagrid, so that user can insert a new record. Onclick of "-", it should delete the particular record.
Well I implemented the same. But I used Static datatable to insert new record, so that the value will persist across post backs. Everything worked fine, as soon I started testing I found a big error.
While two persons starts working in same page from different PCs, other person's insertions are visible to the first person. I understood its because of static. The static datatable is being shared across the users!!.
But I gone so long that I can not think of going back now. I have done around 15 pages in the same way!!!, so going backward I can not even imagine.
Is there any alternative?, instead of using static datatable, can I use any other alternative?
below is my code snippet
//Declared as class variable
static DataTable dt;
//// When user clicks "+" or "-" button in datagrid
private void dgGoals_ItemCommand(object source,System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
//Each row in datagrid will have + and - imagebuttons at left most column
//Updates the datatable
updateDataTable();
//IF the user has clicked "+" image in datagrid right most column
if(e.CommandName.ToString()=="+")
{
// Adds a new row to datatable, so that after binding
// to datatagrid, it shows a blank row in datagrid
DataRow drow=dt.NewRow();
dt.Rows.Add(drow);
updateDataTable();
bindData();
}
//If the user clicks "-" image button in datagrid's left most column
else if(e.CommandName.ToString()=="-")
{
//The first column of Datagrid has serial number(1,2,3,4...)
//If the user clicks "-" it removes row at that position
dt.Rows.RemoveAt(Convert.ToInt32(e.Item.Cells[0].Text)-1);
}
bindData();
}
}
}
/* Update the datatable before moving to some other page in Datagrid etc*/
private void updateDataTable()
{
for(int k=0;k
